Effect of Lockdown due to COVID-19 on the Aerosol and Trace Gases Spatial Distribution over India and Adjoining Regions by Madineni Venkat Ratnam, Perumal Prasad, Sivan Thankamani Akhil Raj, Ibrahim Hoteit

“…Changes in the background meteorology (decrease in wind speed and increase in water vapour) during the lockdown made these aerosols stagnant and increased their size over central India, leading to higher AOD. …”

Source Impact Analysis Using Char-EC/Soot-EC Ratios in the Central Indo-Gangetic Plain (IGP) of India by Manisha Mishra, U.C. Kulshrestha

“…Furthermore, several diagnostic ratios (EC/fPM, OC/EC, char-EC/soot-EC, and WSOC/OC) indicated that the characteristics of the carbonaceous aerosols significantly differed between seasons, with emission sources, seasonal meteorology, and atmospheric chemistry driving the variation in abundance. …”

The Impact of Lockdown on eBC Mass Concentration over a Semi-arid Region in Southern India: Ground Observation and Model Simulations by Surya Nagi Reddy Palle, Chakradhar Rao Tandule, Raja Obul Reddy Kalluri, Balakrishnaiah Gugamsetty, Rama Gopal Kotalo, Lokeswara Reddy Thotli, Bhavyasree Akkiraju, Siva Sankara Reddy Lingala

“…The sharp decrease (~35%) of eBC mass concentration observed during the lockdown (LD) period as compared with before lockdown (BLD) period, was mainly due to the reduction of anthropogenic activities and meteorology. Furthermore, during the entire LD period, the net composite forcing at the top of the atmosphere (TOA) and at the surface (SUR) varied from −4.52 to −6.19 Wm −2 and −22.91 to −29.35 Wm −2, respectively, whereas the net forcing in the atmosphere (ATM) varied from 17.27 to 23.16 Wm−2. …”

Particulate Pollution in Korhogo and Abidjan (Cote d’Ivoire) during the Dry Season by Sylvain Gnamien, Véronique Yoboué, Cathy Liousse, Money Ossohou, Sékou Keita, Julien Bahino, Silué Siélé, Lamine Diaby

“…This study evaluates with a simple existing methodology particulate air pollution in two West African cities (Korhogo and Abidjan in Cote d’Ivoire) which have different population practices and local meteorology. From two measurement campaigns at about ten sites during the dry season and using the inverse distance-weighted interpolation method, maps of spatial variation in PM10 and PM2.5 concentrations are obtained at the scale of each of these cities, which provide a snapshot of the concentration levels to which populations are actually exposed. …”

First Measurements of Ambient PM2.5 in Kinshasa, Democratic Republic of Congo and Brazzaville, Republic of Congo Using Field-calibrated Low-cost Sensors by Celeste McFarlane, Paulson Kasereka Isevulambire, Raymond Sinsi Lumbuenamo, Arnold Murphy Elouma Ndinga, Ranil Dhammapala, Xiaomeng Jin, V. Faye McNeill, Carl Malings, R. Subramanian, Daniel M. Westervelt

“…Finally, the surface PM2.5 level and the aerosol optical depth were about 40% lower during the COVID-19 lockdown in 2020 than the corresponding period in 2019, which cannot be attributed solely to changes in meteorology or wildfire emission. Hence, our results highlight the need to implement clean air solutions in the Congo.…”
