[gradsusr] Question on the use of PDEF for Lambert Conformal Conic mapping

[Huddleston, John]

Hi

Attached are two images of the same data, one is a close up view and one is a view from space.

The grid was made by taking the Lambert Conformal Conic grid in meters and projecting it to Mercator for display in Google earth.

The sample data set was plotted with GrADS using PDEF to transform it again for display in Google earth.

The view from space looks correct.

The close up view shows the GrADS grid cells vertically up and down and they do not match the LCC grid.

Is this the correct behavior for the plot?
