The goal of climaemet is to serve as an interface to download the climatic data of the Spanish Meteorological Agency (AEMET) directly from R using their API and create scientific graphs (climate charts, trend analysis of climate time series, temperature and precipitation anomalies maps, “warming stripes” graphics, climatograms, etc.).

AEMET OpenData is a REST API developed by AEMET that allows the dissemination and reuse of the Agency’s meteorological and climatological information. To see more details visit: https://opendata.aemet.es/centrodedescargas/inicio
Information prepared by the Spanish Meteorological Agency (© AEMET). You can read about it here.
A summary for the usage of the data could be interpreted as:
People can use freely this data. You should mention AEMET as the collector of the original data in every situation except if you are using this data privately and individually. AEMET makes no warranty as to the accuracy or completeness of the data. All data are provided on an “as is” basis. AEMET is not responsible for any damage or loss derived from the interpretation or use of this data.
You can install the released version of climaemet from CRAN with:
install.packages("climaemet")You can install the developing version of climaemet using the r-universe:
# Install climaemet in R:
install.packages("climaemet",
repos = c("https://ropenspain.r-universe.dev", "https://cloud.r-project.org")
)Alternatively, you can install the developing version of climaemet with:
# install.packages("pak")
pak::pak("ropenspain/climaemet")To be able to download data from AEMET you will need a free API key which you can get here.
library(climaemet)
## Get api key from AEMET
browseURL("https://opendata.aemet.es/centrodedescargas/obtencionAPIKey")
## Use this function to register your API Key temporarly or permanently
aemet_api_key("MY API KEY")Now the apikey parameter on the functions have been deprecated. You
may need to set your API Key globally using aemet_api_key(). Note that
you would need also to remove the apikey parameter on your old codes.
From v1.0.0 onward, climaemet provides its results in tibble
format. Also, the functions try to guess
the correct format of the fields (i.e. something as a Date/Hour now is
an hour, numbers are parsed as double, etc.).

#> # stddv <dbl>, inso <dbl>, tss5cm <dbl>, pacutp <dbl>, tss20cm <dbl>Another major change in v1.0.0 is the ability of return information on
spatial sf format, using return_sf = TRUE. The coordinate reference
system (CRS) used is EPSG 4326, that correspond to the World
Geodetic System (WGS) and return coordinates in latitude/longitude
(unprojected coordinates):
# You would need to install `sf` if not installed yet
# run install.packages("sf") for installation
library(ggplot2)
library(dplyr)
all_stations <- aemet_daily_clim(
start = "2021-01-08", end = "2021-01-08",
return_sf = TRUE
)
ggplot(all_stations) +
geom_sf(aes(colour = tmed), shape = 19, size = 2, alpha = 0.95) +
labs(
title = "Average temperature in Spain",
subtitle = "8 Jan 2021",
color = "Max temp.\n(celsius)",
caption = "Source: AEMET"
) +
scale_colour_gradientn(
colours = hcl.colors(10, "RdBu", rev = TRUE),
breaks = c(-10, -5, 0, 5, 10, 15, 20),
guide = "legend"
) +
theme_bw() +
theme(
panel.border = element_blank(),
plot.title = element_text(face = "bold"),
plot.subtitle = element_text(face = "italic")
)
We can also draw a “warming stripes” graph with the downloaded data from a weather station. These functions returns ggplot2 plots:
# Plot a climate stripes graph for a period of years for a station
library(ggplot2)
# Example data
temp_data <- climaemet::climaemet_9434_temp
ggstripes(temp_data, plot_title = "Zaragoza Airport") +
labs(subtitle = "(1950-2020)")
Furthermore, we can draw the well-known Walter & Lieth climatic diagram for a weather station and over a specified period of time:
# Plot of a Walter & Lieth climatic diagram for a station
# Example data
wl_data <- climaemet::climaemet_9434_climatogram
ggclimat_walter_lieth(wl_data,
alt = "249", per = "1981-2010",
est = "Zaragoza Airport"
)
Additionally, we may be interested in drawing the wind speed and direction over a period of time for the data downloaded from a weather station.:
# Plot a windrose showing the wind speed and direction for a station
# Example data
wind_data <- climaemet::climaemet_9434_wind
speed <- wind_data$velmedia
direction <- wind_data$dir
ggwindrose(
speed = speed, direction = direction,
speed_cuts = seq(0, 16, 4), legend_title = "Wind speed (m/s)",
calm_wind = 0, n_col = 1, plot_title = "Zaragoza Airport"
) +
labs(subtitle = "2000-2020", caption = "Source: AEMET")
