Suite of GR Hydrological Models for Precipitation-Runoff Modelling R package airGR version 1.7.9 CRAN Task View: Hydrology (https://CRAN.R-project.org/view=Hydrology) Hydrological modelling tools developed at INRAE-Antony (HYCAR Research Unit, France). The package includes several conceptual rainfall-runoff models (GR4H, GR5H, GR4J, GR5J, GR6J, GR2M, GR1A) that can be applied either on a lumped or semi-distributed way. A snow accumulation and melt model (CemaNeige) and the associated functions for the calibration and evaluation of models are also included. Use help(airGR) for package description and references.
