posieux_weather: Example Weather Data

posieux_weatherR Documentation

Example Weather Data

Description

Datasets containing the weather input parameters as used by growR. The same data is made available as plain text files by the package and automatically found in the input directory created by setup_directory() if the include_examples option is set to TRUE (default).

Usage

posieux_weather

Format

A data.frame with 3652 rows and 10 variables:

year

Year as an integer

DOY

Day of year as an integer

Ta

Average temperature of the day in degree Celsius

Tmin

Minimum temperature of the day in degree Celsius

Tmax

Maximum temperature of the day in degree Celsius

precip

Daily precipitation in mm

rSSD

Relative sunshine duration in percent

SRad

Sun irradiance in J / s / m^2. This can be converted into photosynthetically active radiation (PAR) in MJ / m^2 as: PAR = SRad * 0.47 * 24 * 60 * 60 / 1e6

ET0

Evapotranspiration in mm.

snow

Precipitation in the form of snow in mm

Details

For use in growR, a WeatherData object has to be created from a plain text file. Therefore, this dataset is only provided for convenient inspection. In order to run growR, use the plain text files provided by the package. Use system.file("extdata", package = "growR") to locate them.

The snow column is not actually used by growR but rather calculated through precipitation and temperatures in WeatherData⁠$read_weather()⁠.

Likewise, the rSSD column is deprecated, currently unused and only kept for backwards compatibility.
