Dr Jennifer Brooke
Jenn works on representing land surface and boundary layer processes in the Met Office Unified Model with a particular interest in semi-arid regions.
Areas of expertise
- Land surface modelling.
- Land surface - atmopshere coupling.
- Land surface temperature.
Jenn is a Senior Scientist in the Land Surface and Atmospheric Boundary Layer group working to improve the representation of land surface and boundary layer processes in the Unified Model.
Jenn is co-coordinating the organization of an international field campaign, LIAISE (Land surface Interactions with the Atmosphere over the Iberian Semi-arid Environment). The project will bring together ground-based and airborne measurements with modelling studies to lead to an improved understanding of processes such as soil moisture, evapotranspiration, precipitation through atmospheric coupling and the subsequent feedbacks to the Mediterranean boundary layer.
Land surface-atmosphere interactions play a critical role in the development of the atmopsheric boundary layer and help to determine the near surface temperature and humidity throughout the diurnal cycle. Studies have shown that these interactions are strongest in semi-arid regions where there is both a sensitivity of the surface fluxes to the soil moisture profile, and a sensitivity in the atmosphere to these surface fluxes. Semi-arid regions pose a significant modelling challenge due to the highly heterogeneous nature of the environment.
The other focus of research is developing the Met Office LEM to more fully represent the feedback between the evolving land surface and the atmospheric boundary layer.
Jenn joined the Met Office in November 2013 where she spent 5 years in the Radiation Research Group in Observation Based Research. During this time, Jenn was researching model biases in land surface temperature and the surface energy balance in the Unified Model and the JULES land surface model. This work used ground-based observations obtained during the SALSTICE campaign (2013) and the INCOMPASS project (2016). Jenn has additionally participated in a number of international observational campaigns including Fennec (2011), SAMBBA (2012), ICE-D (2015), and COSMICS (2015).
Prior to joining the Met Office, Jenn completed her PhD at the School of Earth and Environment, University of Leeds. The PhD was co-sponsored by the Met Office through a CASE award. Her PhD contributed to an improved understanding of the physical and optical properties of biomass burning aerosol across the Amazon region. Jenn received a MChem degree in Chemistry with a Year in Industry from the University of York, Department of Chemistry in 2009, with a year spent working at DSM in The Netherlands.
