Constants

Mathematical, physical & scienfitic constants.

All in scientific units.

Pint is still figuring out how to properly deal with constants: hgrecco/pint#1078 Until then, I will keep them here.

Na	Avogadro number [1/mol]
kb	Boltzmann constant [J/K]
rho_w	Density of water [kg/m^3]
Gamma_d	Dry adiabatic lapse rate [K/km]
Rd	Gas constant for dry air [J/kg/K]
Rv	Gas constant for water vapor [J/kg/K]
g	Gravitational acceleration [m/sec^2]
cp	Heat capacity of dry air [J/kg/K]
c_l	Heat capacity of liquid water [J/kg/K]
cv	Heat capacity of water vapor [J/kg/K]
L_f	Latent heat of fusion [J/kg]
L	Latent heat of vaporization [J/kg]
L_s	Latent heat of sublimation [J/kg]
h	Planck constant [J*sec]
R_earth	Radius of the Earth [km]
epsilon	Ratio of gas constants [#]
c	Speed of light [m/sec]
sigma	Stefan-Boltzmann constant [W/m^2/K^4]
Rstar	Universial gas constant [J/K/mol]
