7/26/11
From plots of vertical velocity (mostly), wind direction, and pressure, I deduced the following times at which the masts were lowered and raised. I entered these times into the sonic qc files (in order to delete data while the mast was down), adding 5 minutes to the raising time to allow for attaching and adjusting the back guy wire.

These dates and times confirm my records. I have one record that another student is holding in their notebook, which has to be the July 15 entry. So I would agree that the dates and times suggested for the sonic qc files are appropriate. Are periods also filtered out for during/immediately after heavy rain storms, like the one we had this morning around 8:00?
