Abstract PGE632 2.0.5

PGE632/Gridded GIBS code and LUTs were revised in support of NRT V*46A1 and V*46A2 products to produce Polar region GIBS images not previously generated. New products being generated included these ESDTs: V1Z46A1_NHN_DNBV1Z46A1_NHN_FCCV1Z46A1_SHN_DNBV1Z46A1_SHN_FCCVNZ46A1_NHN_DNBVNZ46A1_NHN_FCCVNZ46A1_SHN_DNBVNZ46A1_SHN_FCCVNZ46A2_NHN_ANLVNZ46A2_SHN_ANL

Problem Statement VIIRS PGE632/Gridded GIBS, was revised to support generating GIBS images for VIIRS LBAN products for polar regions, which was not included in the original version.
Description of Change PGE632/Gridded GIBS code and LUTs were revised in support of NRT V*46A1 and V*46A2 products to produce Polar region GIBS images not previously generated. New products being generated included these ESDTs: V1Z46A1_NHN_DNBV1Z46A1_NHN_FCCV1Z46A1_SHN_DNBV1Z46A1_SHN_FCCVNZ46A1_NHN_DNBVNZ46A1_NHN_FCCVNZ46A1_SHN_DNBVNZ46A1_SHN_FCCVNZ46A2_NHN_ANLVNZ46A2_SHN_ANL
Products Affected NRT V*46A1 and V*46A2 products
Software Affected PGE632 2.0.5
Processing String to Receive the Change S-NPP Forward Processing. J1 Forward Processing. NRT
Downstream Product Effects No downstream datasets are impacted by this change
Data Granules to be Used for Science Testing Science testing was conducted and datasets were reviewed by LDOPE and the GIBS team.
Justification To generate additional GIBS products, those for polar regions, for the V*46A1 and V*46A2 NRT products.
Effective Date for Implementation of Change Revised PGE632 2.0.5 was put into use for both SNPP and JPSS1, V*46A1 datasets, and SNPP VNP46A2 starting with data from 3/12/26. The JPSS1 VJ146A2 is not yet generated in nrt processing, but this GIBS PGE will be used for it once we begin to generate that dataset in NRT.
