The latest version of rNOMADS is now available on CRAN. This update resolves several minor bugs and one major one involving multiple variable/level selections when using the ModelGrid function. I have also added support for two more models on NOMADS: Climate Forecast System Flux Products and Climate Forecast System 3D Pressure Products. This brings the total number of real time model products supported by rNOMADS to 57. A quick test of the Climate Forecast System Flux Products produced the following image of surface albedo for 1200 GMT on July 4th, 2014:
In other news, data curators at the University Corporation for Atmospheric Research (UCAR) are currently investigating rNOMADS as an open source software package to read their GRIB archive. UCAR hosts a series of model archive data, some of which is freely available to the public. Their specific interest is in using rNOMADS to read their archive of the FNL model. They have gotten wgrib2 to work on MAC OS X, allowing rNOMADS GRIB functionality to be extended to Macintosh machines.
