Regional evaporation at grid / pixel scale over heterogeneous land surfaces (EVA-GRIPS) - numerical investigation of turbulent structures over heterogeneous land surfaces with a parallelized LES model (EVA-NITS)
Responsible: Jörg Uhlenbrock
Project type: ​BMBF project (the sub-project EVA-NITS belongs to the joint project EVA_GRIPS which is part of the framework programme DEKLIM)
Duration: 01/01/2002 - 31/12/2004

The main goal of the joint proposal EVA-GRIPS is the determination of area-averaged evaporation on the scale of a gridbox of a regional climate model or of pixels of sattelite images over heterogeneous land surfaces. This goal should be achieved through a combination of measurements, numerical modeling and interpretation of satellite data. The special goal in this subproject is the simulation of the atmospheric boundary layer over the Lindenberg area with a very high resolution. The LES-model shall provide independent sets of tubulence data, which will be compared with the measurements of turbulence gathered by experimental groups and which will complete these measurements. Furthermore, these data sets will be used to validate the turbulence-parameterizations of mesocale models.
