hasSummary
  • This data set contains forecast products from the NCEP/NCAR Reanalysis Project. The resolution of the Reanalysis Forecast Model is T62 (209 km) with 28 vertical sigma levels. Every five days, beginning with 00Z 01 January, an 8 day forecast run is made. The initial time and outputs for every 12 hours are saved from this run. Pressure level and special level data are archived on the 2.5 by 2.5 latitude-longitude grid and flux fields are archived on the 192 by 94 Gaussian grid. Details on variables included are available elsewhere. Some special periods will be analyzed more than once to provide data for special research studies. For example, a special run of 1979 was made excluding most satellite inputs. This run could be used for evaluating the impact of satellite data on the forecasts. See DS090.0 [https://rda.ucar.edu/datasets/ds090.0/]for analysis and first guess fields. All data files for January 1948 to October 2005 are available as of 2005DEC29.
