Noise Characterization and Performance of MODIS Thermal Emissive Bands.
IEEE Trans Geosci Remote Sens
June 2016
Article Synopsis
- The MODerate-resolution Imaging Spectroradiometer (MODIS) is a key Earth observation tool on the Terra and Aqua satellites, successfully operating beyond their initial design lifespans.
- MODIS has a high duty cycle, allowing it to capture data from almost the entire Earth in under 2 days, utilizing specialized thermal bands for detailed measurements.
- The paper evaluates calibration and noise performance using various techniques, including measuring temperature stability and noise metrics, to ensure accurate data collection from the sensor's thermal emissive bands.
Assessment of S-NPP VIIRS On-orbit Radiometric Calibration and Performance.
Remote Sens (Basel)
February 2016
The VIIRS instrument on board the S-NPP spacecraft has successfully operated for more than four years since its launch in October, 2011. Many VIIRS environmental data records (EDR) have been continuously generated from its sensor data records (SDR) with improved quality, enabling a wide range of applications in support of users in both the operational and research communities. This paper provides a brief review of sensor on-orbit calibration methodologies for both the reflective solar bands (RSB) and the thermal emissive bands (TEB) and an overall assessment of their on-orbit radiometric performance using measurements from instrument on-board calibrators (OBC) as well as regularly scheduled lunar observations.
