NCEP GDAS Satellite Data 2004-continuing
d735000
| DOI: 10.5065/DWYZ-Q852
Abstract:
This dataset contains a subset of the level 1b or higher satellite data products used in the NCEP Global Data Assimilation System. These files can be used with the Weather Research Forecast (WRF) Data Assimilation (DA) system. However, they can be useful for a variety of applications, particularly where conventional data is scarce.
File sizes may vary due to operational changes.
