The temperature Profiler is worked out
in the below. The Profiler determines the temperature profile as
seen by light path (Ray Path Temperature Profile: RPTP), with
that in hand one can determine the temperature gradient the
light sees as it travels its path and thus also the refraction.
A sample of elevation of the light path and the ground
(derived from HeyWhatsThat) can be seen below (using the
light path between The Hill and
Pladda lighthouse). HeyWhatsThat can provide numeric output
(instead of a picture) of the elevation of the light path (line
of sight) and ground.
By changing the scale, the lower elevations can be seen in more
The height-temperature profile at several locations can be
estimated (using e.g. balloon sondes or using a profile that is
composed of [empirical derived] profiles as described in this link and this link).
The Profiler is now building the temperature seen by the path
using likely boundary layer
height-temperature profiles at certain points. So by breaking up
the whole light path in segments, each starting and ending with
(possible) different height-temperature profiles:
