PACE L2 OCI wavelength bands
Posted: Thu May 30, 2024 11:03 am America/New_York
PACE L2 OCI data from Earthdata (short name: PACE_OCI_L2_AOP_NRT, PACE_OCI_L2_IOP_NRT, ...),
for example: "https://obdaac-tea.earthdatacloud.nasa.gov/ob-cumulus-prod-public/PACE_OCI.20240520T180624.L2.OC_AOP.V1_0_0.NRT.nc"
has a parameter wavelength_3d assigned to Rrs and Kd (similar in for PACE_OCI_L2_IOP_NRT products)
Rrs (number_of_lines, pixels_per_line, wavelength_3d)
however, I can not find any attributed to wavelength_3d that could designed respective bands (seems me that wavelength_3d has 0 values).
In the L1B files, we can see the band parameters in the netcdf-file group parameter: 'sensor_band_parameters'
For example:
blue_wavelength: 314.5 316.1 318.1 ... 603.3 605.7
red_wavelength: 600.4 602.9 605.4 ... 892.1 894.6
however, the L2 products do not have the same number of bands. I am looking for the identification the wavelength assigned for each band. Where can I find this information?
