A class for gridded data of the geoid.
Initialization
| Initialization method |
Description |
x = SHGravCoeffs.geoid() |
Initialize using an SHGravCoeffs class instance. |
Class attributes
| Attribute |
Description |
geoid |
SHGrid class instance of the geoid. |
gm |
Gravitational constant time the mass of the body. |
potref |
Potential of the chosen geoid. |
a |
Semimajor axis of the reference ellipsoid. |
f |
Flattening of the reference ellipsoid, f = (a - b) / a. |
omega |
Angular rotation rate of the body. |
r |
Reference radius of the Taylor expansion. |
order |
Order of the Taylor expansion. |
units |
The units of the gridded data. |
lmax |
The maximum spherical harmonic degree resolvable by the grids. |
lmax_calc |
The maximum spherical harmonic degree of the gravitational potential used in creating the grids. |
nlat, nlon |
The number of latitude and longitude bands in the grids. |
sampling |
The longitudinal sampling scheme of the grids: either 1 for nlon = nlat or 2 for nlon = 2 * nlat. |
epoch |
The epoch time of the gravity model. |
