| Initiator | Lorraine Remer |
| 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. |
