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.

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 ...

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.

Use of external solar spectra to multispectral sensor systems as an alternative for radiometric correction and calibration of ToA reflectance [PDF]

Most Earth observation satellite missions do not have instruments to measure solar irradiance in orbit. Consequently, the temporal variability of the recorded reflectance is based only on the radiance measured by the sensor, since the incident solar ...

HYPERNETS: a network of automated hyperspectral radiometers to validate water and land surface reflectance (380–1680 nm) from all satellite missions

Frontiers in Remote Sensing
Satellites are now routinely used for measuring water and land surface reflectance and hence environmentally relevant parameters such as aquatic chlorophyll a concentration and terrestrial vegetation indices.

Applying principles of metrology to historical Earth observations from satellites [PDF]

, 2019
Approaches from metrology can assist Earth Observation (EO) practitioners to develop quantitative characterisation of uncertainty in EO data. This is necessary for the credibility of statements based on Earth observations in relation to topics of public ...

The Characterization of the Railroad Valley Playa Test Site Using the DESIS Imaging Spectrometer from the Space Station Orbit

Remote Sensing
The reflectance-based vicarious calibration approach uses measurements at well-understood test sites to provide top-of-atmosphere reference reflectance values suitable for inter-calibration approaches and does not require coincident views.
