Description

This data set contains level1 solar and infra-red radiation and soil heat flux variables of the eddy-covariance station in Birkholz (Rietz-Neuendorf) during FESSTVaL 2021 from May to August. All values are retrieved by averaging the single samples of each minute. The sampling frequency of the instrument is 1 second. Further values like albedo and radiation balance are calculated from the measured values.

Limitations: The data was processed by approved software including basic plausibility checks. Gaps in the data set can be caused by maintenance work, power loss, mal-function, or similar reasons. Single missing values are filled by interpolation. A description of the used formulas and plausibility checks exists and can be retrieved from the contact person.
