Laboratoire d’Etudes du Rayonnement et de la Matière en Astrophysique et Atmosphères

The LERMA (Laboratoire d’Etudes du Rayonnement et de la Matière en Astrophysique et Atmosphères) is a joint research unit. Research teams conduct programs in the fields of astrophysics, instrumentation and remote sensing.. The 'Remote Sensing  group focuses on satellite-based characterization of the atmosphere and surfaces. Different aspects are covered, including the analysis of satellite observations, the modeling of radiative transfer and the development of inversion methods for a better monitoring of the Earth's processes providing geophysical variables (e.g. soil moisture, flood extent, emissivity) on long time series at the global scale, for use in climatology or meteorology.
