Abstract:
NCEP prepares a twice-daily global analysis at 2.5 degrees resolution on pressure levels as a product of their operational forecast system. The original data set as stored at the National Center for Atmospheric Research (NCAR) starts in July 1976 and is being updated continuously at NCAR. We make a subset of this data available beginning in 1979. We also make available selected monthly mean datasets that go back in time (for the northern hemisphere). As part of a research project supported by the National Science Foundation, the NCEP data has been processed by NCAR into a convenient format for climatological studies. Some quality control and error-checking are done at this time. CDC has processed the twice-daily data by linearly interpolating to fill in missing values and then creating a daily average from the twice daily data. The data set provided is the (00Z + 12Z)/2. (i.e., analyzed) data. In the analysis process, the observations are interpolated to a grid. Because (1) large parts of the world (and many levels) have no observations and (2) the data are not taken at one time (data is included if it is within 6 hours of the forecast time), a model forecast is used to help with the interpolation. Therefore, technically speaking, the data provided is an analyzed data set, which is a blend of observational and model data. These analyses are then INITIALIZED.
