> HYSPLIT deposition contours with no corresponding air concentration contours. Why?
I found a case where there are deposition contours where there are no corresponding air concentration
contours. Why?
Although it appears you have deposition where there is no air concentration, this cannot be the case.
If you look at the minimum air concentration for the plots, you will see that it is much smaller than
the minimum contour shown. Normally the concentration plotting program automatically scales the
contour interval and these smaller contours would have been shown. However, due to the popularity
of the concentration animations, we set the default plot to fix the contours, so that the same
color would represent the same concentration with each frame. Therefore on subsequent frames
the air concentration plume appears to dissapear while deposition continues to occur. You can
change this default to have the contours change from plot to plot.
