Hi David, Instead of trying to create individual netcdf files, you can use NcML to extract only wanted variables and runTimes for a set of files in a directory. If you do in ToolsUI, then the ring tab will let you write out a netcdf file with all the aggregations. Here's a sample NcML: <?xml version="1.0" encoding="UTF-8"?> <netcdf xmlns="http://www.unidata.ucar.edu/namespaces/netcdf/ncml-2.2"; enhance="true" > <attribute name="title" type="string" value="ForecastModelRun for all grb files"/> <aggregation dimName="run" type="forecastModelRunCollection"> <scan location="file:/local/robb/data/grib/nldas/" suffix="grb" dateFormatMark="NLDAS_MOS0125_H.A#yyyyMMdd.HHss" enhance="true" /> <remove name="Evaporation" type="variable"/> ... .... </aggregation> </netcdf> Also look at: http://www.unidata.ucar.edu/software/netcdf/ncml/v2.2/FmrcAggregation.html If you read in a file into the NcML tab in ToolsUI, it gives a complete representation of a typical file. If a dimension, attribute, and variable is not in the NcML, it's in the resulting file. When you read the NcML file in the ToolsUI viewer tab you should only get the results from the NcML There is a NcML tutorial that is worth looking at too. My test only included 2 files so the results was quick, it could be a time lag if there are many files. Robb...
