The BAQ 0.5km Forecast system is updated every 3h and runs on the Granado HPC cluster at Universidad del Norte.

Fetches data from NOAA (GFS) and OGIMET (METAR). Surface level observations are interpolated into the GRIB files.

  • Forecast: +2-4h.
  • Grid points distance: 0.5km.
  • GFS: 0.25 degree resolution, global longitude-latitude grid.
  • GFS cycle: 00 UTC.
  • Altitude: 150m.
  • Isobaric level: 1000hPa.
  • Interactive map grid size: 26x15.
  • Interactive map points distance: 2km.
