| Abstract | PGE641 2.0.10 Revised PGE641_LoaderModule.pl to stage GEOSIT_ASM_I1_L_SLV as input. No source code changes were needed. |
| Problem Statement | C2 Daily Gridded DSR/PAR, PGE641, was revised to use GEOSIT input, GEOSIT_ASM_I1_L_SLV, instead of the DFPITI3NXASM. The revision will go into place for leading edge processing in C2 for both NPP and JPSS1. |
| Description of Change | Revised PGE641_LoaderModule.pl to stage GEOSIT_ASM_I1_L_SLV as input. No source code changes were needed. |
| Products Affected | VNP18A1, VNP18A2, VJ118A1, and VJ118A2 |
| Software Affected | PGE641 2.0.10 |
| Processing String to Receive the Change | S-NPP Forward Processing. J1 Foward Processing. |
| Downstream Product Effects | All VIIRS land products. |
| Data Granules to be Used for Science Testing | A science test was conducted of PGE641 2.0.10-0 and results reviewed by LDOPE and the DSR PAR science team. Test results in AS4052. |
| Justification | In anticipation of the DFPITI3NXASM being discontinued. |
| Effective Date for Implementation of Change | PGE641 2.0.10 goes into use for JPSS1 starting with data from 8/6/24. PGE641 2.0.10 will go into use for NPP when the C2 reprocessing reaches the leading edge, which is anticipated to be 8/30/24. |
| Status | Major algorithm development completed. Sadashiva Devadiga approved 08/20/2024. Sudipta Sakar implemented 08/20/2024. |
