O 3.1 in Horizontal and vertical trace gas advection
06.10.2009, 14:40-15:05, Kutschenhaus
Advection measurements at the Waldstein/Weidenbrunnen FLUXNET site were conducted during three experiments: Waldatem 2003, EGER IOP1 2007 and EGER IOP2 2008. Techniques applied to measure horizontal gradients of CO2 are presented ranging from the well known single analyzer approach using a switching valve system (applied in 2003 and 2007) to a multi-instrument setup (applied in 2008). Advection estimates from the different setups are presented as well as an overview over the statistical approach developed to make use of the multi-analyzer measurements. Finally, the effect of advection on estimates of NEE will be shown.
