The airGR package brings into the R software the hydrological modelling tools used at Irstea-HBAN (France), including GR4H, GR4J, GR5J, GR6J, GR2M, GR1A and CemaNeige. 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) are coded in R.

The airGR package has been designed to fulfil two major requirements: facilitate the use by non-expert users and 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.



For more information and to getting started with the package, you can go on the airGR website.



airGR is available on the Comprehensive R Archive Network (CRAN).
