Abstract | PGE504 v1.0.5 -- Port the operational IDPS AOT IP algorithm for use in operational processing of VIIRS AOT IP swath product, VNP04_L2, at Land SIPS and implement C6 changes from the internal AOT process in the C6 MODIS surface reflectance algorithm. |
Problem Statement | Generate the AOT product as an intermediate product in the land V1 forward processing and reprocessing streams at Land SIPS for use by the land surface reflectance process. |
Description of Change | Port the operational IDPS AOT IP algorithm for use in operational processing of VIIRS AOT IP swath product, VNP04_L2, at Land SIPS and implement C6 changes from the internal AOT process in the C6 MODIS surface reflectance algorithm. |
Products Affected | VNP04_L2 |
Software Affected | PGE504 v1.0.5 |
Processing String to Receive the Change | VNP Forward Processing, VNP Reprocessing, LANCE-NRT |
Downstream Product Effects | Expected to improve the aerosol correction in the L2 swath surface reflectance product VNP09 and in turn all the downstream daily and 8-day composite products. VNP09GA, VNP09A1, VNP09H1, VNP09CMG VMP09CMA |
Data Granules to be Used for Science Testing | Run 8-day global test generating the AOTIP product and the full suite of surface reflectance products. |
Justification | The upstream AOT IP process with the MODIS C6 changes generates high quality AOT IP product which in turn improves the quality and accuracy L2 LSR product. |
Effective Date for Implementation of Change | Completed |
