A data set containing weather data measured in Viikki, Helsinki, Finland. Values for all variables are means of 12 readings at 5 seconds intervals. Sun angles were computed with R package 'photobiology'.
weather_wk_25_2019.tbA tibble with 21 columns and 10080 rows.
The variables are as follows:
time (yyyy-mm-dd hh:mm:ss)
PAR_umol (umol m-2 s-1)
PAR_diff_fr (/1)
global_watt (W m-2)
day_of_year
month_of_year
month_name
calendar_year
solar_time (h)
sun_elevation (degrees above horizon)
sun_azimuth (degrees)
was_sunny (T/F)
wind_speed (m s-1)
wind_direction (degrees)
air_temperature_C (C)
air_RH (
air_DP (C)
air_pressure
red_umol (umol m-2 s-1)
far_red_umol (umol m-2 s-1)
red_far_red (ratio)
