Cloud/foggy forest could be studied from the surface heat and moisture fluxes, CO2 flux, decline, scattering of solar radiation, evapo-transpiration rate and photosynthesis. The chemical characteristics of cloud/fog water intercepted by forest trees also provide much information on forest ecosystem. This project tries to combine the researching resources from the college of sciences and experimental forest in Nation Taiwan University (NTU), and have intensive interaction with the climatology working group of Munster University (CWG-MU) in Germany. A short-term field campaign (during summer-autumn of 2013) will be held at Xitou forest recreation site (~1000m elevation) in western Taiwan. A 40-m flux tower and an agriculture weather station are the bases for field observation on cloud/fog phenomenon. All cloud/fog physical measuring facilities from NTU and chemical measuring facilities from CWG-MU will operate at same time period for advanced research on cloud forest related issues, such as the time–depth-density of cloud/fog, possible sources of water composition and its impact to forest ecosystem. The supporting from DAAD/NSC could create the face-to-face interaction on sites in Taiwan and Germany.雲霧森林通量觀測塔溪頭營林區cloud/foggy forestflux towerXitou forest recreation site
