As part of our ongoing efforts to provide high-quality data with well-documented metadata, we are pleased to announce an update to the sensor information of the WEGENERNET network in Austria. This update includes details of previously used sensors, which may have been replaced by different or similar sensor types.

To ensure this information is accurately reflected in the data available on ISMN, we have reprocessed all WEGENERNET station data. As a result, some measurement time series have been segmented into smaller chunks based on the historical sensor change records. While this may lead to changes in the number and structure of time series components, the recorded measurement values remain unchanged.

Information about a sensor change or the reinstallation of a sensor is important for the user of the data. This is because the characteristics of the measurements, such as the mean value or the variance, can be altered by a change in compaction of the soil during reinstallation at the same location, by small-scale differences in soil properties when the exact measurement location is changed or by a change of the sensor type.
If you have previously downloaded data from WEGENERNET and consider this update relevant to your analysis, we recommend re-downloading the data https://ismn.earth/en/dataviewer/.

We sincerely thank Jürgen Fuchsberger for providing this valuable information and for his support during the implementation process.
