Short summary
A novel approach that uses tipping point analysis for identifying instrumental changes in sensor data that may not have full description of legacy hardware. The technique helps interpret changes of pattern in the data (autocorrelations) and distinguish them from climatic and environmental effects. This is particularly important for historic datasets, where instrumental changes may be undocumented or lack metadata.
