First of all, GFS is in "Lat Lon" and the resolution is 0.5. So your code should read: GFS.modelgrid <- ModelGrid( GFS.Model.Data, grid.type = "latlon", resolution = c(0.5, 0.5),levels = c("surface","2_m_above_ground"), variables) However, since you pulled multiple forecasts from DODS, the above won't work unless you separate out each forecast.

I don't anticipate needing to release a new version of rNOMADS because of this. However: Abbreviations are going to change, for example: gfs_hd will become gfs_0p50 Some variables/levels will be removed, others will be added. If your code stops working, first try using NOMADSRealTimeList to check if the model you want is still in the NOMADS inventory. Also, NOMADS may be down for tomorrow and potentially longer, depending on how smoothly the transition goes, so be aware of that as well.

Check out the Wave model description on the NCEP web site: http://nomads.ncep.noaa.gov/txt_descriptions/Wave_model_forecast_doc.shtml It looks like the model does include hindcasts. I had a look at the grib and DODS filters and couldn't immediately tell which were hindcasts and which were not, but if they're there, rNOMADS can get them. Let me know if I can be of further assistance. Best, Danny Daniel C.
