**airGR** is a package that brings into the [**R software**](https://cran.r-project.org/) the hydrological modelling tools used and developed at the [Catchment Hydrology Research Group](https://webgr.inrae.fr/en/home/) at [INRAE (France)](https://www.inrae.fr/en), including the [**GR rainfall-runoff models**](https://webgr.inrae.fr/en/models/) and a snowmelt and accumulation model, [**CemaNeige**](https://webgr.inrae.fr/en/home/models/snow-model/). Each model core is coded in **Fortran** to ensure low computational time. The other package functions (i.e. mainly the calibration algorithm and the efficiency criteria calculation) are coded in **R**.

The **airGR** package has been designed to fulfill two major requirements: to facilitate the use by non-expert users and to allow flexibility regarding the addition of external criteria, models or calibration algorithms. The names of the functions and their arguments were chosen to this end. **airGR** also contains basics plotting facilities.
