Casi data are routinely provided in units that are directly related to spectral radiance, but for many purposes it is necessary to convert these data to reflectance. There are several methods to achieve this, which vary in their complexity, accuracy, and requirements for resources. This paper reviews two practical methodologies for the conversion of casi radiance data to reflectance. The first is based on the use of the Incident Light Sensor (ILS) fitted to the roof of the aircraft. The second uses ground calibration targets of known, stable reflectance.

Abstract
Casi data are routinely provided in units that are directly related to spectral radiance, but for many purposes it is necessary to convert these data to reflectance. There are several methods to achieve this, which vary in their complexity, accuracy, and requirements for resources. This paper reviews two practical methodologies for the conversion of casi radiance data to reflectance. The first is based on the use of the Incident Light Sensor (ILS) fitted to the roof of the aircraft. The second uses ground calibration targets of known, stable reflectance.
