The day started off warm and mostly sunny, but the wind picked up, more clouds arrived and the temperature dropped as a cold front moved in. Sundowner winds are forecast for the next few days, but the IOP that had been planned for tomorrow was delayed another day in the hopes of catching some more interesting wind patterns. Currently the IOP is proposed for Wednesday. Steve left today and Lou will be starting tomorrow.
Jacquie and Matt went off to ISS2 and some of the ISFS sites in the valley. I had meetings and worked at ISS1 today where I did some tidying up, further work on the lidar and set up a couple of backup disks for data. Jacquie and Matt came back to ISS1 for a class in running the lidar and we did a few more hard target scans to check the orientation. A couple of problems cropped up later in the day:
The ISS3 profiler computer appeared to go down, presumably because of the same UPS problem we had seen previously. The computer isn't responding to pings from the ISS3 DM so must have powered off. We will go out to Sedgwick tomorrow to investigate.
The ISS1 data manager froze late afternoon just web apparently while browsing on the field catalog and was unresponsive on the main terminal. I could get to it by sshing from the profiler computer, but killing the browser processes didn't fix it so we did a reboot. Unfortunately after rebooting, a network configuration problem occurred and it couldn't connect to the LAN or outside internet. Eventually we got Gary on the case and he figured out that the two network port were swapped after rebooting for some reason and talked me through getting it back online (see his blog entry for more details). Late in the day the wind picked up further and started blowing loose ISFS items around so had to secure those.
