NCEP/EMC U.S. Stage IV imagery

Summary

This dataset contains the National Centers for Environmental Prediction (NCEP) Environmental Modeling Center (EMC) GIF Imagery including Hourly Stage II GIF, Daily Stage II GIF, Daily RFC GIF, 6-Hourly Stage IV GIF, and Daily Stage IV GIF. Depending on the time period selected, all GIF types may or may not be available. Please see the GCIP/EOP: Surface NCEP Ancillary Catalogue of Available GCIP Precipitation Data (NCEP/EMC). This dataset is provided as is and was not quality controlled by UCAR/JOSS. Beginning 1 Jan 2002, the analysis grid has been changed to conform with the official NWS HRAP grid. File names have also been changed. See the readme provided with this dataset for details. As of April 2017 this data includes Alaska and Puerto Rico stations.
