Profile
Summary: 

Estibaliz has been working as a scientist in ECMWF since 2016.

She has participated in different European projects including ANYWHERE, IMPREX, MISTRAL and HIGHLANDER mainly producing new products for high-impact weather and investigating ECMWF IFS and ERA5 post-processing and statistical downscaling methods of ensemble forecast (especially precipitation).

She also works as an analyst in the 'Forecast Daily Report' group whose main task is the analysis and diagnostic of model performance issues in ECMWF forecast.

She is currently involved in the new Destination Earth initiative evaluating extreme events at km-scale global forecasts through the Extremes Digital Twin framework. 

Professional interests: 
  • Post-processing and statistical downscaling of forecast outputs.
  • New products for high-impact weather forecast.
  • Real-time assessment of forecast model performance.
  • Predictability at all lead times.
  • Extreme events and km-scale global forecast. 
  • Training forecast users via webinars or training courses.
