Time steps range from 1 min up to 1 month (original data are hourly). Spatial resolution of approx. 50 km. The data are available since Jan. 1980 and are regularly updated with approx. one month of delay.
The version 2 of MERRA was introduced in 2016 to replace the original MERRA dataset because of the advances made in the assimilation system.
