# The Theory Behind KrigR

## Climate Reanalyses

Climate reanalyses are the go-to data products for climate scientists and represent the best-in-class approximations of climate characteristics across the Earth.

The accuracy of climate reanalyses is largely owed to the number of observations assimilated, the underlying dynamical model, and the data assimilation methodology. Furthermore, climate reanalyses offer access to a vast array of Essential Climate Variables (ECVs) at unparalleled temporal resolutions. Lastly, as reanalyses are created from multiple models (i.e. ensembles), we can obtain data uncertainty for each data record.

To our mind, this makes climate reanalyses the gold standard in climate data products for use in macroecological analyses.

## The KrigR Package

The KrigR package has been designed to overcome the major stop-gaps in integrating climate reanalyses data into our research frameworks:
