Low overcast in the morning, burned off to clear by noon.
Started by visiting DC, which had been off the net for 12 hours by the time we checked data. At DC there was no power at the outlet on the fence and the batteries were dead, so presumably the power failed a couple days ago. We talked to one of the people at the stables, who told us the breaker for the power outlet has been tripping since last week, and lately is tripping immediately after resetting it. We unplugged our power cord from the outlet and tried the breaker again, but it still tripped, so we think the problem is somewhere between the breaker and the outlet, not in any of our equipment. Dan is going to talk to the electrician about it. We replaced the batteries at DC with fresh ones, which got it going again. We'll probably have to swap batteries here every couple days until we get the power to the outlet fixed.
After that I took Liz to the last two satellite sites of our tour:
- CC: measured HRXL height
- DC: measured HRXL height. The EC100 box was open when we got there, so either we left it open last time we were there or someone else came to investigate. Either way the EC100 has been reporting data the entire time, the lights are all green, and it doesn't look like any snow got into the box.
This afternoon I visited PRS while Liz did the sounding. I got HRXL height, compass boom angles, one more EC100 serial number, and site photos. Refilled the gas in the generator since I was thinking about it. Got prst back on the net since I was there anyway, but it was just a modem problem so it would have come back up. I did some more digging into the port 7 problem on prsr but didn't really figure anything out, see Jira for more details: https://jira.ucar.edu/browse/ISFS-529
We also got the soil corer working again by doing some filing so the hole in the handle is now large enough to fit the weight rod again.
Talked to Sebastian today, who was wondering about thermocouple status. Last I checked only the 32m thermocouple at PRS was broken, out of the ones Sebastian didn't remove before the snow the other night. Sebastian put all the thermocouples back that he removed the other day (2m and below). We'll want to lower the tower at PRS to replace the 32m thermocouple before the next IOP, which sounds like will probably be starting at noon on Monday.
Not much else to report data-wise. I used usbreset to get the HRXL at dcsr reporting again this morning. As of now dcst is off the net, but if it's just a modem problem it will probably come back up in half an hour. The tsoil at dcs stopped reporting this afternoon, so I tried power cycling the mote with pio, but that didn't bring it back. We'll try to head over there tomorrow.
