Project Summary This project will advance the state of the art in Earth Observation (EO) data assimilation in two specific areas – land surface processes and atmospheric composition. Interfacing Earth Observation Data with Atmosphere and Land Models

Project Overview Creating a comprehensive characterisation scheme for vegetation type is a longstanding problem in Earth system modelling. The myriad soil and vegetation types with their seasonal changes mean that quantifying the nature of the land surface at any particular point is hugely taxing. And taking sufficient detailed observations to verify any global scheme is an enormous undertaking.

Project Overview continued This project will build on the growing research in this area, first by advancing the latest vegetation and radiative transfer models and then by incorporating these into an updated version of the new Earth Observation Land Data Assimilation System (EOLDAS) model. This will provide a cutting-edge surface data assimilation system for continuing research.

Project Overview continued The second area of research is in quantifying greenhouse gas emissions. Attempts to model such emissions suffer from similar difficulties as for vegetation modelling: changes in emissions are localised, vary with season, and are difficult to observe in sufficient detail so that the models can be verified. On top of this, the emissions of anthropogenic sources are hard to distinguish from the emissions of natural sources.

Project Overview continued The question of sufficient observations will be tackled first, as Observing System Simulation Tools will be developed, documented and made available to the wider community. Improvements to model performance will then be made to allow higher resolution runs, and two data assimilation techniques for distinguishing between natural and anthropogenic greenhouse gas emissions will be compared
