The main research hypothesis of this project is that spaceborne formaldehyde (HCHO), solar-induced fluorescence (SIF) and soil moisture can be used to improve the estimation of biogenic emissions of isoprene. We aim:
- to explain the variability and trends of biogenic VOC emissions in terms of climate and land use change, with a special focus on the effect of drought
- to design a better representation of the effect of drought on biogenic isoprene emissions based on satellite measurements of SIF yield, soil moisture, and calibrate/validate this parameterization against field data and spaceborne HCHO data, in particular during the summer 2018 European drought and the 2011/12 US drought
- to provide an improved version of the state-of-the-art biogenic emission model MEGAN, incorporating the response of isoprene emissions to drought using satellite SIF yield data.
ALBERI starts on September 1st, 2019 for a duration of 2 years.
