Table I. Monthly mean values of temperature (T), relative humidity (RH), precipitation  (P), short wave solar radiation (Rs), photosynthetically active radiation (PAR), and net  radiation (R net ) in Mogostos (1999-2006).
Fig. 2. Indicative CO 2  hourly fluxes during (a) seven days of the leafless stage  and (b) seven days of the fully leafed stage (1999).
Fig. 3. Daily means of (a) CO 2  flux data and CO 2  flux estimates (dashed line),  (b) R net  and absorbed PAR flux densities, (c) air temperature at 25 m height, (d)  soil moisture at 10, 60 and 120 cm depths, and (e) LAI evolution.
Figure 8 shows the net productivity data (in terms  of NEE values) as a function of site latitude for forests  in various world climates provided by several authors  (Valentini et al., 2000; Griffiths and Jarvis, 2005;  Hyvönen et al., 2007; Etzold et al.,
