cfr` aims to provide a universal framework for climate field reconstruction (CFR).
It provides a toolkit for
+ the processing and visualization of the proxy records, climate model simulations, and instrumental observations,
+ the calibration and running of the proxy system models (PSMs, [Evans et al., 2013](https://doi.org/10.1016/j.quascirev.2013.05.024)),
+ the preparation and running of the multiple reconstruction frameworks/algorithms, such as LMR ([Hakim et al., 2016](https://doi.org/10.1002/2016JD024751); [Tardif et al., 2019](https://doi.org/https://doi.org/10.5194/cp-15-1251-2019)) and GraphEM ([Guillot et al., 2015](https://doi.org/10.1214/14-AOAS794)), and
+ the validation of the reconstructions, etc.
