hydroscoper is an R interface to the Greek National Data Bank forHydrological and Meteorological Information,Hydroscope. For moredetails checkout the package’swebsite and the vignettes:

• An introduction tohydroscoperwith details about the Hydroscope project and the package.
• Usinghydroscoper’s datasetswith a simple example of how to use the package’s internal data sets.

Install the stable release from CRAN with:

install.packages("hydroscoper")

You can install the development version from GitHub with:

# install.packages("devtools")devtools::install_github("ropensci/hydroscoper")

The functions that are provided byhydroscoper are:

• get_stations, get_timeseries, ..., etc. family functions, toretrieve tibbles with Hydroscope’s data for a given data source.
• get_data, to retrieve a tibble with time series’ values.
• hydro_coords, to convert Hydroscope’s points’ raw format to atibble.
• hydro_translate to translate various terms and names from Greek toEnglish.

The data sets that are provided byhydroscoper are:

• stations a tibble with stations’ data from Hydroscope.
• timeseries a tibble with time series’ data from Hydroscope.
• greece_borders a tibble with the borders of Greece.

This is a minimal example which shows how to get the station’s200200precipitation time series56 from thekyy sub-domain.

Load libraries and get data:

library(hydroscoper)library(tibble)library(ggplot2)ts_raw<- get_data(subdomain="kyy",time_id=56)ts_raw

Let’s create a plot:

ggplot(data=ts_raw, aes(x=date,y=value))+  geom_line()+  labs(title="30 min precipitation for station 200200",x="Date",y="Rain height (mm)")+  theme_classic()
