  1. Meteosat Flow Forecasting andDrought Monitoring Mark de Weerd, MSc. EARS Earth Environment Monitoring BV Delft, The Netherlands

  2. EARS Earth Environment Monitoring BV • Remote sensing company since 1977 • Delft, the Netherlands • Energy & Water Balance Monitoring • Climate, Water and Food applications: • River flow forecasting • Drought monitoring • Crop yield forecasting • Crop insurance

  3. MTSat FY2c METEOSAT IOC Meteosat MSG

  4. Precipitation Evaporation Heat Radiation Flow Energy en Water Balance

  5. Meteosat FengYun-2 WMO stations Hydrological model River flow forecasting Precipitation Rainfall processing Clouds Drought monitoring Drought processing Evaporation VIS & TIR Energy balance processing Temperature Albedo Crop growth model Crop yield forecasting Radiation Energy and Water Balance Monitoring System (EWBMS)

  6. Rainfall processing cold high medium high medium low • Meteosat TIR • Cloud top temperature • Cloud level • Cloud level durations (CDi) • GTS rain gauge data (R) • Regression: • R = a0+a1CD1+a2CD2+ …. • Calculate rainfall field 6

  9. Actual evapotranspiration product

  10. Time series (daily, 10-daily)

  11. Complete river basins

  12. Example project: Yellow River basin (2006-2009) Upper Yellow River Second largest river basin of China Wei River

  13. GMS / FY2precipitation data

  14. GMS / FY2 evapotranspiration data 1st quarter 2000 2nd quarter 2000 4th quarter 2000 3rd quarter 2000

  15. Water balance validation Upper Yellow River

  16. Land component: 2-dimensional diffusion process Surface & sub-surface flow Large Scale Hydrological Model (LSHM) Ql(t) Ql(t) Q(t) Hydrological Model by UNESCO IHE River flow component: Muskingum-Cunge routing EWBMS Precipitation & Evapotranspiration Q(t)

  17. Wei River flow simulation R2 = 0.75 Vol. error = 4% R2 = 0.80 Vol. error = 11%

  18. Wei River 24 hr forecast RMSE = 110 m3/s RRMSE = 0.37 COE = 0.75 R2 = 0.79

  19. High level interest at the2nd International Yellow River ForumZhengzhou, October 2005

  20. Yellow River project evaluation • By a Chinese high-level scientific commission • Classification: “World Leading Level” • 2nd Prize China Ministry of Water Resources

  21. Niger Basin project (2014-2017) • Niger Basin Authority (NBA), Niamey, Niger • Operational implementation • Drought monitoring • River flow forecasting

  22. Implementation project components • Meteosat receiver • PC network • Software • Pre-processing • EWBMS • LSHM • Utility GIS • Calibration & Validation • Training

  23. Meteosat antenna

  24. Receiving and processing office

  25. Training

  26. India Meteosat Indian Ocean Data Coverage (IODC)

  27. India

  28. Conclusions • Operational water monitoring and flow forecasting system • Distributed precipitation and evapotranspiration data Data: • Has at least a daily temporal resolution and a 5 km spatial resolution. • Is transboundary, uniform, objective and cost effective
