rNOMADS: An interface to the NOAA Operational Model Archive and
An interface to the National Oceanic and Atmospheric Administration's Operational Model Archive and Distribution System (NOMADS) that allows R users to quickly and efficiently download global and regional weather model data for processing. rNOMADS currently supports 54 models, ranging from global weather data to an altitude of 40 km, to high resolution regional weather models, to wave and sea ice models. It can also retrieve archived NOMADS models. rNOMADS uses an external series of routines called wgrib2 to read real time model data into R; this must be downloaded and installed separately. rNOMADS also offers limited support to reading archived data in GRIB1 format via the wgrib utility, which also must be downloaded and installed separately. Future versions of rNOMADS will have a native data reader.
