Rapid A/Ci Curve Fitting Methods
Software packages publicly available for analyzing & fitting photosynthetic CO2 & light response curves
There are a number of free software resources available for CIRAS customers for analysis and fitting photosynthetic related curves on the web. Some software is designed for only gas exchange and some for both gas exchange and chlorophyll fluorescence. Some of these resources are highlighted below and we hope you find them useful. We highly suggest that users review all available resources and determine the best model to fit your data. If you discover a new model and would like to share it, we would be happy to post it here to support the scientific research community.
