| Zusammenfassung |
| Scintillometry is widely recognized as a potential tool for
obtaining spatially aggregated sensible heat fluxes at regional
scales. Although many investigations have been made over contrasting
component surfaces, few aggregation schemes consider footprint
contributions. In this paper, an approach is presented to infer
average sensible heat flux over a very heterogeneous landscape by
using a large aperture scintillometer. The methodology is
demonstrated on simulated data and tested on a time series of
measurements obtained during the SPARC2004 experiment in Barrax,
Spain. Results show that the two-dimensional footprint approach
yields more accurate results of aggregated sensible heat flux than
traditional methods. |
