How high & wide rivers run

SWOT L2 HR River Single Pass
PO.DAAC SWOT_L2_HR_RiverSP cloud-native vector reaches (typically 10-km river segments) 21-day repeat shapefileNetCDF hydrologyrivers

Globally rivers ≥100 m wide — height + width + slope per reach. Pre-SWOT this required ground gauges (sparse outside US/Europe).

Access

Gotchas

  • Use Hydrocron REST API for time-series at reaches (much easier than raw L2)
  • 20-km nadir gap means some reaches are missed per pass
  • Validation papers (2025) show 5-10 cm bias vs gauges for narrow rivers
  • Other datasets: d044, d032
