On Husband's work

Husband is asked many times what he does, since he doesn't teach much, most of his work being split between Administration and international ecological research. To lay people he says things such as "I enjoy seeing grass grow remotely from space" and other such cute phrases.

Well, yesterday he sent me this link, of a paper published with one of his doctoral students. There is a video-abstract as well. I understand next-to-nothing about it, but I thought maybe my dear readers would... or at least see what kind of research he works on.
