GMAO Releases MERRA-2 Climate Statistics Supplementary Dataset

The GMAO is pleased to announce the public release of the MERRA-2 Climate Statistics supplementary dataset. This dataset adds four file collections computed from MERRA-2 including monthly statistics that represent extreme temperature and precipitation events, as well as long term means intended to assist researchers with their analysis of MERRA-2. Data can be downloaded through GESDISC.

Reuters Publishes Article Using GMAO Product

"How air quality has improved during the coronavirus crisis" by Marco Hernandez quotes Ryan Stauffer and uses the GMAO GEOS-FP nitrate PM2.5 product and ground measurements of NO2, PM2.5, CO, and SO2 to look at the pollution drop in China, Italy, and India.

Earth Day Countdown Blog: T-17–Chemistry in the Atmosphere

Air pollution can appear as a gray or orange haze enveloping a city. What the naked eye can’t see are the hundreds of chemical reactions taking place to produce that pollution. NASA science can reveal a more complete picture of atmospheric chemistry.

MERRA-2 AMIP data (M2AMIP) now available

The GMAO is now providing MERRA-2 AMIP data (M2AMIP) a 10-member GCM experiment based on the climate forcing configuration used in MERRA-2. All modeling features in the model are identical to MERRA-2, except for the lack of observational analysis, and provides the model's realization of present day climate. Most MERRA-2 variables are available. For one member, hourly data have been preserved, otherwise the 10 members are monthly data, and include an ensemble mean.

GMAO continues to provide support for ASPIRE
