Ongoing climate change, caused by the accumulation of greenhouse gases in the atmosphere, is happening on define the composition of atmosphere timescale of decades to atmodphere and is driving environmental changes worldwide. Combo shows the India Gate war memorial on 17 October top and after air pollution levels started to drop during a day nationwide lockdown in New Delhi, India, April 8, bottom.

Improvement in air quality can be driven by many processes, including emission reduction and changes in meteorological conditions as explained in this Bulletin. In contrast, the impacts of air pollution occur near the surface, on timescales of days to weeks, and across spatial scales that range from local for example, urban centres, see the photo below to regional.

Despite these wide-ranging differences, air quality and climate change are strongly interconnected Fiore et al. The new WMO Air Quality and Climate Bulletin will report annually on the state of air quality and its connections to climate change, reflecting on the geographical distribution of and changes define the composition of atmosphere traditional pollutants. What is the ph for an acidic basic and neutral substance pollutants include short-lived reactive gases such as ozone — a trace gas that is both a common air pollutant and a greenhouse gas that warms the atmosphere — and particulate matter — a wide range of tiny particles suspended in the atmosphere commonly referred to as aerosolswhich are detrimental to human health and atmosphre complex characteristics can either cool composigion warm the atmosphere.

Air quality vefine climate are interconnected because the chemical species that affect both are linked, and because changes in one inevitably cause changes in the other. Human activities that release long-lived greenhouse gases into the atmosphere also enhance the concentrations of shorter-lived sefine and particulate matter in the atmosphere. For example, the combustion of fossil fuels a major source of carbon dioxide CO 2 also emits nitrogen oxide NO into the atmosphere, which can lead to the photochemical formation 1 of ozone and nitrate aerosols.

Similarly, agricultural activities which are major sources of the greenhouse gas methane emit ammonia, which then forms ammonium aerosols Pye et al. Policy changes that seek to improve air quality thus have repercussions on those policies that seek to limit climate change, and vice versa. For instance, a drastic reduction in fossil fuel combustion to reduce greenhouse gas emissions will also reduce air pollutants associated with that activity, such as ozone and nitrate aerosols. Policies to reduce particulate matter pollution to protect human health may remove the cooling effect of sulfate aerosols or the warming effect of black carbon soot particles.

Finally, changes in climate can defihe pollution levels directly. For example, the increased frequency and intensity of heatwaves may lead to the additional accumulation of pollutants close to the composifion. This issue of the WMO Air Quality and Climate Bulletin provides an update on the current global distribution of define the composition of atmosphere matter, highlighting the contributions of extreme wildfire events in the year The ensuing COVID pandemic triggered a worldwide economic downturn inwhich led to reduction of the emissions of air pollutants, yielding a range of impacts on surface what is exchange rate risk free tropospheric cefine levels of ozone and particulate matter Gkatzelis et al.

It ends with a recent update on the global health impact of long-term exposure to ozone and particulate matter pollution. Inhaling particulate matter smaller than 2. Human and natural sources contribute firebase realtime database tutorial android example PM 2. Using the PM 2. Intense wildfires generated anomalously high PM 2.

In January and atomsphere preceding December, southwestern Australia was affected by widespread wildfires, which exacerbated air pollution define the composition of atmosphere also WMO Aerosol Bulletin Smoke from the Australian fires also led to temporary cooling define the composition of atmosphere the southern hemisphere, comparable to that caused by ash from a volcanic eruption Fasullo et al.

Enhanced wildfire activity also occurred in the Yakutia region of Siberia, in the US state of California and many defime regions of the western United States of America. Regularly occurring wildfires in central South America and central Africa were also higher than the — average. The lower-than-average PM 2. The variability of PM 2. While the eastern Sahara had lower surface PM 2. Define the composition of atmosphere dust emissions also occurred in the desert regions of northern China and Mongolia.

Aerosols originating from human activity have the largest impact on human health because they contribute most to PM 2. Define the composition of atmospherethere was an unprecedented define the composition of atmosphere in certain human activities, such as vehicle transport and aviation, due to the economic downturn associated with the COVID pandemic. The increase in PM 2.

A better understanding of the multiple natural and anthropogenic sources of emissions and the meteorological influences on emissions and on the spread of the atmospherw pollution define the composition of atmosphere critical for advancing our modelling of atmospheric composition and its changes. Combining computer models with near-real-time observations — a process known as data assimilation — has been a major factor behind advances in numerical weather prediction in recent decades Bauer et al.

Computer-simulated fields corrected by observations are known as analyses corrected by observations are known analyses. The analyses are used as initial conditions for the daily CAMS forecasts and for the retrospective study of atmospheric composition for understanding the spatial distribution, trends and variability of trace gases and aerosols. The Atmosphete Modeling and Assimilation Office used satellite retrievals of fire locations and intensity to analyse wildfires in the extratropical regions of Eurasia and North America in The wildfire season was marked by extreme fires in Siberia and the western United States and uncharacteristically weak fire activity in Alaska and Canada, compared with the situation in previous decades.

Comparisons with estimates of historical fire emissions — indicated that was an exceptional year in terms of total pyrogenic carbon released into the atmosphere by wildfires in Siberia and the western United States, with extremely dense and expansive smoke plumes visible from space Figure 2. The Fire Weather Index FWI; Wagner,attmosphere commonly used measure of fire intensity and potential, provided further insights into the anomalous fire season by quantifying how much influence key meteorological parameters such as atmisphere, wind, precipitation and humidity had on fire danger.

The strong relationship between negative departures from the FWI climatology and reduced potential for fires was also evident in Canada and Alaska. The behaviour of the fires in the major burning regions in the northern hemisphere extratropics can therefore be define the composition of atmosphere least partly attributed to persistent weather patterns in the boreal summer offor example, a historic high-latitude heatwave in Siberia.

These conclusions are define the composition of atmosphere because they may reflect a strengthening signal of changing climate on weather-induced mechanisms that alter fire behaviour and pollutant emissions on large scales. Several publications have pointed out that extreme heatwaves and dry spells are projected to be exacerbated by climate change Define the composition of atmosphere, ; one study concluded that the prolonged Siberian heatwave of would have been almost impossible without human influence Ciavarella et al.

To assess the impact of the fires on outdoor air pollution across North America, the Global Modeling and Assimilation Office estimated how many people were exposed to varying levels of pollutants Stieb et al. Using data from the multi-pollutant Air Quality and Health Index, the Office found that the number of people who likely experienced unhealthy levels of air pollution increased during the fire season and compoeition in the second week of September, when most of the intense fires occurred in the western United States.

Many governments around the world responded to the COVID pandemic by restricting gatherings, closing schools and imposing lockdowns. Compostiion stay-at-home policies atmsphere to an unprecedented decrease in pollutant emissions. The data were used to analyse changes in air quality for the main pollutants, such as particulate matter PM 2. The changes were examined for different lockdown stages, namely pre-lockdown, partial lockdown, full lockdown and two periods of relaxed restrictions between January and September The observational study investigated how changes in air quality were affected by emissions and regional and local meteorology in compared with the period — During the various lockdown define the composition of atmosphere, emissions of air pollutants fell drastically across the globe due to travel restrictions imposed to stem the spread of COVID No clear indication was observed for other pollutants, define the composition of atmosphere suggests that sources other than vehicle emissions also contributed substantially to the change in air quality.

Some Chinese cities showed similar increases in Define the composition of atmosphere 2. Under certain polluted conditions, an increase in ozone atmospheree be expected, with decreases in its precursors, due to the complexities of ozone chemistry. Analysis of the total oxidant showed that primary NO 2 emissions at urban locations were th than the O 3 production, whereas at background sites, O X was mostly driven by the regional contributions rather than local NO 2 define the composition of atmosphere O define the composition of atmosphere concentrations.

This unplanned air-quality experiment can serve as a benchmark for policymakers to understand whether existing air-quality regulations would protect public health. While lockdowns had a clear impact on air quality in urban areas, the spatial and temporal extent of that impact, the specific role of meteorology and of episodic contributions e. It is still necessary to better understand changes in how secondary pollutants chemically respond to emission changes under complex conditions what is nosql database explain with example how socioeconomic drivers may affect future air quality.

The implications for regional and global policies are also significant, as the Sokhi et al. Figure 6 shows the long-term ozone concentration variability at three very remote locations. All three sites show a strong seasonal cycle, but the timing of the annual maximum varies due to differences in photochemistry and the weather patterns that transport ozone to these remote sites Cooper et al. Figure 6 also shows the long-term changes in ozone concentration near the Alpine summit of Zugspitze in southern Germany 2 m elevation.

Depending on highly variable weather patterns, these ozone values can be representative of air that originates within the polluted boundary layer4 of Europe or air that originates beyond western Europe. Ozone concentration increased during the period from when records began until the late s. Sinceozone compositlon has changed relatively little, although levels have decreased slightly during the warm months of May-September, when Zugspitze is most frequently affected by regional European pollution Cooper et al.

A recent study has shown that ozone levels at Monte Cimone were unusually low in the boreal spring and summer oflikely due define the composition of atmosphere reduced European emissions during the COVID economic downturn Cristofanelli et al. Similar reductions are seen at Zugspitze, km to the north Figure 7. Low ozone values in May, June and July were also observed at the hilltop site of Hohenpeissenberg, Germany, but the reductions relative to multi-year average were not as low as those observed at Zugspitze, 40 km to the south.

The spring and summer ozone reductions at Monte Cimone and Zugspitze are highly unusual and are lower than anything observed over the past two decades. These reductions are even greater than those observed in the free troposphere across the northern hemisphere mid-latitudes by weather balloons, lidar laser instrument and commercial aircraft in Steinbrecht et al. The Global Burden of Disease GBD initiative provides regular updates two-year cycle on premature death and disability from diseases and injuries in countries and territories Murray et al.

GBD quantifies global-scale exposure to ambient ozone pollution by combining observations from thousands of surface-air-quality monitoring stations worldwide with output from atmospheric chemistry models Schultz et define the composition of atmosphere. Similarly, exposure to PM2. Global exposure maps of ambient ozone and ambient PM2. Figure 8 shows ambient air-pollution mortality estimates from the latest GBD assessment Cant connect to this network problem et defind.

Global mortality due to ambient air pollution is dominated by particulate matter with 4. In total, global mortality increased from 2. Regionally, present-day total mortality is greatest in the super-region of Southeast Asia, East Asia and Oceania 1. Another major cause of premature mortality is household particulate matter, which is caused define the composition of atmosphere the burning of solid and liquid fuels for cooking and home heating. GBD assesses mortality due to the burning of solid fuel for cooking and estimates that there were 2.

Therefore, the GBD estimate of total global mortality due to ambient and household air pollution for the year is 6. While total mortality due to household particulate matter has xtmosphere decreased in these regions sincemortality rates remain high, especially in sub-Saharan Africa, where the mortality rate due to household particulate matter is roughly three times the rate due to ambient particulate matter.

An in-depth analysis of global mortality due to ambient and household air pollution can be found in the State of Global Air Health Effects Institute, In conclusion, this issue of the WMO Air Quality and Climate Bulletin highlights the critical role that observations play in monitoring the state of the atmosphere. Long-term, consistent measurements enable the community to understand how conditions have changed relative to the past define the composition of atmosphere empower air quality and climate models to improve simulations of the atmosphere.

There is still room for improvement — model predictions will always be somewhat uncertain — but in times of rapid shifts in human activity as was the case infilling observational gaps for key species will greatly improve our ability to model atmospheric changes as they occur.
