Fig. 5From: Differential responses of carbon and water vapor fluxes to climate among evergreen needleleaf forests in the USAA comparison of the normalized wavelet spectra of net ecosystem CO2 exchange (NEE, μmol m−2 s−1) and evapotranspiration (ET, mm 30-min−1) at each forest site. Half-hourly data were used in the analysisBack to article page
