BB--who even intimated that you were overstating the case? Those dastardly conifers!  P.S. State parks has officially approved the environmental piece on the well at the ski hill. John

Estimating forest rainfall interception
from satellite observations
Although most rainfall over continents
reaches the ground, a significant portion is
caught by the forest canopy and evaporates
directly. To better understand feedbacks
between evaporation and climate and to
estimate the effects of climate change and
deforestation on water resources, scientists
need to know how much rainfall is
intercepted by the canopy. Miralles et al.
applied satellite rainfall data to an existing
model to create global maps of estimated
forest rainfall interception. They found
that interception loss accounts for 13% of
rainfall over broadleaf evergreen forests,
19% in broadleaf deciduous forests, and
22% in needle-leaf forests. The researchers
compared their model estimates with
field observations and found they were
in good agreement. (Journal of Geophysical
