Cross-Calibration of Terra and Aqua MODIS Using RadCalNet
IEEE Geoscience and Remote Sensing Letters, 2021Moderate Resolution Imaging Spectroradiometer (MODIS) instruments onboard the Terra and Aqua spacecraft have been successfully operating for nearly two decades and providing complementary observations of the Earth’s land, ocean, and atmosphere. Although the two MODIS instruments view the entire Earth’s surface once every 2–3 days, simultaneous views ...

Vicarious Radiometric Calibration of Superview-1 Sensor Using RadCalNet TOA Reflectance Product
2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021The Radiometric Calibration Network (RadCalNet) provide SI-traceable Top-of-Atmosphere (TOA) spectrally-resolved reflectance for automated radiometric calibration of optical satellite sensors. Each RadCalNet site is equipped with automated ground instrumentation in order to provide continuous measurements of both surface reflectance and local ...

Evaluation of vicarious calibration for airborne sensors using RadCalnet
Journal of Applied Remote Sensing, 2020Vicarious calibration approaches using in-situ measurements are key techniques applied to on-orbit remote sensors. The in-situ measurements have advantages in terms of traceability and quantifiable accuracy that make them ideal for inter-consistency studies of on-orbit sensors.

Ground comparisons at RadCalNet sites to determine the equivalence of sites within the network
Sensors, Systems, and Next-Generation Satellites XXI, 2017The Radiometric Calibration Network (RadCalNet, www.radcalnet.org) routinely brings together data from several instrumented ground sites to provide users with top-of-atmosphere (TOA) reflectance data. These data are provided on cloud free days between 09:00 and 15:00 for the spectral range 400 to 1000 nm (and up to 2500 nm depending on available ...

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
A new permanently instrumented radiometric calibration site for high/medium resolution imaging satellites in the visible/near-IR has been set up in Gobabeb, Namibia in July 2017. The station location has been decided after a global analysis of satellite data assessing surface spatial homogeneity, cloud coverage, temporal variability, atmospheric ...
