I know of no climate scientist who would do experiments
fixing land temperatures and observing the atmospheric response, and with good reason.
Not exact matches
Only an amateur with no concept of the material (Stokes) derivative and time - series aliasing would conclude that lack of serial observations, such as provided by
land - station data, of diurnally varying
temperature at
fixed oceanic locations is «not a problem.»
From his blog, post # 11: «if you
fix the
temperature, as over the ocean here, you have to let the flux adjust to be consistent with that
temperature — if you
fix the flux (which is effectively zero over
land) you have to let the
temperature adjust to be consistent with that flux.»
With respect to the
temperature, I might agree that choosing 1970 is a cherry - pick if you are talking about the
land record in general, but looking at the whole record seems to be the
fix for that, not looking only at 1940 to 1970, another, though opposite effect, cherry - pick.
OTEC plants can be
land - based, «floating» (offshore
fixed plants), or «grazing» plants that are allowed to drift through the areas of the ocean with high
temperature differences, storing the energy they produce as liquid hydrogen.
This effective radiative forcing is the climate sensitivity calculation that incorporates
temperature responses in the troposphere and
land surface that are rapid compared to the ocean
temperature response, using
fixed - sea surface
temperature experiments.
Shine et al. not only
fix sea surface
temperatures, but also
fix land surface
temperatures because
temperatures over
land and ocean are related.
Cartoon comparing (a) Fi, instantaneous forcing, (b) Fa, adjusted forcing, which allows stratospheric
temperature to adjust, (c) Fg,
fixed Tg forcing, which allows atmospheric
temperature to adjust, (d) Fs,
fixed SST forcing, which allows atmospheric
temperature and
land temperature to adjust, and (e) DTs, global surface air
temperature calculated by the climate model in response to the climate forcing agent.»
The oceans were given an infinite heat capacity (
fixed temperature), while
land and ice had zero capacity.
It defines ERF similarly to Hansen's Fs, but with no adjustment made for the change in
land temperature (which is modest when SST is
fixed), and notes that ERF can also be estimated by regression, as for Fs *.
