CHFP Data Server at CIMA

The CHFP data set is being hosted by the Centro de Investigaciones del Mar y la Atmósfera (CIMA), Argentina. The CHFP dataset is open and free for non-commercial purposes. After registering anyone can obtain the model output.

Please use the following acknowledgment when using CHFP data:

"We acknowledge the WCRP/CLIVAR Working Group on Seasonal to Interannual Prediction (WGSIP) for establishing the Climate-system Historical Forecast Project (CHFP, see Kirtman and Pirani 2009) and the Centro de Investigaciones del Mar y la Atmosfera (CIMA) for providing the model output http://chfps.cima.fcen.uba.ar/. We also thank the data providers for making the model output available through CHFP."

Support documents to archive and retrieve CHFP data

CHFP netCDF specification:

Data is provided in netCDF via THREDDS or OpenDAP servers. In most cases aggregation servers are used, and data retrievals from a single data host will typically contain output from multiple models.

It is recommended that participants send CIMA a test file to address any technical issues before transferring the full data set.
