Notice to Terra Data Users

Dec
02

The reflective solar bands (RSB) of Terra MODIS have experienced relatively large degradation in recent years. The current calibration algorithm used in deriving the Collection 5 LUTS does not completely capture and correct for this degradation, which is both wavelength and angle-of-incidence dependent. Science data products that utilize the shorter wavelength bands, especially Bands 8 (412 nm), 9 (443 nm) 3 (469 nm), 1 (646 nm), and 2 (856 nm) can expect to see an observable impact on data quality.

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.
