Comments to Figure 7.29 on page 429 in the text book: The receiver (Ar in the figure) receives backscattered signals over a time interval T, which is equal to c*H, where c is the speed of light and H the pulse length. It starts sampling when the first backscatter from the leading edge of the pulse ("Top" in the figure) arrives, and stops sampling (from this pulse) a time T later. Consequently, the sampling will start as soon as the backscattered signal from the leading edge hitting the bottom of the target arrives, and it will stop as soon as the backscattered signal from the trailing edge ("Bottom" in the figure) hitting the bottom of the target arrives. At the time when the trailing edge hits the bottom of the target, and becomes partly reflected, backscattering of the leading part of the beam (between "Top" and "Middle" in the figure) will also have arrived at the bottom of the target. This backscatter comes from that part of...
On Tuesday (8/12) is the final group session this semester. I'll bring brownies! Maria

The midterm exam (written) on 28 October will be held in Auditorium 3 in the Geology Building from 12:15 to 15:15. It will consist of a combination of multiple choice questions and other types of questions, e.g., interpretation of equations or figures, discussion of methods including main equations, etc.
A slightly revised syllabus is found here
There will be no lecture on Tuesday 20 October. Instead, there will be a 1 hour lecture from 13:15 to 14:00 on Thursday 22 October in room 7.
We will go through the midterm from 2006 on Tuesday 27/10.
Thanks for a really nice trip to And?ya! Here's an article describing the different lidars at ALOMAR.
