Aqua MODIS band 21 QA

Feb
27

After the recent Aqua BB WUCD on 01/31/2015 it was observed that 3 detectors (2, 3,& 9) for band 21 experienced a b1 jump and NEdT increase. The increased NEdT is greater than the specification and has been consistent for over two weeks. MCST procedure dictates a QA LUT update for these detectors to ‘Noisy’ status. This update will be included in the next regular Aqua LUT delivery. The timestamp for the QA change will be 2015031.2100.

Terra Science Formatter Equipment (SFE) Anomaly

Oct
30

SFE Anomaly: After passage through the SAA on 2014/299 ~01:35 EDOS observed corrupted MODIS data. The cause was traced to a formatter card that had become out of sync resulting in the corrupt data. Only MODIS data is processed by this card so no other instruments were affected. FOT successfully reset the card and returned data flow to nominal operation. Expect a data loss from 2014/299 01:35:00 – 18:47:00. Exact loss time still to be confirmed by FOT.

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. Please see the major changes implemented in MODIS Collection 6 LUTs as compared with Collection 5 LUTs.

L1B

Current L1B LUTs: Terra: Version 5.0.46.87 Aqua: Version 5.0.41.38
