Meteorological factors play an important part in plant phenology. Long-term records from the Swiss Meterorological Institute (SMI, MeteoSwiss) indicate that climate is changing in Switzerland, particularly in the mountains. Warming appears to be much more important at this scale than on the global scale. These regional climate changes are likely to have an effect on forest ecosystems. However, to document these changes, and to understand the short-term dynamics in the ecosystems, site-specific meteorological data are required. In addition, detailed analyses of specific aspects of the evolution of climate in Switzerland are necessary.

Project aims

To collect continuous meteorological data from inside and outside the plots. To determine the climatic characteristics of each plot.

To identify changes in stand microclimate during the course of the project.

To compare microclimatic conditions inside and outside the research plots.

Establishment of a meteorological LTFER-database. Linking of LTFER-data with those of the Swiss Climate Database (SMI, MeteoSwiss) and analyses of specific aspects of the evolution of climate in Switzerland.

The following variables are collected: air temperature, air humidity, wind speed, wind direction, solar radiation, PAR, UV-B radiation, precipitation.
