Isobaric main anallysis data. The tar file contains ~24 hourly data in format sgpallruc40isobX1.00.yymmdd.HH0000.raw.grb. No.2: sgpfnnallruc40isobX1.00.yymmdd.ZZ0000.raw.grb.BBfYY. Isobaric main forecast data. It is picked up when the analysis data is missing. where ZZ = cycle time BB = the base time from which the data is forecasted YY = the number of hours forecasted from the base time (BB) ZZ = BB + YY(the hour of the forecasted data ) No.3: sgpallruc40hybrX1.00.yymmdd.hhmmss.raw.tar.gz. Hybird analysis data. The tar file contains ~24 hourly data in format sgpallruc40hybrX1.00.yymmdd.HH0000.raw.grb. It is only available for 980407-980411.

We will start sending the data on a daily basis next week. We will also be sending out one week's worth of backlog data per day starting 8/6/98. Additional Notes: RUC2(Rapid Update Cycle) data is provided by National Centers for Environment Prediction (NCEP). It is hourly model data in GRIB format. Please see http://maps.fsl.noaa.gov/ for the detailed information on RUC2 data. We currently collect RUC2 isobaric main and surface analysis data.
