Data quality and uses.

This is an amateur-maintained weather station. At the moment, we strongly advise against using the data here in statistical analysis without prior cleaning and calibration using other sources. It would be easy to draw incorrect conclusions otherwise, because:

  • Observations are not gathered in similar conditions to ones used by the Met Office.
  • Our sensors are not calibrated against references.
  • Some sensors have been changed over time with ones working on different principles (see implementation).
  • Data contains inaccuracies, and the documented list is not exhaustive.

Most of those issues can be corrected for, by pre-processing the raw data. However, we have not yet released any quality-controlled dataset.
