- NASA Earthdata & ECMWF Copernicus Climate Change Service (C3S)
- Reference
- RUN-20260915-051
- Aim
- Catalog high-temporal-resolution gridded precipitation fields and thermal/freezing-level reanalysis context for the high-altitude ungauged source catchments.
- Source and interface
- NASA Earthdata & ECMWF Copernicus Climate Change Service (C3S) — NASA CMR and ECMWF Copernicus Climate Data Store (CDS)
- Search method
- Query NASA CMR for GPM IMERG Final Precipitation V07 (half-hourly and daily) for August 2026 over central Nepal; query CDS for ERA5-Land hourly surface temperature and 0°C isotherm level across the Langtang–Gyirong catchment (June–August 2026).
- Criteria
Spatial extent WGS84 [84.3976, 27.7320, 85.5508, 28.3500] Temporal window 2026-06-01 through 2026-08-31. - Coverage
- Atmospheric forcing and precipitation grids spanning the pre-event monsoon accumulation and the 26 August 2026 event window.
- Stopping rule
- Exhaust official CMR collections and CDS product endpoints for the target window and bounding box.
- Result
2 authoritative meteorological resources recovered across 4 assets: NASA GPM IMERG V07 precipitation grids and ECMWF ERA5-Land temperature/freezing level series.
