| Abstract | PGE120 V6.1.12 -- New MxD21 products added. Will start to use the PGE125 V6.1.5 in GIBS C61 Atmosphere L2 forward processing. |
| Problem Statement | Update the GIBS projection code to include the new C61 MxD21 L2 projected products for STD and NRT processing. |
| Description of Change | The C61 PGE120 V6.1.12, used for GIBS swath to tile projection, has been updated to include the L2 MxD21 specific projection products of MxR21 for day and night, respectively. |
| Products Affected | MODIS C61 L2 JPL LST (MxD21) from STD and NRT |
| Software Affected | PGE120 V6.1.12 |
| Processing String to Receive the Change | Terra and Aqua Forward Processing. Terra and Aqua Reprocessing. NRT. |
| Downstream Product Effects | None |
| Data Granules to be Used for Science Testing | The PGE120 V6.1.12 have been tested by running over an extended period from nrt4 test instance and have been confirmed from the GIBS WorldView test instance. |
| Justification | This updates the PGE120 for inclusion of the L2 JPL LST (MxD21) projected products (MxR21), to be used for the eventual generation of the MxD21 L2 GIBS images from STD and NRT. |
| Effective Date for Implementation of Change | Has been in effect on nrt3/4 since July 21, 2021. Awaiting implementation on STD, following a short science test on STD stream. |
| Status | Major algorithm development completed. Sadashiva Devadiga approved on 07/30/2021. Chris Justice approved 07/30/2021. Gang Ye approved on 07/30/2021. |
