MODIS Collection 5 data products will no longer be produced after the end of March 2017. Collection 6 data products were introduced in 2012 and are available for the entire mission record for both Terra and Aqua MODIS.

Congratulations to the members of the MODIS Characterization Support Team on receiving the 2015 NASA Group Achievement Award "for 20 years of expert and dedicated characterization of MODIS instruments on Terra and Aqua leading to unprecedented achievement in understanding Earth processes."
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:

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).
Calibration
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.
