Hey everyone, good discussion. I’d like to answer a few questions on calibrations
We can apply a calibration adjustment manually to the solar irradiance readings. Usually, a simple offset will suffice. If you have reference data to share, great, clear days with single peaks are helpful. Submit a help ticket and we’ll take care of you!
On the ambient temperature correction…
The Tempest software adjusts the raw temperature reading to an ambient temperature simulating a fan aspirated environment. This correction is calculated using solar radiation and wind speed data. Stronger irradiance values and light or calm winds will yield a higher temperature correction up to a maximum of 1.5 degrees F.
Temperature discrepancies are often explained by location differences. Siting of weather equipment can also play a role, heat sources, or radiant heat from a roof or the side of a house can contribute to discrepancies.
