We can use a polynomial function to fit the
observational data and then
|
|
use this function to generate data on regular grids.

In meteorological applications, up to thrid order polynomial have
been
|
|
|
used. But usually, quadratic equation is sufficient for most
purpose:

The problem now it to determine the values of the coefficients: a1,
|
|
|
a2, …., and a6.

If we have 6 observations of h, then we can determine the 6
|
|
|
coefficients in the quadratic polynomial function.

q |
We can then use the polynomial function for gridding purpose.
