8 % scattered by atmosphere
6% reflected by earth’s surface = f (sfc albedo)
Solar energy drives the world’s climate…Of the radiation received at the surface of the atmosphere:
19% absorbed by greenhouse gases (as well as longwave radiation from surface)
Leaves 46% absorbed by the earth’s surface which goes to heating the surface or evaporation.
17% reflected by clouds = f(cloud albedo)
= processes altered by human activities
Soil Temperature Dynamics: Forcing
Soil Temperature Profiles
Diurnal vertical heat transmission from solar inputs Follow downward heat pulses
Heat transmission from fire event
Seasonal vertical heat transmission note dampening and lag of signal
Seasonal vertical heat transmission note convergence on annual mean T at depth compare x- & y- axis scales with diurnal profiles
Borehole Temperatures
Annual to centennial vertical heat transmission
T record reconstruction
from signal unmixing
Boulder annual T record for comparison with our field measures
