An R console utility that lets you ask R related questions to the
    'OpenAI' large language model. It can answer 'how-to()' questions by  
    providing code, and 'whatis()' questions by explaining what given code does.
    You must provision your own key for the 'OpenAI' API 
    <https://platform.openai.com/docs/api-reference>.

Tools for downloading hourly averages, daily maximums and
    minimums from each of the pollution, wind, and temperature measuring
    stations or geographic zones in the Mexico City metro area. The
    package also includes the locations of each of the stations and zones.
    See <http://aire.cdmx.gob.mx/> for more information.

Model that assesses daily exposure to air pollution, which considers daily population mobility on a geographical scale and the spatial and temporal variability of pollutant concentrations, in addition to traditional parameters such as exposure time and pollutant concentration.

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.

Sample of hydro-meteorological datasets extracted from the 'CAMELS-FR' French database <https://hal.inrae.fr/hal-03687235>. It provides metadata and catchment-scale aggregated hydro-meteorological time series on a pool of French catchments for use by the 'airGR' packages.

Add-on to the 'airGR' package which provides the tools to assimilate observed discharges in daily GR hydrological models. The package consists in two functions allowing to perform the assimilation of observed discharges via the Ensemble Kalman filter or the Particle filter as described in Piazzi et al. (2021) <doi:10.1029/2020WR028390>.
