There are two categories of participant: existing CKD models with a fixed number of bands and spectral intervals, and CKD tools, which generate new CKD models with some control over the accuracy, efficiency (i.e. total number of spectral intervals) and range of applicability (e.g. gases treated and range of concentrations supported). The main purpose of CKDMIP is to evaluate and improve the way that CKD tools generate CKD models.
This page lists the participants so far...

CKD tools
The entries in the final three columns link to results of the evaluation of each CKD tool against line-by-line reference calculations. The FTP site contains all files from which the plots have been produced.

CKD models
Entries under the "LW statusresults summary" and "SW statusresults summary" columns indicate versions of the datasets that have been uploaded and are present on the FTP site, and the links take you to a page summarizing the evaluation against line-by-line reference calculations.
