Download datasets for MM5 from NCAR

A number of datasets which can use used as input to MM5 can now be download directly from the NCAR/DSS web site:

• Only a limited number of datasets are available online
• The data is free to all users to download

Available GRIB datasets: (for input to REGRID)

• NCEP GRIB GDAS (ds082.0)
  • Available from July 1976 to March 1997
  • This is the original ON84 dataset, which has been converter to GRIB
  • https://dss.ucar.edu/datasets/ds082.0/data/
• NCEP GRIB GDAS (ds083.0)
  • Available from May 1997 to current
  • https://dss.ucar.edu/datasets/ds083.0/data/
• NCEP Final Analysis (FNL) (ds083.2) *
  • Available from July 1999 to current
  • http://dss.ucar.edu/datasets/ds083.2/data/
• NCEP/NCAR Reanalysis (ds090.0) *
  • Available from January 1948 to current
  • http://dss.ucar.edu/datasets/ds090.0/data/pgbf00-grb2d/
    
• AWIP data (ds609.2) *
  • Available from April 2000 to current
  • http://dss.ucar.edu/datasets/ds609.2/data/
    
• Information about the use of these and other datasets in MM5 are available from MM5V3/data

* Recommended datasets
* Dataset may also be used as input for the WRF model (WPS)

Available observational datasets: (for input to LITTLE_R)

• Surface and upper-air observational data (in ADP format) is also available to users
  1. Surface and Ship data (ds464.0)
  2. Upper Air data (ds353.4)
• Once you have the ADP data on your machine, you can use the script adp_to_little-r.csh (inside that latest FETCH TAR file - after Jan 21, 2004) to convert it to LITTLE_R input format
• If you run RAWINS, you can use the ADP data directly
• Information about the use of these datasets in MM5 are available from MM5V3/data

Thanks to all the NCAR/DSS staff that worked
hard to make this possible for MM5 users
