NCEP/EMC U.S. Stage IV imagery https://data.eol.ucar.edu/dataset/21.087 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. 27 March 2020 - Data for 01 January 2020 was added when it was determined that this date had been omitted. 15 January 2020 - Data for 26 September 2019 was added when it was determined that this date had been omitted. 31 August 2020: Start and end dates/times on the files were updated. 7 October 2020: Stage 2 files will not be available after 28 July 2020. 7 October 2020: As of 20 July 2020, file names changed from st4*.gif to st4_conus*.gif. Starting on 20 July 2020, if both files exist, please refer to the st4_conus*.gif file for the most complete data. 4 February 2021: Files missing from January 2002, April 2003, January 2012, and January 2020 were added. Missing Data: January 28 - 30, 2019 - some stage 4 data missing April 4, 2019 - all data missing September 26, 2019 - all data missing November 21, 2019 - some stage 2 missing January 1, 2020 - all stage 4 and some stage 2 missing Identifiers * Local archive identifier: 21.087 * doi:10.26023/V0KW-KG0V-9J0W https://doi.org/10.26023/V0KW-KG0V-9J0W Versions 1.0 Citation Du, J. 2011.
