Hi Sarah: I dont really understand your problem. Apparently you used the service at http://nomads.ncdc.noaa.gov/thredds/ncss/grid/nam/200812/20081201/nam_218_20081201_0000_000.grb/dataset.html to extract some data. What is the other souyrce of data that you are comparing to where the lat/lon doesnt match? > Hello, > > My name is Sarah Reinke and I am a graduate student here at UW > Milwaukee Wisconsin.
