How do I go about defining the COAMPStm region so that the minimum map scale factor is closer to 1.0?
Map projections used in the mesoscale model usually have large distortion when the point is far away from the true latitudes (the latitudes where map scale factor is 1). One can use a smaller domain or try to change the value of the true latitudes “phnt1” and “phnt2” variables. The variable “phnt2” is only used for Lamber Conformal projection.
