CERES Radiation Fluxes for CMIP5



This data set is only available for a restricted user group, please contact us if you want to access these data.

RESTRICTED only accessable in CEN/MPI net or via CliSAP login  What does that mean?

View data via LAS

Access data via OPeNDAP

Data access via file system: /data/icdc/atmosphere/ceres_cmip5



This is a subset o the CERES data set which has been prepared such that it can be easily compared to CMIP5 Model runs. More information about CERES data is given on our CERES webpage, on the respective NASA webpage and in the references.

This is Version Ed2.7 of the CERES-EBAF Products, downloaded Februar 04, 2014.
