Augmenting long-term ecosystem-atmosphere observations with multidisciplinary intensive campaigns aims at
closing gaps in spatial and temporal scales of observation for energy- and biogeochemical cycling,
and at stimulating collaborative research.

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

Contributions: SPIE Conference 2016, AGU Fall Meeting 2016, 97th AMS Annual Meeting and the EGU General Assembly 2017.

Other: Purdue University, Max Plank Institute BGC-Jena and local media.


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).

More than 65 researchers, from 20 groups in research and industry, teamed up for ScaleX.


Inquiries about ScaleX can be sent to the coordinator, currently Matthias Zeeman of KIT IMK-IFU.


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.
