The new service is based on a custom combination of three reanalysis datasets: ERA-Interim, MERRA, and CFSR. The use of CFSR, which is released daily by the US national weather agencies, is what permits the rapid update. At the same time, the incorporation of ERA-I and MERRA allows for the correction of known inconsistencies in the historical CFSR data, and provides a more reliable indication of long-term conditions.
