Estimation of Detector Biases in MODIS Thermal Emissive Bands

IEEE Transactions on Geoscience and Remote Sensing, 2013
The combination of multiple detectors and a double-sided mirror in the Moderate Resolution Imaging Spectroradiometer (MODIS) introduces striping in the imagery despite the use of onboard calibration systems. This results in a sharp unidirectional pattern across scan lines and leads to significant radiometric uncertainties in level-1 radiances, which ...

Crosstalk Effect in NOAA 20 VIIRS Thermal Emissive Bands

IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020
Crosstalk contamination in the Moderate Resolution Imaging Spectroradiometer (MODIS) thermal emissive bands (TEBs) has been a known issue since prelaunch, that has amplified on-orbit for some of bands. A linear algorithm has been developed and successfully applied to mitigate the crosstalk effect and restore the quality and accuracy of the MODIS L1B ...

Early Calibration and Performance Assessments of NOAA-20 VIIRS Thermal Emissive Bands

IEEE Transactions on Geoscience and Remote Sensing, 2019
The Visible Infrared Imaging Radiometer Suite (VIIRS) sensor aboard the NOAA-20 (previously JPSS-1) spacecraft has successfully operated since its launch in November, 2017. Similar to the first VIIRS instrument on the Suomi-National Polar-orbiting Partnership (SNPP) spacecraft, the data are collected in 22 spectral bands that are calibrated by a set of

Comparison of the MODIS and VIIRS Thermal Emissive Band Radiometric Calibration

IEEE Transactions on Geoscience and Remote Sensing, 2020
Moderate Resolution Imaging Spectroradiometer (MODIS) and Visible Infrared Imaging Radiometer Suite (VIIRS) are major instruments for Earth science observations. Nearly 40 MODIS scientific products and a wide range of VIIRS environmental data records are produced using their global observations. The consistency of the MODIS and VIIRS calibrated data is

Assessment of MODIS Thermal Emissive Band On-Orbit Calibration

IEEE Transactions on Geoscience and Remote Sensing, 2011
Sixteen Moderate Resolution Imaging Spectroradiometer thermal emissive bands (TEBs) cover the wavelength from 3.75 to 14.24 μm. TEB calibration uses data collected from the detector responses to the onboard blackbody (BB) and space view. The BB was designed to operate either at a constant temperature for detector linear gain calibration or at ...

Long-term band-to-band calibration stability of MODIS thermal emissive bands

SPIE Proceedings, 2013
The Terra and Aqua MODIS instruments have operated continuously for over 12 and 10 years respectively and are key contributors to the NASA Earth Observing System mission. The calibration for the 16 thermal emissive bands (TEB) is maintained on-orbit through scan-by-scan observations of a temperature controlled blackbody and deep space.
