Assessment and Quantification of Methane Emission from Indian Livestock and Manure Management by Anuja Samal, Saroj Kumar Sahu, Ashirbad Mishra, Poonam Mangaraj, Shantanu Kumar Pani, Gufran Beig

“…Abstract Methane (CH4) is one of the most abundant organic trace gases in the atmosphere having a strong global warming potential of 28 in 100 years, is a significant GHGs, and has a vital role in atmospheric chemistry and climate change. India is home to the largest number of livestock in the world and is responsible for higher methane emissions from enteric fermentation and manure management. …”

Unexpected Impact of COVID-19 Lockdown on the Air Quality in the Metro Atlanta, USA Using Ground-based and Satellite Observations by Guanyu Huang, Reyla Ponder, Amber Bond, Hailey Brim, Akua Temeng, Aaron R. Naeger, Lei Zhu

“…Further studies are needed to understand the impacts of reduced human activities on atmospheric chemistry. We also found TROPOMI and ground measurements have disagreements on NO2 reductions, as collocated TROPOMI observations revealed ~23% and ~21% reductions of tropospheric NO2 columns over NR and UA stations, respectively. …”
