A New 32-Day Average-Difference Method for Calculating Inter-Sensor Calibration Radiometric Biases between SNPP and NOAA-20 Instruments within ICVS Framework

Remote Sensing, 2021
Two existing double-difference (DD) methods, using either a 3rdSensor or Radiative Transfer Modeling (RTM) as a transfer, are applicable primarily for limited regions and channels, and, thus critical in capturing inter-sensor calibration radiometric bias

An approach to detect gas flaring sites using sentinel-2 MSI and NOAA-20 VIIRS images

International Journal of Applied Earth Observations and Geoinformation, 2023
Detecting gas flaring activities during oil production on a regional scale is necessary, since it emits harmful gases and bring serious global environmental impacts. This study developed a new algorithm to detect gas flare sites (GFs) on daytime Sentinel-
