3. Motivation and main goals
Build up a complex experimental setup for investigation of surface layer and Boundary layer processes (profiles, fluxes)
Concentrate micrometeorological instrumentation from Hungary based on the infrastructure of Aerological Observatory Szeged.
– Investigate surface energy budget components and the energy budget closure – comparison of radiation sensors – comparison of flux calculation methodology – eddy covariance – gradient technique (similarity theory)
– Local inhomogenity (surface temperature, soil moisture, etc.)
– Development of stable PBL
– Comparison of PBL profile measurement techniques
(balloon, Radiosonde, SODAR WindProfiler, UAV, Quadrocopter)
– Model comparison (1D PBL, WRF)
