Ops 2/17

It's a beautiful day in Gothic! Sunny, calm, sparkling, and the warmest -10c I've ever felt.

Before we headed out to the site this morning we checked data, I formatted the new lidar USB sticks with guidance from Ethan, and we stopped by the Salamander room to get some serial numbers. As we were skiing out to the site we passed Danny and Eli coming back from digging a snow pit. At site the top of the barrel is just about level with the snowpack.

We got harnesses on and started at tower D, where Tony climbed to clean the radiometers and get the mote IDs. Radiometer cleaning at D was between around 12:05 and 12:10 local. There were two motes at the top of the tower. One was SN6 but ID was just a dash (is this the bluetooth mote for the mobile tsnows?) and the other was ID39.

At D DSM serial numbers are 209 (power box) and 230 (dsm).

At C DSM serial numbers are 210 (cb), 250 (cu), and I couldn't see any of the higher ones (we may borrow Eli's binoculars tomorrow). The power box didn't have a serial number, or at least I couldn't see it from the ground.

At UW DSM serial numbers are 211 (power box) and 215 (dsm).

At UW we cleaned the NR01 at 12:35. We power cycled Ethan's lidar by opening the power box and disconnecting and reconnecting the lidar power supply cable (helpfully labeled). Ethan says he can connect to the lidar now, but it's giving messages about a mechanical error and may be out of commission for the rest of the project. Since that's the case, and since that lidar currently had a smaller USB stick installed, Ethan told us not to swap the USB for that lidar (that's lidar pi 3). We did swap in a new USB stick for the other lidar, pi 8.

Since we still had a fresh USB stick we went back to D and swapped it out with the one that had been in pi 6. We will have to swap the USB stick in the other pi at D tomorrow.

Headed back to Gothic around 2. Stopped in at Maroon to visit Danny, to drop off the lidar USB sticks for him to upload to Ethan's hard drive. The mote Danny and Eli have for the mobile tsnows is ID49, and it's v2.8. Took a little ski further up the road to Schofield Pass, but the snow is getting pretty sticky in the sun. We have neighbors in Lower Crystal tonight, a party of cross-country skiers.

Plan for tomorrow is:

• Swap out 3 more lidar USB sticks (will have to get at least one back from Danny in the morning). One at D and two at UE.
• Check power to CSAT3BH (couldn't do that today because the multimeter wasn't in the barrel, but we've gotten it back from Danny).
• Get some more DSM serial numbers, from UE which we haven't visited yet and possibly more from C.
• If we get all this done quickly, we've been considering leaving tomorrow, but we'll see how it goes.
