GLOBAL WARMING: FEATURES AND IMPACT ON LIFE IN MEGACITIES
<p>The article considers one of the key factors affecting the climate - human activity. First of all, it is associated with emissions of carbon dioxide into the atmosphere, which creates a kind of greenhouse above the surface of the planet. The second factor is related to excess solar energy, which has accumulated over millions of years in oil, gas, coal, peat and other fossil hydrocarbons. Particular attention in the study is paid to those problems and methods of solution that can help or weaken global warming.</p>

CrIS PANs megacity dataset for São Paulo and Lagos
<div class="page"> <div class="layoutArea"> <div class="column"> <p>The COVID-19 pandemic perturbed air pollutant emissions as cities shut down worldwide. Peroxyacyl nitrates (PANs) are important tracers of photochemistry that are formed through the oxidation of non-methane volatile organic compounds (NMVOCs) in the presence of nitrogen oxide radicals (NO<sub>x</sub> = NO + NO<sub>2</sub>). We use satellite measurements of free tropospheric PANs from the S-NPP Cross-Track Infrared Sounder (CrIS) over eight of the world's megacities: Mexico City, Beijing, Los Angeles, Tokyo, São Paulo, Delhi, Lagos, and Karachi. We quantify the seasonal cycle of PANs over these megacities and find seasonal maxima in PANs correspond to seasonal peaks in local photochemistry. CrIS is used to explore changes in PANs in response to the COVID-19 lockdowns. Statistically significant changes to PANs occurred over two megacities: Los Angeles (PAN decreased) and Beijing (PAN increased). Our analysis suggests that large perturbations in NO<sub>x</sub> may not result in significant declines in NO<sub>x</sub> export potential of megacities.</p> </div> </div> </div>
