Simulation of satellite data<\/h1><\/div>

Space agencies have growing interests in test data for the preparation of future missions<\/strong>. The production of Level 1 data for full observing sequences and covering the diversity of natural targets allows agencies to anticipate the grounds segment exploitation in many aspects (from pixel classification to Level 2 treatments, evaluation of computer resources, etc). Furthermore, it offers to end-users the possibility to get familiar with the data format and information content. The production of TOA radiance with arbitrary spatial and spectral sampling also allows studing the information content in designing new instruments. It is also useful to assess some aspects of instruments calibration (e.g. study the impact of spectral response function mis-characterisation on Level 2 products).<\/p>\n

Thanks to its in-depth knowledge of the radiative transfer, HYGEOS has developed powerful and accurate tools. Using the satellite radiances simulator<\/strong>, SMART-G<\/a> and SMAC-CL<\/a>, HYGEOS can simulate data for any existing or future passive radiometer flying onboard polar-orbiting or geostationary Earth Observation platforms. Thus, HYGEOS offers services to:<\/p>\n
