Carbon and oxygen isotope ratios in wood constituents of Pinus halepensis as indicators of precipitation, temperature and vapour pressure deficit
Carbon and oxygen isotope compositions (δ13C, δ18O) in tree rings have been shown to bear relevant climatic signals. However, little is known about the interrelationship between both isotopes in wood… Expand
SPALINET : THE S PANISH LIDAR NETWORK . R ESULTS FROM THE FIRST YEAR : SYSTEM INTERCOMPARISON
To extend and reinforce the action of the EARLINETASOS project, a network of Spanish advanced lidars was created. Six systems were intercompared satisfactorily in terms of signal similarity and… Expand
NEW STRATEGIES FOR THE APPROACH TO THE SOCIETY DEMANDS OF THE FINAL DEGREE PROJECTS IN THE UNIVERSITY DEGREE IN CHEMISTRY
Interactive comment on “ Unexplained hydrogen isotope offsets complicate the identification and quantification of tree water sources in a riparian forest ” by Adrià Barbeta et al .
- J. P. Díaz
The work by Barbeta et al. highlights one critical issue in the application of stable isotopes as hydrological tracers for the study of plant water uptake patterns. Methods are described properly,… Expand

In the modeling of aerosols effects in the energy budget, radiative forcing, two parameters are mainly used: the asymmetry parameter, g and the back scattering parameter, R. These parameters have been evaluated with the aerosols distributions obtained by King's inversion method. Expand
Uncoupling between soil and xylem water isotopic composition: how to discriminate mobile and tightly-bound water?
As a general rule, no isotopic fractionation occurs during water uptake and water transport, thus, xylem water reflects source water. However, this correspondence does not always happen. Isotopic… Expand
