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 188.8.131.52 (Collection 5) and 184.108.40.206 (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
The MODIS Science Team Meeting will be held April 29 - May 1, 2014 at the Sheraton Columbia Town Center Hotel in Columbia, MD. Information regarding registration, logistics, and agendas is now available here: https://www.signup4.net/Public/ap.aspx?EID=MODI23E
Terra band 10 EV-based RVS: The EV-based m1 and RVS algorithm currently used for bands 8 & 9 was extended to band 10. A special LUT was delivered to OBPG for testing. The results demonstrated that the LUT produced very similar results to the correction applied by OBPG. It was recommended that the new band 10 approach be implemented in the official Collection 6 LUT. A new LUT was delivered containing this update (220.127.116.11_OC) prior to the start of an OBPG reprocessing. MCST will begin a similar implementation in the forward C6 to eventually synchronize the OBPG and forward C6 LUTs.
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.
Current L1B LUT Versions:
Terra C6: 18.104.22.168; Terra C6.1: 22.214.171.124; Aqua C6: 126.96.36.199; Aqua C6.1: 188.8.131.52
