STRATUS (SaTellite pRoducts vAlidaTion USing ground based lidar stations) is a ROSA-STAR project, ctr. 152/2017.

The STRATUS project is designed to meet EU efforts to calibrate and validate ESA earth observation programs by providing the backbone to understand and study new satellite products and to make the first steps to perform complementary measurements for validation and calibration purposes. The main goal of the project is to offer the means to validate and calibrate satellite observations by offering a wide range of ground based unbiased atmospheric products over extended time scales and monitor the stability of satellite products over the envisaged locations. The implementation of the project will help strengthening the know how in satellite validation and help build the required infrastructure to further participate to cal/val activities lead by ESA or the EU.
