Abstract in another language
Two models for predicting near-surface flux and concentration footprints are compared concerning their performance in the presence of heterogeneous surface conditions. One of the models is a conventional Lagrangian backward model and the second an LES model with an embedded Lagrangian footprint model. The latter model reveals generation of thermally induced secondary circulation under such surface heterogeneity. The conventional Lagrangian backward model with simple parameterization of flow conditions mostly performs well in footprint predictions for concentrations and somewhat worse for fluxes, and fails only in areas where flow patterns are dominated by pronounced secondary circulations.
Abstract in another language
Zwei Modelle zur Bestimmung der bodennahen Fluss- und Konzentrationsfootprints werden hinsichtlich ihrer Leistungsfähigkeit für heterogene Unterlagenbedingungen verglichen. Das erste Modell war ein konventionelles Lagrangesches Rückwärtsmodell und das zweite ein LES Modell mit eingebetteter Lagrangescher Footprintmodellierung. Letzteres zeigt die Entstehung von thermisch induzierten Sekundärzirkulationen unter heterogenen Bedingungen. Das konventionelle Lagrangesche Rückwärtsmodell erfüllte weitgehend die Footprintbestimmung selbst mit einer einfachen Parametrisierung der Strömungsbedingungen. Es versagt lediglich in den Gebieten, die von den Sekundärzirkulationen dominiert wurden.
