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](https://opendata.aemet.es/) and create scientific graphs (climate charts,
trend analysis of climate time series, temperature and precipitation anomalies
maps, "warming stripes" graphics, climatograms, etc.).

## AEMET Open Data
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:
## License for the original data
Information prepared by the Spanish Meteorological Agency (© AEMET). You can
read about it [here](https://www.aemet.es/en/nota_legal).
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.
## Installation
You can install the released version of **climaemet** from
[CRAN](https://CRAN.R-project.org) with:
```{r, eval=FALSE}
install.packages("climaemet")
```
You can install the developing version of **climaemet** using the
[r-universe](https://ropenspain.r-universe.dev/climaemet):
```{r, eval=FALSE}
# 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:
```{r, eval=FALSE}
library(remotes)
install_github("ropenspain/climaemet")
```
## API key
To be able to download data from AEMET you will need a free API key which you
can get [here](https://opendata.aemet.es/centrodedescargas/obtencionAPIKey).
```{r, eval=FALSE}
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")
```
### Changes on v1.0.0!
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.
## Now **climaemet** is tidy...
From `v1.0.0` onward, **climaemet** provides its results in [`tibble`
format](https://tibble.tidyverse.org/). 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.).
```{r tibble, message=TRUE}
library(climaemet)
# See a tibble in action
aemet_last_obs("9434")
```
### Examples
The package provides several functions to access the data of the API. Here you
can find some examples:
```{r api}
## Get AEMET stations
stations <- aemet_stations() # Need to have the API Key registered
knitr::kable(head(stations))
station <- "9434" # Zaragoza Aeropuerto
## Get last observation values for a station
data_observation <- aemet_last_obs(station)
knitr::kable(head(data_observation))
## Get daily/annual climatology values for a station
data_daily <- aemet_daily_clim(station,
start = "2022-01-01",
end = "2022-06-30"
)
knitr::kable(head(data_daily))
## Get monthly/annual climatology values for a station
data_monthly <- aemet_monthly_clim(station, year = 2022)
knitr::kable(head(data_monthly))
## Get recorded extreme values of temperature for a station
data_extremes <- aemet_extremes_clim(station, parameter = "T")
knitr::kable(head(data_extremes))
```
We can also draw a "warming stripes" graph with the downloaded data from a
weather station. These functions returns **ggplot2** plots:
```{r climatestripes, fig.asp=0.7, eval=TRUE}
# 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:
```{r climatogram, fig.asp=0.7, eval=TRUE}
# 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.:
```{r windrose, fig.asp=0.7, eval=TRUE}
# 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")
```
## ... and spatial!
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):
```{r spatial}
# 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")
)
```
