MERRA Data

MERRA is an abbreviation for Modern Era Retrospective-Analysis for Research and Applications. The datasetsoriginates from the Global Modeling and Assimilation Office of NASA / Goddard Space Flight Center.The MERRA analysis are being conducted with the GEOS-5 Atmospheric Data Assimilation System(ADAS).

Resolution and Coverage

The model grid is 0.5 degree latitude and 2/3 degree longitude. It holds 1 hourly values with a global coverage.

Data Availability

The following five parameters are available from within the online-dataservices WindPRO:

{ !Parameter !Description |- |pressure |Sea level pressure |- |temperature |Temperature at 2 m above the displacement height |- |wDir |Wind direction at 50 m above surface |- |wSpeed |Wind speed at 50 m above surface | - |dispHeight |Displacement height |}
