The type of weather station used determines which parameters are reported by that station and which need to be calculated by Cumulus. If Cumulus 1 is using temperature in a calculation of parameters like dew-point or apparent temperature, then for most stations it will apply any calibration settings to the temperature read from the station before using it in that calculation. Similarly if humidity is read from the station, the calibrated value is used in subsequent calculations. See the support forum for further information e.g. for Instromet stations, Cumulus 1 calculates the relative humidity from the reported wet bulb, and dry bulb, temperatures, the uncalibrated values of temperature and (calculated) humidity are then used to calculate dew-point. | The type of weather station used determines which parameters are reported by that station and which need to be calculated by Cumulus.
