Tool for interactive airborne ash detection in a SEVIRI image
24 Sep 2014 | Contributor(s):: shona mackie
This is a widget that can be invoked from IDL to display a region of SEVIRI imagery at thermal infrared wavelengths and discriminate airborne volcanic ash within it. Thresholds can be interactively set and applied across the image to create a dynamic ash mask. Thresholds are based on both a...
