They also measured the latent heat released over
land as the water vapor turned back into liquid water and fell as rain.
Not exact matches
The surface heat capacity C (j = 0) was set to the equivalent of a global layer of
water 50 m deep (which would be a layer ~ 70 m thick over the oceans) plus 70 % of the atmosphere, the latent heat of vaporization corresponding to a 20 % increase in
water vapor per 3 K warming (linearized for current conditions), and a little
land surface; expressed
as W * yr per m ^ 2 * K (a convenient unit), I got about 7.093.
Six types of instruments aboard Aqua are to scan through the atmosphere down to the surface, gathering the most detailed data ever on
water vapor in clouds, ice crystals in the air, evaporation,
water in the oceans, icebergs and other sea ice,
as well
as glaciers and snow pack on
land.
They move with the weather and eventually bring all the
water vapor with them to
land where it ends up coming down
as snow or rain.
These algorithms, developed for national and international operational and research satellite programs, convert sensor / instrument measurements into geophysical parameters such
as vertical temperature /
water vapor profiles, estimates of cloud amount, type and phase, and
land / ocean parameters such
as sea surface winds, net heat flux, and forest fire intensity / extent.
So the
water vapor feedback is
as much or more dependent of the available moisture of the
land mass being warmed or cooled.
AGW climate scientists seem to ignore that while the earth's surface may be warming, our atmosphere above 10,000 ft. above MSL is a refrigerator that can take
water vapor scavenged from the vast oceans on earth (which are also a formidable heat sink), lift it to cold zones in the atmosphere by convective physical processes, chill it (removing vast amounts of heat from the atmosphere) or freeze it, (removing even more vast amounts of heat from the atmosphere) drop it on
land and oceans
as rain, sleet or snow, moisturizing and cooling the soil, cooling the oceans and building polar ice caps and even more importantly, increasing the albedo of the earth, with a critical negative feedback determining how much of the sun's energy is reflected back into space, changing the moment of inertia of the earth by removing
water mass from equatorial latitudes and transporting this
water vapor mass to the poles, reducing the earth's spin axis moment of inertia and speeding up its spin rate, etc..
In all of these simple models, we assume the atmosphere to have a volume
as fixed
as a bathtub, we assume that the atmosphere / ocean system is a closed system, we assume that the incoming radiation from the Sun is constant, we assume no turbulence, we assume no viscosity, we assume radiative equilibrium with no feedback lag, we take no account of
water vapor flux assuming it to be constant, no change in albedo from changes in
land use, glacier lengthening and shortening, no volcanic eruptions, no feedbacks from vegetation.
Early work at GFDL relating to carbon focused on CO2
as a greenhouse gas and it's potential for doubling in response to human activities, through
water vapor and other atmospheric feedbacks in the context of latitudinal,
land - sea and other inhomogeneities influencing climate (e.g. Manabe 1968, 1986, 1987).
