ASCAT Soil Moisture (H SAF)
Near-real-time scatterometer soil moisture from EUMETSAT — hours of latency, useful for operational monitoring.
R client for the UK National River Flow Archive — catalogue, gauged daily flows and catchment metadata.
Install
install.packages("rnrfa")rnrfa wraps the UK National River Flow Archive's API in R: search the station catalogue by location or river, retrieve gauged daily flows and catchment properties, and get everything back as tidy objects ready for FEH-adjacent statistics and trend work.
UK flood hydrology leans heavily on NRFA records, and rnrfa makes their retrieval scriptable and reproducible — the difference between a one-off spreadsheet and an auditable analysis when the review letter arrives.
