Due to the current gap in continued funding from the U.S. National Science Foundation (NSF), the NSF Unidata Program Center has temporarily paused most operations. See NSF Unidata Pause in Most Operations for details.
I've got a sat pic (from a server under "Images") on the surface, and a colour-shaded plot of theta-e at 850 hPa from the GFS above. I restrict the visible range of the theta-e to a value so only areas above a certain value are shown (to illustrate a plume event). However areas with theta-e below my range appear black, rather than showing through the sat pic below. Am I missing something simple, is this is intended behaviour, or is it a bug? Dan
