rNOMADS (version 2.5.3)

An R Interface to the NOAA Operational Model Archive and Distribution System

Description

An interface to the National Oceanic and Atmospheric Administration's Operational Model Archive and Distribution System (NOMADS, see for more information) that allows R users to quickly and efficiently download global and regional weather model data for processing. rNOMADS currently supports a variety of models ranging from global weather data to an altitude of over 40 km, to high resolution regional weather models, to wave and sea ice models. rNOMADS can retrieve binary data in grib format as well as import ascii data directly into R by interfacing with the GrADS-DODS system.
