Published discharge

Read the per-segment and per-watershed discharge wet publishes.

Daily and monthly flow at hydrometric stations, and the gauges the water balance is fitted at.

wet_station_daily(): Daily flow at hydrometric stations, from HYDAT through to the present
wet_station_monthly(): Observed monthly and annual flow climatology at HYDAT stations
wet_station_doy(): Observed day-of-year flow climatology at HYDAT stations
wet_station_select(): Natural-flow HYDAT stations with a usable record in a period
wet_station_snap(): Snap HYDAT stations to FWA fundamental watersheds, checked by drainage area

Daily water temperature at stations, gap filling and growing season degree days.

wet_temp_daily(): Daily water temperature at hydrometric stations
wet_temp_fill(): Daily water temperature with gaps filled from air temperature
wet_temp_gsdd(): Growing season degree days per station-year

Define month-day windows, and take mean flow or per-year statistics of flow or temperature over them.

wet_flow_window(): Mean flow over date windows, from monthly or daily means
wet_window_stats(): Statistics of a daily series over date windows, one value per year
wet_windows_calendar(): Calendar months and seasons as date windows

Fetch PCIC VIC-GL gridded variables and summarise them per year.

wet_pcic_url(): OPeNDAP URL for one PCIC VIC-GL gridded variable
wet_pcic_index(): OPeNDAP index ranges for a bounding box and date range on the PCIC grid
wet_pcic_fetch(): Download a PCIC VIC-GL subset over OPeNDAP
wet_pcic_annual(): Mean annual total per cell, fetched one year at a time
wet_runoff_annual(): Mean annual total per cell from a daily raster
