Howdy all!
I see in the CF document:
Atmosphere sigma coordinate
standard_name = "atmosphere_sigma_coordinate"
Definition:
p(n,k,j,i) = ptop + sigma(k)*(ps(n,j,i)-ptop)
where p(n,k,j,i) is the pressure at gridpoint (n,k,j,i), ptop is the
pressure at the top of the model, sigma(k) is the dimensionless
coordinate at vertical gridpoint (k), and ps(n,j,i) is the surface
pressure at horizontal gridpoint (j,i) and time (n).
The format for the formula_terms attribute is
formula_terms = "sigma: var1 ps: var2 ptop: var3"
Where "var1", "var2", and "var3" are the names of the sigma, surface
pressure, and ptop variables.
My question: is the ptop variable always a scalar variable?
Thanks!
