Description:

The observation of the atmosphere based on passive/active remote-sensing and in situ measurements are mature to be exploited for the evaluation of models. Since many years, the ground-based atmospheric observatory such as the SIRTA (Site Instrumenté de Recherche par Télédétection Atmosphérique), Cabauw, and Chilbolton (all part of CLOUDNET) have been collecting many collocalized observations which can be used in order to analyse the interannual variability of the atmospheric column and to evaluate the parameterization included in models (objectives of the European project EUCLIPSE).

To make these data easily usable, important work has been implemented on their homogenization. All variables, their description, their quality flags, their spatiotemporal error-bars are written in a single file (NetCDF). Similar algorithms are applied to the three sites. Four files are produced: one by site (i.e. 3 files) for the EUCLIPSE time-period (January 2008 to April 2010) and variables required by CMIP-5, and one more file for the SIRTA with additional variables and a longer time-period (2002 to 2010, SCTD file).
