Includes atmospheric temperatures in the Jacobian.
The calculations are performed by (semi-)analytical expressions. Hydrostatic equilibrium (HSE) can be included.
The analytical calculation approach neglects so far refraction totally, but considers the local effect of HSE. The later should be accaptable for observations around zenith and nadir. There is no warning if the method is applied incorrectly, with respect to these issues. Note that the argument
hse
of this WSM only refers to the Jacobian calculation, if the model and/or retrieved atmosphere actually fulfils HSE or not is governed in other manners.The calculations (both options) assume that gas species are defined in VMR (a change in temperature then changes the number density). This has the consequence that retrieval of temperatures and number density can not be mixed. Neither any warning here!
The number of elements added to the state vector (
x
) is:n_g1 * n_g2 * n_g3
where n_g1, n_g2 and n_g3 are the length of GIN
g1
,g2
andg3
, respectively. Here empty vectors should be considered to have a length 1. The elements are sorted with pressure as innermost loop, followed by latitude and longitude as outermost loop.Author(s): Mattias Ekstrom, Patrick Eriksson
