Hi Curtis- Sorry for the delay in responding. > Institution: Department of Geography, Kansas University > Package Version: 2.1 > Operating System: Windows XP > Hardware Information: Java: home: C:\\Program Files\\IDV_2.1\\jre version: > 1.5.0_06 j3d:1.3.2 fcs (build12) > Inquiry: An error has occurred: > Creating display: Contour Plan View > org.python.core.PyException The problem is that the IDV does not handle derived quantities that involve derivatives when the domain of the grid is straight lat/lon. This is listed in the known bugs, but probably not as evident as what your problem is. With lat/lon grids, we need to account for the decreasing spacing of longitude lines with increasing latitude.
