Hi Thiha: We are currently reviewing the ncServer interface and it will probably change some in the future. We will likely make it much easier for you to make a request using latlon, rather than have to understanbd the coordinate system. We will try not to change the endpoints, eg http://motherlode.ucar.edu:8080/thredds/ncServer/model/NCEP/NAM/CONUS_12km, and for the forseeable future that one will work. BTW, you might want to use the dataset http://motherlode.ucar.edu:8080/thredds/ncServer/fmrc/NCEP/NAM/CONUS_12km/NCEP-NAM-CONUS_12km_best.ncd instead of ones like "NAM_CONUS_12km_20070319_1800.grib2". If you need more dynamic info, the correct thing is to get the catalog (in XML) and parse that for the current info.
