MODIS Version 6 Forward Processing Ends February 15, 2023
Posted: Tue Feb 07, 2023 10:12 am America/New_York
Version 6 (V6) forward processing of Terra and Aqua MODIS land data products will be discontinued on February 15, 2023. The V6 land data products have always suffered from known calibration issues that were discovered by the instrument Cal/Val team after the completion of the V6 reprocessing. The main among these being the increased impact of optical crosstalk in the Terra photovoltaic (PV) long-wave infrared (LWIR) bands 27-30, that had made retrieval of most atmospheric parameters infeasible, indirectly impacting some of the land products that were dependent on these atmospheric retrievals. MODIS Version 6.1 (V6.1) corrects for the optical crosstalk issue and some other critical calibration concerns. The newer version of MODIS data products also have a number of product specific improvements and enhancements that are listed in the Version 6.1 change document.
Given the improved performance and calibration of MODIS V6.1, users are requested to switch to V6.1 for all of their MODIS land data needs. LP DAAC will retain the V6 historical land data products for distribution for a period of 6 months following the end of the forward processing. All MODIS V6 land data products will be decommissioned after the expiry of this 6-month retention period.
Please contact LP DAAC User Services with any questions or concerns.
