Terra experienced an anomaly for B36/D7 beginning on 2014109.1405. Unlike previous instances of this unknown electronics/formatter anomaly, the detector behavior has not returned to normal.After 2 weeks continually being in the anomaly state, the decision was made to change the QA flag for this detector from 'Noisy' to 'Inoperable'. All Band 36 detectors are currently flagged as Noisy.

This QA change will be in effect from the LUT versions 5.0.46.73 (Collection 5) and 6.1.14.26 (Collection 6)

May 4, 2014 marked the 12 year anniversary of Aqua launch. The MODIS instrument on-board the Aqua spacecraft has well surpassed its design lifetime, but continues to provide valuable datasets for studies of Earth's land, ocean and atmosphere systems.

MCST arranged a workshop (via telecon) to discuss the status, impact on science products and way forward in regards to the Aqua CFPA temperature issue. The presentation can be found in the following location: https://mcst.gsfc.nasa.gov/mcst-meetings

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.

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
