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

Multiyear On-Orbit Calibration and Performance of Terra MODIS Thermal Emissive Bands [PDF]

IEEE Transactions on Geoscience and Remote Sensing, 2008
Since its launch in December 1999, Terra MODIS has been making continuous Earth observations for more than seven years. It has produced a broad range of land, ocean, and atmospheric science data products for improvements in studies of global climate and environmental change.

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

Proceedings of SPIE, 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.

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 ...

Electronic crosstalk in Terra MODIS thermal emissive bands

SPIE Proceedings, 2015
The MODerate-resolution Imaging Spectroradiometer (MODIS) is a legacy Earth remote sensing instrument in the National Aeronautics and Space Administration (NASA) Earth Observing System (EOS). The first MODIS instrument was launched in December 1999 on board the Terra spacecraft.

Aqua MODIS Thermal Emissive Band On-Orbit Calibration, Characterization, and Performance [PDF]

IEEE Transactions on Geoscience and Remote Sensing, 2009
The NASA's Earth Observing System Aqua Moderate Resolution Imaging Spectroradiometer (MODIS) has continued to operate with satisfactory performance since its launch in May 2002, exceeding its nominal six-year design lifetime. Its continuous Earth observations have been used to generate many science data products for studies of the Earth's system. MODIS

Terra and Aqua MODIS Thermal Emissive Bands On-Orbit Calibration and Performance

IEEE Transactions on Geoscience and Remote Sensing, 2015
Since launch, the Moderate Resolution Imaging Spectroradiometer (MODIS) instruments on the Terra and Aqua spacecraft have operated successfully for more than 14 and 12 years, respectively. A key instrument for National Aeronautics and Space Administration Earth Observing System missions, MODIS was designed to make continuous observations for studies of

Thermal emission of InAs induced by band tails

Semiconductor Science and Technology, 1994
The band tail effect on the thermal emission (TE) integrated power and the spectral distribution ( lambda =3-5 mu m) in n-InAs (Nd-Na=1.6*1016 cm-3) has been investigated for the first time. The Urbach parameter Teff has been determined in the temperature range 310-400 K. Some practical uses for the results obtained are also discussed.

MODIS thermal emissive band detector bias

SPIE Proceedings, 2009
Two nearly identical MODIS instruments are currently operating in space: one on the Terra spacecraft launched in December 1999 and another on the Aqua spacecraft launched in May 2002. MODIS has a total of 36 spectral bands, 16 of which are the Thermal Emissive Bands (TEB) with wavelengths covering from 3.7μm to 14.4μm.

Performance of MODIS thermal emissive bands on-orbit calibration algorithm

2009 IEEE International Geoscience and Remote Sensing Symposium, 2009
MODIS has 16 thermal emissive bands (TEB) covering wavelengths from 3.75 to 14.24μm. They are calibrated on a scan-by-scan basis using a quadratic calibration algorithm and data collected from detector responses to the instrument on-board blackbody (BB) and space view (SV).
