SeaHawk/Hawkeye L1B not a valid input mission

by daurin » Fri Jun 16, 2023 4:57 pm America/New_York

Goal: Automate processing of Hawkeye to L2 and beyond using non-default settings (e.g., output rhos_752 or turn off cloud masking) necessitating scripted command line interface L1A->L2. First attempts to process using default settings fails in both the GUI and CLI.
____________________________________
System: MacOS Ventura 13.4, SeaDAS 8.3.10, OCSSW
____________________________________
Initial Steps: Download L1A from Level 1&2 Browser. Process to L1B, either using SeaDAS GUI or command line interface. No apparent errors.
____________________________________
Problem: Opening L1B in SeaDAS GUI asks for NetCDF format (Generic vs. CF-Convention), but L1B file appears okay either way in GUI (e.g., displays Bands as expected) until trying to use GUI>SeaDAS-Toolbox>SeaDAS Processors>l2gen, when it reports that the file is not recognized as a valid mission and GUI interaction to most features is disabled:

"# PRIMARY INPUT OUTPUT FIELDS
ifile=/Users/daurin/Megalink/SeaHawk/L1B/SEAHAWK1_HAWKEYE.20230512T213239.L1B.hdf
# # WARNING!!! File /Users/daurin/Megalink/SeaHawk/L1B/SEAHAWK1_HAWKEYE.20230512T213239.L1B.hdf is not a valid input mission: Mission=null


# SUITE
suite=OC

# ANCILLARY INPUTS Default = climatology (select 'Get Ancillary' to download ancillary files)"
____________________________________
Tried: Process using command line l2gen:

Code: Select all

l2gen --ifile=/Volumes/Megalodon/SeaHawk/L1B/SEAHAWK1_HAWKEYE.20230512T213239.L1B.nc --geofile=/Volumes/Megalodon/SeaHawk/L1A/SEAHAWK1_HAWKEYE.20230512T213239.GEO --ofile=/Volumes/Megalodon/SeaHawk/L2/SEAHAWK1_HAWKEYE.20230512T213239.L2.OC.nc
Interestingly, this appears to recognize the L1B as Hawkeye, and appears to work:

For processing HawkEye to level-2 you can use the GEO file and the L1A file as inputs to l2gen. You don't need the L1B file for processing HawkEye to level-2. This behavior of using GEO and L1A files as input to l2gen is similar to VIIRS processing. Each mission can be somewhat unique in the pre-level2 phases of processing.
