rda-bufr-decode-ADPsfc-littler

This project contains Fortran source code to read BUFR files containing NCEP ADP surface observations, convert the observations to ASCII format, and then convert the ASCII data to little_r format. The little_r formatted files then can be used as input to the WRF model.
BUFR observation files are archived and available for download in the NCAR Research Data Archive (RDA) dataset ds461.0.

To compile, run the install.sh script under the /install directory to complete the compilations. The most recent version of BUFRLIB is required to compile this code; software download and installation instructions are provided at:

https://emc.ncep.noaa.gov/emc/pages/infrastructure/bufrlib.php

The executables will be placed in the /exe directory. Run the desired executable and enter the BUFR input file name to extract the basic meteorological varibles into formatted text format.

exe/bufr_adpsfc2ob.x:        used to convert gdas.adpsfc.tHHz.YYYYMMHH.bufr files to ASCII format.
exe/bufr_sfcshp2ob.x:        used to convert gdas.sfcshp.tHHz.YYYYMMHH.bufr files to ASCII format.
exe/surface_obs2littler.x:  used to convert/combine obs format files into one little_r format file.
