CHFP Data Archive
Welcome to the CHFP Data Archive Page. Here you will find guidance on preparing, serving and using data from the Climate-system Historical Forecast Project. Please read the relevant guide(s) before starting work, and please provide feedback on these web pages to Anna.Pirani@noc.soton.ac.uk. Note that these pages are still in an early stage of development, and the data conventions described are still subject to possible change.
Access CHFP data from:
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."

- CHFP_variable_names
- Example script - data retrieval
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.
Example scripts to generate the correct format data for the CIMA server, according to the CHFP protocol (by Dughong Min, RSMAS):
