One year after the first meeting in Paris, the CNES, the LATMOS and the STCE are happy to invite you at the second edition of the meeting "Solar Metrology, Needs and Methods". This meeting is open to anyone involved in solar metrology and modelling. It intends to review the recent progresses in those two fields, to analyze the possibilities, but also the limitations of the current ground- or space-based observation facilities, and to discuss the major challenges for future missions.
