get_precip_data: Get precipitation data

Description

This function takes information of where and when a set of environmental samples were collected and retrieves precipitation data (in millimeters) for those locations and times. Data come from the Open-Meteo Historical Weather API (https://open-meteo.com/en/docs/historical-weather-api) via the openmeteo R package. Additionally, the optional intervals argument specifies a set of intervals over which the function will calculate the cumulative sum of precipitation in millimeters (mm) for the previous X number of days for each location.

Usage

get_precip_data(lon, lat, dates, intervals = NULL)

Value

data.frame

Arguments

lon

A numeric vector giving the longitude of the sampling sites in Decimal Degrees.

lat

A numeric vector giving the latitude of the sampling sites in Decimal Degrees.

dates

A character or date vector of dates giving the date when each sample was collected (format is YYYY-MM-DD)

intervals

An integer vector giving a set of time intervals over which to sum the precipitation data. Default is NULL where the interval is 0 (returns the precipitation value at time t). If intervals=3 then the cumulative precipitation over the preceding 3 days is returned.

Examples

# \donttest{

tmp <- get_precip_data(lon = c(-56.0281, -54.9857),
                       lat = c(-2.9094, -2.8756),
                       dates = c("2017-12-01", "2017-12-31"),
                       intervals = c(1,3,7))

head(tmp)
