Name
CL_mod_expDensity — Exponential density model
Calling Sequence
[ro]=CL_mod_expDensity(altitude[,prctl,h_ro])
Parameters
- altitude:
altitude [m]
- prctl:
(optional) percentile level. Possible values are 1,5,33,67,95,99 and 100 (default is 100)
- h_ro:
(optional, exponential model parameter) inverse of scale height (beta) [km^-1] (default is 0.0153)
- ro :
air density [kg/m^3]
Description
-
This function returns density value (ro) corresponding to a given altitude according
exponential model and with a confidence index given by input percentile (prctl). Other parameters
of the exponential model (reference density and altitude) are function of the input altitude and prctl values.
