BVOCs are a key source of ozone and secondary aerosol precursors, and emissions are sensitive to both climate and CO2, but strongly dependent on plant type.
The aim of the project is to utilise multiple data sources to improve the representations of BVOC emissions from plants. This project will analyse species-level variation and use remotely-sensed data to improve modelling of BVOC emissions.
The main goals are to:
- develop a new synthesis of available plant-level information and understanding about sources of the most important BVOCs and their environmental dependencies;
- incorporate this information into a new generation of global BVOC emission model to be coupled into the Land Processes and eXchanges (LPX) modelling framework;
- perform and analyse model runs forced by historical to contemporary climates and CO concentration;
- use the available remotely sensed information on HCHO, and potentially other species, in combination with LPX-modelled pyrogenic emissions and independent information on industrial sources of volatile organic compounds, to evaluate the modelled fields for the years in which the satellite data are available;
- apply the information obtained in the model-data comparison to optimize the emissions model;
- analyse the research findings in terms of their implications for Earth system feedbacks.
