Daily 2-m temperature, 2-m specific humidity, and aerosol optical thickness at 550 nm

The 2-meter air temperature (T2M), 2-meter specific humidity (QV2M), and aerosol optical thickness (TOTEXTTAU) between January 1st and May 16 in 2020 are from the The Modern-Era Retrospective analysis for Research and Applications, Version 2 (Randles et al., 2017).Each spreadsheet's 18 columns represent each of the three variables averaged over the 20 countries. The rows represent the 137 days between January 1st and May 16 in 2020.
