Hi Brian,

There is no time dimension in the netCDF GOES 16 files (but it does have time 
variable), so you need to write
a ncml file to do the aggregation. Here is some information about ncml:

https://docs.unidata.ucar.edu/netcdf-java/current/userguide/ncml_aggregation.html

let me know if you need help to create a ncml file.

Thanks,
Yuan
