COVID-19 Impact on Asian Emissions: Insight from space observations (NASA Terra/MOPITT and ESA S5P/TROPOMI)
March 27, 2020, 8 a.m.
Left Map - showing MOPITT total tropospheric CO column values, averaged for the period following the 2019 Chinese New Year (CNY) holiday (4-10 February).
Center Map - Same for the period following the 2020 CNY holiday (24-30 January), during the lockdown.
Right Map - Change in CO between the two periods (2020 minus 2019).
Initial results indicate that CO in the Beijing-Chengdu-Shanghai-Wuhan area has decreased on average by almost 6%, with more than 46% reduction locally. CO increase over SE Asia is consistent with seasonal fires, also observed by the MODIS instruments. Gray indicates missing values due to clouds. © 2020 UCAR.Access the full article from the Related URL below.
