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.
