Reforecasts help scientists better understand the model's ability to produce accurate weather forecasts. In addition to the reanalysis efforts, the CFS model was used to generate a reforecast of past weather forecasts. Wang, and Coauthors, 2010: The NCEP Climate Forecast System Reanalysis. The reanalysis method kept the model’s software constant and ran the model retrospectively from January 1979 through March 2011. The Climate Forecast System Reanalysis (CFSR) was an effort to generate a uniform, continuous, best-estimate record of the state of the ocean–atmosphere interaction for use in climate monitoring and diagnostics. The issue affects the following time series file types (28): If you improvise the metadata, the data itself is valid. Users who have already downloaded these files are encouraged to re-download these files on/after Friday, February 19, otherwise be aware of these facts when using your existing copy. At 22:00 UTC February 18, 2010, NCEI will begin bringing corrected versions of these files online. The issue, triggered during the conversion process between GRIB1 to GRIB2 by NCEP (to facilitate transmission and storage), caused the non-instantaneous fields (00-01, 01-02, 02-03 hr statistical) to appear instantaneous (00-00, 01-01, 02-02 hr statistical) when decoded. Notice to users who downloaded CFSR time series data prior to 22:00 UTC February 18, 2010:Ī format conversion issue was verified affecting the metadata in non-instantaneous CFSR time series files (28 of the 73 file types affected are listed below). Known CFSRR data issues are explained in the August 2011 CFSRR Known Issues Technical Document. NCEI and NCEP have identified that the "High-Priority Reforecast" datasets are roughly 99% serially complete at this time and may contain isolated damaged files.
