GEOS-Chem Input Data on AWS cloud

The GEOS-Chem Input Data portal provides essential datasets for GEOS-Chem Classic, GCHP, and HEMCO. This includes NASA/GMAO MERRA-2 and GEOS-FP meteorological products, chemistry input data, emissions input data, and other smaller datasets such as model initial conditions. We are pleased to announce that we are now part of the AWS Open Data Sponsorship Program. We will continuously upload and maintain the data in an S3 Bucket (s3://geos-chem) for convenient access.

In the following chapters, we will describe how the GEOS-Chem Input Data portal is organized and how to access the data stored there.
