These are perl decoders that convert textual bulletins into netCDF formatted files. This package usually works in conjunction with the LDM package to convert incoming products to the netCDF format without storing the raw data. There are perl decoders for the following textual report types: METAR, buoy, upperair, and synoptic products. It is better to decode the textual reports in real time with the LDM because the textual reports do not have a year month fields in the reports. This package requires the installation of udunits, netCDF, and the perl-netCDF packages to work. To install the decoders with the LDM, add the following pqact entries into your LDM pqact.conf file.
