Profile
Summary: 

Melanie joined ECMWF in September 2016 to work on the assimilation of satellite observations of aerosols and other atmospheric composition species in the Copernicus Atmosphere Monitoring Service (CAMS) global assimilation and forecasting system. She is part of the team which monitors and improves the impact of current satellite instruments and evaluates the use of new instruments, such as those from the European Sentinel missions.

Professional interests: 
  • Operational services for atmospheric composition
  • Air quality forecasting
  • Data assimilation of atmospheric composition
  • Remote sensing and retrieval methods
  • Variational and ensemble assimilation methods

 

Career background: 

Melanie Ades completed her PhD in July 2013 on Data Assimilation in highly nonlinear systems with Prof. Peter Jan van Leeuwen at the University of Reading. In her thesis she studied a particle filter method for nonlinear data assimilation with application to meteorological models. She then continued to work at Reading University on nonlinear assimilation methods such as Markov Chain Monte-Carlo methods before becoming a National Centre of Earth Observation (NCEO) Research Fellow in Data Assimilation methodology. Since 2016 she has been working on the assimilation of satellite observations of atmospheric composition species at ECMWF.
