Latest News

Following several science tests and meetings with representatives from the science user community, the updated RVS algorithm for Aqua MODIS bands 1-4 is now in forward production. The change was implemented starting with granule 2016209.0000 (July 27, 2016 00h:00m:00s). This change removes the need for de-trending corrections, previously applied to Land products. Land products should not see a change in the data trends. Atmospheric products that include inputs from these bands may see a step change at the implementation time.

Aqua MODIS data processing experienced issues from August 8-9, 2016 related to one of the on-board clocks resetting. The issue has been resolved and previously affected data is now available. Please see the link below for more information:

Please see the attached document, which describes the timeline of the Terra safehold event and the Terra MODIS recovery to science mode. The MODIS Characterization Support Team (MCST) delivered updated calibration coefficients/parameters on 03/17/2016. They continue to monitor Terra MODIS data and telemetry.

MODIS Characterization Support Team

The MODIS Characterization Support Team (MCST) is dedicated to the production of a high quality MODIS calibration product. This product is a precursor to every geophysical science product. MCST works for the Science Team Leader and is responsible for developing and maintaining the calibration product (L1B algorithm).

Collection 6 has been under development for a number of years. MCST, in consultation with representatives of the science disciplines, developed improvements to the calibration algorithms and methodolgies to handle known issues with the aging MODIS sensors. Summary talks of the proposed Collection 6 changes have been delivered at the MODIS science team meetings over the last few years.

L1B

Current L1B LUT Versions:

Terra C6: 6.1.26.85; Terra C6.1: 6.2.2.107; Aqua C6: 6.1.37.88; Aqua C6.1: 6.2.3.32
