Next The structure of the next ScaleX Campaign — to take place in 2019 — was first discussed during the TERENO Int'l Conference, Berlin, Oct 2018.

¶ Workshops: The most recent ScaleX Workshop took place on 29—30 Mar 2017 at KIT IMK/IFU, Garmisch-Partenkirchen. A ScaleX Workshop on UAVs took place on 8—9 Dec 2016, at U Augsburg/ISSE.

Campaigns

A scale expansion is achieved by linking observations of surface fluxes and surface properties to remotely sensed and airborne observations of atmospheric properties, as well as to process models up to the meso-scale. Topics were identified for each campaign and organised as voluntary Work Packages (WPs).

WP1: The impact of complex terrain on biosphere—atmosphere exchange processes
WP2: The nocturnal boundary layer: vertical transport, trace gas distribution and budget
WP3: Patterns of precipitation and soil moisture from site to regional scale
WP4: Regional water and energy budgets and balances analysis by modeling and observation in the catchments of Rott and Ammer
WP5: Distributed modeling of biosphere—atmosphere GHG exchange

The campaign at TERENO observatory Fendt involved collaborators and (inter-)national partners from academia and industry.

About

The ScaleX campaigns in the TERENO—preAlpine observatory were designed to address an overarching research question:

How well can our observations constrain modeling uncertainties of biogeochemical cycles,
and close the balances of energy and matter flows?

The TERENO (TERrestrial ENvironmental Observatories) network is a large-scale integrative observation program designed to determine the long-term ecological and climatic impact of global environmental change at regional scales.

The TERENO—preAlpine observatory in mountainous terrain of Bavaria, Germany, includes three core grassland sites at different elevations (600, 750 and 860 m a.s.l), at which surface exchange fluxes are observed by eddy-covariance, lysimeters and chamber system clusters. The site arrangement represents a climatic gradient. Specific to the Fendt site is the addition of a hydro-meteorological observation network.

ScaleX was initiated by KIT IMK-IFU under direction of HaPe Schmid. Benjamin Wolf coordinated ScaleX until Feb 2016.
