Targeted User Communities

Global and regional climate trends and variability analysis

high quality Climate Data Records (CDR) are expected e.g. for climate studies in contribution to IPCC.

Thematic Climate Data Records (TCDR) from CM SAF will provide consistent information on Essential Climate Variables (ECV) related to the global energy and water cycle supporting closure studies


Support to global and regional climate modelling use of Climate Data Records for model evaluations, feedback studies, and

uncertainty studies these datasets needed at high(er) temporal and spatial resolutions most recent satellite instrument, only cover short time periods.
