MODIS C7 Reprocessing Plan Sadashiva Devadiga NASA GSFC May 1-4, 2023 MODIS VIIRS Science Team Meeting 1
Outline C61 Processing history C7 and Beyond Time line C7 L1, Atmosphere and Land May 1-4, 2023 MODIS VIIRS Scince Team Meeting 2
C61 Processing history L1B reprocessing (3 6 months) Terra 06/2017 08/2017 Aqua 12/2017 03/2018 Atmosphere ( 6+ months) Terra 07/2017 12/2017 Aqua 01/2018 03/2018 Land (~ 24 months) Terra and Aqua (Tier1): 02/2020 12/2021 Terra and Aqua (Tier2): 2021 in progress MAIAC to complete by May/June 2023 C62 DSR/PAR reprocessing for the full mission period (2000 2023) to start in May 2023, expected to complete by Dec 2023. May 1-4, 2023 MODIS VIIRS Scince Team Meeting 3
C61 Processing history Land May be 18 months or less Issues Re-reprocessing of products/temporal periods needed to address production related and science algorithm issues revealed while reprocessing is in progress. Production system shutdown for periodic maintenance and system upgrades Production system problems, production database performance, export backlog Some of these needed to be transitioned to Ubuntu OS prior to start of reprocessing May 1-4, 2023 MODIS VIIRS Scince Team Meeting 4
C7 and Beyond C7 target start (Best Scenario) L1B: early 2024 Atmosphere: Spring or Summer 2024 Land: Fall 2024 End of Mission processing (Phase F) Depends on Senior Review outcome Funding Scenarios for science team Mission decommission timeline C7.1 (only calibration change)/C8 (calibration + discipline science) reprocessing Start in early 2026 May 1-4, 2023 MODIS VIIRS Scince Team Meeting 5
C7: L1 All calibration changes and LUT are in place many of these changes are already in C61 forward processing Science Test in progress for atmosphere, test for land team expected to start in June. Target start date for L1 collection reprocessing is early 2024 Schedule drivers How much of downstream tests required (land and atmosphere) Still to come Required geolocation change, land water mask Optional any post process that usually run with L1 (e.g. subset to Langley RC) Impact from Orbital drift is expected to be minimal or none, calibrated products are expected to be nominal May 1-4, 2023 MODIS VIIRS Scince Team Meeting 6
C7: Atmosphere Algorithm change development in progress at SCF Integration Test in progress at MODAPS for some of the PGEs. Target start date Summer 2024 Schedule drivers Need for availability of C7 L1 Number of algorithm changes and complexity Deviation from the current algorithm structure and use of new libraries Delivery schedule Product interdependency Level of testing required at MODAPS May 1-4, 2023 MODIS VIIRS Scince Team Meeting 7
C7: Land In planning stage Product specific changes not determined yet Needs Polarization Correction based on the C7 L1B Product specific science changes need to weigh in effort/complexity vs change in product performance MODIS C7 to VIIRS C3 May 1-4, 2023 MODIS VIIRS Scince Team Meeting 8
