| Abstract | PGE511 v1.0.7-v1.0.8-v1.0.9, PGE513 v1.0.2, PGE517 v1.0.4, PGE521 v1.0.4, PGE575 v1.0.6 Update the IDPS L2 SR-IP process for operational processing at Land SIPS with MODIS LSR C6 algorithm changes Update the MODIS L2G, L2G-lite, L3 8-day composite and daily CMG PGEs with changes to read, and process the input VIIRS product in HDF4 or HDF5 format, and generate the output product in HDF4 or HDF5 format. |
| Problem Statement | Generate the Surface Reflectance product suite (VNP09, VNP09GA, VNP09A1, VNP09H1, VNP09CMG) in the V1 forward processing and reprocessing streams at Land SIPS. |
| Description of Change | |
| Products Affected | VNP09, VNP09GA, VNP09A1, VNP09H1, VNP09CMG, VNP09CMA |
| Software Affected | PGE: PGE511 V1.0.7->V1.0.8->V1.0.9; PGE513 V1.0.2, PGE517 V1.0.4; PGE521 V1.0.4; PGE575 V1.0.6 Process: NPP_PR09, NPP_PRMGPNTR, NPP_PRMGR, NPP_PR09G, NPP_PR009A, NPP_PRCMG |
| Processing String to Receive the Change | VNP Forward Processing, VNP Reprocessing, LANCE-NRT |
| Downstream Product Effects | None of these downstreams are operational at Land SIPS at this time: VI - VNP13, LAI/FPAR - VNP15, BRDF/Albedo - VNP43 |
| Data Granules to be Used for Science Testing | Run 8-day global test generating the full suite of surface reflectance products. |
| Justification | With the MODIS C6 changes implemented in the operational L2 swath process and use of similar compositing approach employed as in the MODIS L3 processes, the VIIRS product performance is expected to be same as MODIS providing the much anticipated continuity to the products from MODIS instruments. |
| Effective Date for Implementation of Change | Completed |
| Status | Sadashiva Devadiga, C. Justice, M. Roman approved 11/01/2016. Gang Ye approved on 11/1/2016. |
