Data quality is extremely important, Therefore, before they are incorporated into the database, all data are screened to detect incorrectly formatted data and values outside the expected range. The data providers (i.e. the site staff) may also submit metadata in the form of quality codes, which are stored alongside the data. Such metadata can be very useful when the data are subsequently analysed. From time-to-time we carry out quality assurance exercises on specific datasets, e.g. to test the accuracy of vegetation identification, or to check the calibration of automatic meteorological sensors.
