Introduction to the climate package

2022-02-22

The goal of the climate R package is to automatize downloading of meteorological and hydrological data from publicly available repositories:

Functions

The climate package consists of ten main functions - three for meteorological data, one for hydrological data and six auxiliary functions and datasets:

Meteorological data

Hydrological data

Auxiliary functions and datasets

Examples

Examples shows aplication of climate package with additional use of tools that help with processing the data to increase legible of downloaded data.

Example 1

Finding a 50 nearest meteorological stations in a given country:

library(climate)
ns = nearest_stations_ogimet(country ="United+Kingdom",
                             point = c(-4, 56),
                             no_of_stations = 50, 
                             add_map = TRUE)
