Hey, If you are running a python environment, try this: >>> import netCDF4 >>> f=netCDF4.Dataset('l2/PACE_OCI.20240501T000458.L2.OC_AOP.V3_1.nc') >>> f['sensor_band_parameters/wavelength_3d'] <class 'netCDF4._netCDF4.Variable'> int32 wavelength_3d(wavelength_3d) long_name: wavelengths units: nm _Fil...

Excited to see the new code implemented in tag V2025.1

Cheers!

Dear Support, It's first time I see something like this. The OCI granules are always 5-min apart, but these two are odd: PACE_OCI.20250312T183450.L1B.V3.nc PACE_OCI.20250312T183505.L1B.V3.nc Please forward this to the group who can handle it if it's an artifact.

Thanks,
Yes, the search portal has now been up-to-date

Thanks, it works.

Dear Support, I installed the latest V2025.1 In $OCSSWROOT/share/viirs/npp/instrument_defaults.par, the current setting: ... rsb_dynamic_lut_file=$OCVARROOT/viirsn/cal/OPER/VIIRS_NPP_CAL_RSB_DYNAMIC_LUT_20111122_20240107_v3.1.0.25_20230901_obpg.nc ...

Just found it is also because of compression in data file. We must use deflated netCDF file, then the spectrum view works well and faster. Any compression (even level=1 only) wouldn't work. I'm using the nccopy command to do the deflation, it takes time for big files. It is not a beautiful solution....
