The GMAO supports a variety of customers with operational, reanalysis and reprocessing and mission products. Operational and specialized mission products are generated real time from the Data Assimilation System (DAS) that operates 24 hours a day/7 days a week. Reanalysis and reprocessing is accomplished utilizing subsets of the DAS designed to meet customer output requirements.
DAS Overview
The GMAO Data Assimilation System (DAS) is executed four times per day for each synoptic time. Typically a single forecast at 0Z is produced. The input data are GDAS output files with additional data from AIRS observations. Output products are delivered to the Goddard archive on the morning of the next day and in near realtime to the NCCS data portal during mission (field campaign) support.
