The MODIS Characterization Support Team (MCST) is dedicated to the production of a high quality MODIS calibration product. MCST developed the L1B algorithm and all parameters necessary to run the code, and develops the quality assurance and verification of L1B product enhancements. The MCST flight operations team supports MODIS operations on orbit through command and control of the instrument. Responsibilities include developing MODIS operations scenarios, creating the operations database, monitoring instrument health and safety, and operating the MODIS on-orbit.
The purpose of the MODIS Instrument Operations Team (IOT) is to plan, schedule, and monitor MODIS activities. The MODIS Instrument Operations Team schedules a daily set of Operational Activities using the Instrument Support Toolkit (IST) software package provided by the EOS Flight Operations Segment.
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).
Last night (2/22/2016) the Terra FOT successfully recovered the Terra spacecraft from Safe-Mode back to Normal mode. A Command Authorization Meeting (CAM) was scheduled this morning (02/23/2016) to review the plan to recover the MODIS instrument. The recovery of the MODIS instrument is currently in progress. Updates will be posted periodically.
Terra spacecraft entered safe mode (2016/049: 14:33:17) during an IAM. This caused MODIS to enter safe mode as well. The nadir and the space-view doors are closed as expected. The solar diffuser door is still open (since the anomaly from July, 2003). Updates will be posted periodically.
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: http://mcst.gsfc.nasa.gov/mcst-meetings
Terra experienced an anomaly for B36/D7 beginning on 2015092.1740. 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.
MODIS (or Moderate Resolution Imaging Spectroradiometer) is a key instrument aboard the Terra (EOS AM) and Aqua (EOS PM) satellites. Terra's orbit around the Earth is timed so that it passes from north to south across the equator in the morning, while Aqua passes south to north over the equator in the afternoon. Terra MODIS and Aqua MODIS are viewing the entire Earth's surface every 1 to 2 days, acquiring data in 36 spectral bands, or groups of wavelengths (see MODIS Technical Specifications).
These data will improve our understanding of global dynamics and processes occurring on the land, in the oceans, and in the lower atmosphere. MODIS is playing a vital role in the development of validated, global, interactive Earth system models able to predict global change accurately enough to assist policy makers in making sound decisions concerning the protection of our environment.
MODIS was launched on the EOS Aqua spacecraft on Saturday, May 4, 2002 at 09:55 GMT. MODIS Aqua "First Light" was achieved when the MODIS Nadir Aperture Door opened on June 24, 2002 at 23:22:48 GMT. The Aqua MODIS instrument began taking data using side-B electronics. For a complete look at the EOS-PM/ Aqua mission, see http://aqua.nasa.gov/.
MODIS was launched on the EOS Terra spacecraft on Saturday, December 18, 1999 at 18:57 GMT. MODIS Terra "First Light" was achieved when the MODIS Nadir Aperture Door opened on February 24, 2000. The Terra MODIS instrument began taking data using side-A electronics. For a complete look at the EOS-AM/ Terra mission, see http://terra.nasa.gov/.
