epygram.profiles — Functions on vertical profiles
This module contains functions to:
 to convert vertical coordinates systems from the one to another;
 compute air specific gas constant R according to specific humidity
and hydrometeors.
 to plot vertical profiles.
Conversion

epygram.profiles.hybridP2fluxpressure(A, B, Psurf)
Computes the pressure at flux levels defined by hybridpressure
coefficients. Coefficients are assumed to define flux levels.
 A = table of A coefficients
 B = table of B coefficients
 Psurf = surface pressure in Pa.
A and B must not contain the first coefficient (A=B=0.)
Returns a table of pressure.

epygram.profiles.hybridP2masspressure(A, B, Psurf, vertical_mean)
Computes the pressure at mass levels defined by hybridpressure
coefficients. Coefficients are assumed to define flux levels.
 A = table of A coefficients
 B = table of B coefficients
 Psurf = surface pressure in Pa.
 vertical_mean = kind of vertical averaging
A and B must not contain the first coefficient (A=B=0.)
Returns a table of pressure.

epygram.profiles.hybridH2fluxheight(A, B, Zsurf, conv2height=False)
Computes the altitude at flux levels defined by hybridheight coefficients.
Coefficients are assumed to define flux levels.
 A = table of A coefficients
 B = table of B coefficients
 Zsurf = surface altitude in m.
 conv2height True to compute height instead of altitude
A and B must include the underground level
Returns a table of altitudes.

epygram.profiles.hybridH2massheight(A, B, Zsurf, conv2height=False)
Computes the altitude at mass levels defined by hybridheight
coefficients. Coefficients are assumed to define flux levels.
 A = table of A coefficients
 B = table of B coefficients
 Zsurf = surface altitude in m.
 conv2height True to compute height instead of altitude
A and B must include the underground level
Returns a table of altitudes.

epygram.profiles.flux2masspressures(pi_tilde, vertical_mean, Ptop=0.0)[source]
Converts pressures at flux levels to mass levels.

epygram.profiles.mass2fluxpressures(pi, vertical_mean, Ptop=0.0)[source]
Converts pressures at mass levels to flux levels.

epygram.profiles.flux2massheights(H_tilde)
Converts altitudes at flux levels to mass levels.

epygram.profiles.mass2fluxheights(H)
Converts altitudes at mass levels to flux levels.

epygram.profiles.pressure2altitude(R, T, vertical_mean, pi=None, pi_tilde=None, Pdep=None, Phi_surf=None)[source]
Converts a pressure profile to masslevels altitude (= height above ground
if Phi_surf == 0).
The pressure can be given at mass levels (pi) or flux levels (pi_tilde),
or both (assuming they are consistent), with unit: Pa.
 R = table of R = specific gas constant (J/kg/K)
 T = table of Temperature (K)
 vertical_mean = kind of vertical averaging
 Pdep = table of Pressure departure: PPi, where P is the hydrostatic
pressure and Pi the NonHydrostatic pressure (Pa).
 if Hydrostatic (default)
 Phi_surf = surface geopotential (J/kg)

epygram.profiles.hybridP2altitude(A, B, R, T, Psurf, vertical_mean, Pdep=None, Phi_surf=None, Ptop=0.0)

coefficients. (= height above ground if Phi_surf == 0).
