Measurements of crop radiation balance, soil temperatures, heat fluxes and moisture, sensible and latent heat fluxes, meteorological conditions and plant growth were made for a mature vine stand in central Spain. Data were collected for a continuous mainly hot and sunny 50 day period from first shoot appearance to extensive canopy cover, during the summer of 1991, as part of an extensive desertification study in the area. Results are presented to illustrate both the diurnal and longer term variations of the components, and comparisons are made with similar measurements for a nearby arable site.
