Abstract PGE132 v6.0.25 -- PGE132 was updated to include the MAIAC GIBS images for MCD19A1/A2 and A3 products. Following specific changes were made to enable this:

1. Define new GIBS MAIAC ESDTs and update the GIBS ICD for MAIAC STD and NRT images

2. Include new color LUTs for MAIAC MCD19A1/A2 products.

3. Updated code to distinguish between the MAIAC STD and NRT GIBS ESDTs.

4. Added loader module specific changes to load MAIAC inputs

5. Changed archiving to handle 'GranuleDate/Time' instead of production to accommodate the MCD19A3 product

Problem Statement The operational GIBS L3 Land process for Collection 6 (PGE132) needed updates to include the GIBS images from the MAIAC suite of products, both in near-real-time (NRT) and standard (STD) processing.
Description of Change PGE132 was updated to include the MAIAC GIBS images for MCD19A1/A2 and A3 products. Following specific changes were made to enable this:

Data Granules to be Used for Science Testing PGE132 v6.0.25 has been tested at MODAPS, both in the NRT and STD stream and the results have been evaluated and confirmed by LDOPE, in-house and through the GIBS WorldView test instance.
Justification This PGE132 version (6.0.25) has been updated to include the C6 MAIAC daily and 8-day products, MCD19A1/A2 and MCD19A3 respectively that were missing from the original GIBS C6 Land re-processing.
