The 1st Earth-CARE/EECLAT Joint Workshop (aka the 6th EECLAT workshop) took fflace between January 29th and 31st in Colmar, France. Below you will find the final programme (PDF). The scientific presentations can be found here.

Thanks to all participants ! Thanks to Anna Luebke for working on logistics with us and for writing a paper about the workshop ! (see below). Also thanks to the Grand Hotel Bristol which provided the infrastructure and coffee.
