WFD Cycle 1 2014 Improvements (England)

This dataset contains Cycle 1 Water Framework Directive (WFD) class improvements at water body level, for England only, for the year 2014, for quality elements. This dataset also contains the statistical confidence and derived certainty that a real improvement in class has occurred. Improvements are assessed by detecting upgrades in class status in 2014 against the baseline status of 2009, and estimating the confidence that a real improvement in class has occurred.
