Description

Niger 3 is one of 20 desert sites that were identified for optical satellite sensor calibration by Cosnefroy et al. [1], based on the <3 percent or better spatial uniformity criterion. This study found an average spatial uniformity of 2.6 percent for Niger 3. This desert site has the longest continuous stability per year [2]. 

Usability

As like other desert areas, this site has importance for different types of calibration activities for satellite sensors. This site was considered for creating and implementing cross-calibration methodologies [3].
