DESCRIPTION;LANGUAGE=en-US:Hi Everyone\,\n\nSOCAAR is pleased to announced
next Seminar.\n\n\nWednesday\, April 6\, 2022\n\n3:00 – 4:00PM\n\n\nMatt
hew Cooper\nPhysical Science Officer\n\nEnvironment and Climate Change Can
ada\n\n\n\n\nObserving global fine-scale changes in ambient NO2 during COV
ID-19 lockdowns using satellites\n\nNitrogen dioxide (NO2) is an important
contributor to air pollution with serious health effects. Many reports ha
ve shown that NO2 concentrations decreased in 2020 during COVID-19 lockdow
ns\, but these studies are limited by the availability of air quality moni
toring globally. In this talk\, I will show how we use satellite observati
ons to infer global fine resolution (~1km) ground-level NO2 concentrations
. Using these observations\, we find that mean NO2 concentrations are ~30%
lower in countries with strict COVID-19 lockdowns than in those without
. I will also present case studies that compare lockdown-driven changes to
long-term NO2 trends\, and show how the sensitivity of NO2 to lockdowns v
aried across cities\, countries\, and emissions sectors.\n\n\n\n\n\n\n____
