ASCAT Soil Moisture (H SAF)
Near-real-time scatterometer soil moisture from EUMETSAT — hours of latency, useful for operational monitoring.
Canadian government R package for streamflow analysis — trends, frequencies and summaries from HYDAT.

install.packages("fasstr")fasstr (Flow Analysis Summary Statistics Tool for R), from the Province of British Columbia, analyses daily streamflow with an emphasis on the statistics Canadian practice reports: long-term summaries, annual and seasonal statistics, trend analysis (via zyp/Mann-Kendall), volume-frequency and low-flow frequency analyses — pulling records straight from Environment and Climate Change Canada's HYDAT database via tidyhydat.
For Canadian hydrology it is the shortest path from gauge to defensible statistics; elsewhere it still offers one of the tidiest streamflow-statistics APIs in R.
