Method of Vicarious Calibration of the Kanopus-V Satellite Constellation Data Based on Long-Term Observation of RadCalNet Polygons

Rocket-space device engineering and information systems, 2021
The article discusses a method of vicarious data calibration of the MSS sensor of the Kanopus-V spacecraft based on the observation of RadCalNet polygons in the 2018–2020 period. The technique includes the stage of processing ground-based RadCalNet measurements for the period, with the aim of analytical approximation of the time series to ensure its ...

Retrieval of Aerosol and Surface Properties at High Spatial Resolution: Hybrid Approach and Demonstration Using Sentinel‐5p/TROPOMI and PRISMA

Journal of Geophysical Research: Atmospheres, Volume 129, Issue 15, 16 August 2024.
Abstract Satellite remote sensing of aerosol is largely conducted at moderate or coarse spatial resolution around 1–10 km. Nevertheless, at urban areas with high human activity, aerosol can originate from complex emission sources and may also vary strongly in space.

Calibrating Geosynchronous and Polar Orbiting Satellites: Sharing Best Practices

Remote Sensing, 2020
Earth remote sensing optical satellite systems are often divided into two categories—geosynchronous and sun-synchronous. Geosynchronous systems essentially rotate with the Earth and continuously observe the same region of the Earth.
