Data on the climate data factory are derived from the original model data available on the official IPCC data portal (ESGF). These data went through a light (Raw data) or advanced processing (Ready to use data). A summary of the processing is presented in this article ; for more details, download the full technical report available on researchgate.
Short description of the processing chain
- Original data: searching and downloading original model data from the ESGF archive
- Input quality control: checking integrity of original data
- Remapping : interpolating data on a common grid
- Bias-adjustment: adjusting variables to observations for synoptic biases
- Standardization: rewriting files according to climate community’ standards
- Output quality control: checking bias-adjusted variables and metadata
- File merging: linking together the multiple 10 years data files into a unique 150 years set
- Spatial extraction: producing country and city level data sets instead of global ones
