Get temperature data — get_temp

This function takes information of where and when a set of environmental samples were collected and retrieves temperature data (measured in accumulated degree-days) 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. The optional intervals argument specifies a set of intervals over which the function will calculate the accumulated temperature in the form of Accumulated Thermal Units (ATUs) for each interval.

Usage

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

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 to calculate accumulated degree-days. Default is NULL where the interval is 0 (returns the daily temperature in degrees Celsius at time t). If intervals=3 then the accumulated degree-days for the preceding 3 days is returned.

Value

data.frame

Examples

if (FALSE) {

tmp <- get_temp_data(lon = c(30.0281, -52.9857),
                     lat = c(15.9094, -25.8756),
                     dates = c("2020-08-01", "2020-12-31"),
                     intervals = c(1,5,10))

head(tmp)
