Champaign, IL weather data specified at hourly intervals in the CST time zone for the years 1995--2023. The data includes typical inputs required for BioCro imulations. Note: some values are missing near the start of 1995 since those time points are not available from SURFRAD.
This weather data is included in the BioCro package so users can reproduce the calculations of Lochocki et al. (2022) [tools:::Rd_expr_doi("10.1093/insilicoplants/diac003")] and for exploratory purposes; it is likely that most BioCro studies will require different data sets, and no attempt is made here to be exhaustive.
weatherA list of 29 named elements, where each element is a data frame corresponding
to one year of weather data and the name of each element is a year, for
example '2004'. Each data frame has 8760 or 8784 observations
(representing hourly time points) of 9 variables:
year: the year
doy: the day of year
hour: the hour
time_zone_offset: the time zone offset relative to UTC (hr)
precip: preciptation rate (mm / hr)
rh: the ambient relative humidity (dimensionless)
solar: the incoming photosynthetically active photon flux
density (PPFD) measured on a ground area basis including direct and
diffuse sunlight light just outside the crop canopy
(micromol / m^2 / s)
temp: the ambient air temperature (degrees Celsius)
windspeed: the wind speed in the ambient air just outside the
canopy (m / s)
