Understanding land-atmosphere exchange processes in land-use transformation systems (A03)

• Subject Area: Human Geography
• Term: from 2012 to 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 192626868

In this project, we aim to improve our understanding of land-atmosphere exchange processes in land-use transformation systems at multiple scale. In WP1, we measure continuously soil respiration using automatic chambers to improve nocturnal CO2 flux estimates. In WP2, we measure sun-induced fluorescence (SIF) as well as campaign-based leaf gas exchange on different oil palm leaves to characterise photosynthesis. In WP3, we quantify key microclimatic variables in the areas covered by the Landscape Assessment using mobile mini meteorological stations. In WP4, we want to synthesize flux data from various land-use systems in South East Asia.
