ABSTRACT

Precipitation and net radiation are fundamental parameters controlling plant transpiration, a key process in vegetation development. Either of these two meteorological parameters can be a limiting factor for vegetation growth. In humid areas such as northwest Europe, precipitation is abundant or even excessive, and the primary limiting factor for vegetation development in these “energy-limited” environments is
