Jasper Denissen

Scientist (High Resolution Earth-System Modelling)
Research Department, Earth System Modelling Section, Coupled Processes Group


Jasper joined ECMWF in 2022 as part of the Destination Earth Project. His background is in land-atmosphere interactions and his work at the ECMWF focusses on improving land initial conditions for high-resolution weather simulations and developing land-atmosphere coupling-strength diagnostics.


Professional interests:
  • Land surface modelling
  • Developing diagnostics for validation and statistical analysis of high-resolution model output
  • Land-atmosphere interactions, water vs. energy limitation, terrestrial evaporation, soil moisture.
