Abstract Revise ocean large-mode aerosol LUT and fix ocean aerosol quality assurance flag.
Problem Statement - Ocean aerosol quality assurance flag incorrectly set to 11 for no retrieval condition.
- The ocean large mode aerosol table, big_v2c1.dat, requires update.
Description of Change - Ocean aerosol quality assurance flag reset to 15 for no retrieval condition.
- Implement new LUT table, big_v2c1.dat version 5
Products Affected MOD04_L2
Software Affected PGE04
Processing String to Receive the Change Terra Forward, Terra Reprocessing
Downstream Product Effects L2 Aerosol products propagate into the Atmosphere L2 Joint Product (MODATML2) and further into daily, weekly and monthly L3 products. However, there are no cross-product statistics involving the Aerosol products and other Atmosphere product parameters.
Data Granules to be Used for Science Testing A limited test spanning 5 sequential days was undertaken to verify the PGE04code changes at L2 and L3.
Justification Eliminates confusing and/or misleading information. Implementation of revised ocean LUT improves Aerosol data product.
Effective Date for Implementation of Change Start of C5 Terra Reprocessing.
Status PI approved. Michael King approved for Atmosphere, Vincent Salomonsom approved.
