	So the [[Hourly_radiation_(~~Heat_Overlay~~)\|global radiation for the hour]] has to be calculated as the average of the past hour and the next hour. We use the ''Q'' column from the [[KNMI weather data]] for this. Additionally, the global radiation is in J / cm<sup>2</sup> and has to be converted to W / m<sup>2</sup> by multiplying:		So the [[Hourly_radiation_(Heat Stress Overlay)\|global radiation for the hour]] has to be calculated as the average of the past hour and the next hour.
