On 2018-02-22 the tracker experienced problems and has stopped working since then. Therefore no DIF nor DIR data is available. Also note, that the Pyrgeometer has not been shaded since then and that the SWD pyranometer is not ventilated. To have at least some DIF data, a shadowband was reinstalled for the diffuse sensor on 4th of April 2022. The DIF data is to be taken with care.--Caution! It was found that from 23rd of July 2025 on the SWD data seem to be much too low. We are investigating this, until then please refrain from using the data.
