The Earth’s land surface, which comprises of rocks, soil , vegetation, water (as surface water bodies and stored in soil and rocks), snow, ice, and urban fabrics interacts with the overlying atmosphere in a number of complex ways. It is the land surface where we live, grow our crops, and let our cattle graze.
The land surface exchanges heat, momentum, water and carbon-dioxide with the atmosphere and hence plays a role in our microclimate, crop productivity, and can even affect extreme weather phenomena such as heat waves or floods. The land surface-atmosphere interactions can be summarised via the land surface energy-, water- and carbon balance, and related key processes, variables and parameters; it is these that are studied by members of the Land Surface Processes Cluster.

The purpose of the Land Surface Processes Cluster is to better exploit existing expertise, data and tools within the University of Reading and its collaborator Institutions to study land surface processes spanning a wide range of spatial and temporal scales, using both observations (in-situ and remote sensing) and modelling. For the latter, we help develop, test, and exploit both off-line Land Surface Models (LSMs), such as JULES and CTessel, and LSMs coupled to Numerical Weather Prediction (NWP) or Global Climate Models (GCMs). We also work with specialised models that facilitate research into the relationships between optical and thermal remote sensing and land surface processes (photosynthesis and energy balance fluxes), such as the SCOPEmodel, and with water balance-crop productivity models such as SWAP (Soil Water Atmosphere Plant).

Who 1: Academic staff and PDRAs
The cross-School interdisciplinary Land Surface Processes cluster combines research carried out at the University of Reading within the Department of Geography and Environmental Science, the Department of Meteorology, and NCAS-Climate together with external collaborators, in particular the Centre for Ecology and Hydrology (CEH), British Geological survey (BGS), the Met Office Hadley Centre and the European Centre for Medium range Weather Forecasts (ECMWF).

Impacts and Research
The cluster aims to generate impactful knowledge on the Critical Zone in the context of a range of research (predominantly NERC funded) and PhD projects, ranging from studies on climate extremes (flooding, droughts, heatwaves), to renewable energy (ground source heat pumps, biofuels). More widely, we participate in (inter)national research efforts on monitoring and modelling (e.g. CMIP) of the global water-, energy and carbon balance (WRCP, GEWEX).
