As of February 25th, 2023, C6 Forward processing of Terra and Aqua MODIS Land data products has been discontinued, due to calibration issues that were discovered after the completion of the C6 reprocessing. The Collection 6.1 (C61) corrects these calibration issues and has a number of product specific improvements and enhancements that are listed in the C61 change document here. Given the improved performance and calibration of C61, users are requested to switch to C61 for all of their MODIS land data needs. NSIDC will retain the C6 historical land data products for a further period of 6 months, following this decommissioning of the C6 forward processing, and will decommission all C6 land data products after the expiry of this 6-month retention period.
