Useful for

Use cases llm-inferred: Long-run temperature and rainfall context for an England and Wales climate baseline section · Historical rainfall and outflow context for a water resources or abstraction narrative · Sense-checking long-term national rainfall trends against local design rainfall inputs
Audience llm-inferred: hydrologists · flood consultants · water resources engineers · climate and environmental consultants · planners

Limitations

Constraints docs-verified: Discontinued and superseded by CEH National River Flow Archive and EA water situation reports · Temperature and rainfall series ends in 2012; outflow and rainfall CSVs end in 2013 · England and Wales only for the temperature and rainfall series · Country-level aggregates, not catchment or gauge-level data · Last updated 12 December 2017, so not suitable for current conditions
