Abstract

The development of science quality miniature payloads for nano satellites has facilitated the implementation of private observatories and even constellations of satellites for all sort of applications. GRASP Earth is currently developing a payload system composed of a multi-angle imaging polarimeter for the measurement of aerosol pollution and a high-resolution spectrometer for the measurement of greenhouse gases like CO2 and CH4, with commercial applications. Based on these measurements the GRASP (Generalized Retrieval of Atmosphere and Surface Properties, https://www.grasp-sas.com/) algorithm can simultaneously retrieve detailed details on the aerosol microphysics including particle size, refractive indices, particle sphericity, and the particle absorption properties, as well as the concentration of the greenhouse gases. These measurements performed from a single platform, and the joint aerosol and gases retrieval by GRASP produces higher accuracy and better sensitivity than each measurement perform independently.
