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.
