Three types model outputs are offered by NWPCs
Model Output Location Time Series (MOLTS) at the reference sites: high temporal resolution time-series output
Gridded Output from operational global and regional prediction models
Output from global and regional reanalysis
Eight Numerical Weather Prediction Centers (NWPCs), NCEP, UKMO, ECMWF, JMA, CPTEC, BoM, ICMWF, ECPC, and two Data Assimilation Center, NASA/GMAO, NASA/GSFC provide model outputs to CEOP, and CEOP offers a globally consistent data sets for model validation and calibration.

Assessment of land models in coupled models is hindered bysurface forcing errors in parent atmospheric model, such as biasesin precipitation and solar insolation.
Figures at right show high bias inthe global model’s monthly mean diurnal cycle of surface solarinsolation during J ul 2001compared to observations at 3 CEOP sites:
