The LATMOS Laboratory, part of the CNRS, is involved in the PICARD project, aimed at measuring the sun diameter with a very high accuracy. These measures, made from space and from earth, should improve our knowledge about atmospheric perturbations, and the sun influence on earth climate. Thus, two telescopes, SODISM on the PICARD satellite, and its twin MISOLFA on the ground, are taking images of the sun contours.
ORME is in charge of developing an automatic analysis software application, to handle the image denoising, the precise sun contour localization, the derive correction, as well as the computation of the atmospheric perturbation parameters. On the one hand, this user-friendly software tool will enable the scientist in CNRS-LATMOS to process the huge image database. On the other hand, it offers an open architecture to test other analysis algorithms or other atmospheric perturbation models by themselves.
The first release delivery of the software application MISOLFA is planned during summer 2012.
