Vicarious calibration campaign in Argentina for radiometric calibration of a multispectral imager onboard sumbandila satellite

Abstract

Continuous assessment of the radiometric response of Earth Observation (EO) satellite imagers is necessary for the quality assurance of derived data products. With the launch of South Africa’s SumbandilaSat in September 2009, a number of vicarious calibration campaigns have been planned and executed to meet this requirement for the high-resolution multispectral imager payload. This paper describes a vicarious calibration campaign executed in Argentina in October 2010. A number of salt pans in Argentina were visited and characterised during this campaign. SumbandilaSat images of two of the sites were captured simultaneously with in situ measurements.
