The trajectory sampler netCDF output variable
location_index_in_iodafilecan now be turned off, after we add two control variables:use_NWP_1_fileandrestore_2_obs_vectorfor users.use_NWP_1_file = .true., code reads in a single obs file for each epochrestore_2_obs_vector = .true., code restores obs locations as input IODA file, the previous remapping ioda index is suppressed.Related Issue
I have anther PR on splitfield for sampler to be merged to this PR, which handles
jedi.splitField: 1Test performed:
jedi.use_NWP_1_file: .true.
