Hi Marshall, After checking with my colleague, we have a solution for you that is to use the ncml to aggregate these datasets. You can save the following lines to your local file and modify accordingly. Here is the ncml example: <?xml version="1.0" encoding="UTF-8"?> <netcdf xmlns="http://www.unidata.ucar.edu/namespaces/netcdf/ncml-2.2"> <aggregation dimName="time" type="joinNew"> <variableAgg name="t"/> <variableAgg name="TEMP"/> <variableAgg name="DQF"/> <netcdf location="file:/users/yuanho/downloads/OR_ABI-L2-ACHTF-M6_G16_s20221650010205_e20221650019513_c20221650022457.nc"/> <netcdf location="file:/users/yuanho/downloads/OR_ABI-L2-ACHTF-M6_G16_s20221650000205_e20221650009513_c20221650013056.nc"/> </aggregation> </netcdf> Yuan Ticket Details =================== Ticket ID: LEL-566313 Department: Support IDV Priority: Normal Status: Open =================== NOTE: All email exchanges with Unidata User Support are recorded in the Unidata inquiry tracking system and then made publicly available through the web.
