A warmer (0C - 4C) but overcast day with occasional snow flakes.  Lou arrived last night.

At the profiler site, cleared the snow around the amplifier enclosure, opened it up and disconnected the pipe heater since the electronics seem to be keeping it warm enough (around 18 - 20C, whereas previously it had been just above freezing).  The profiler is still running an alternating 100-meeter and 150-meter mode (both with 4-bit completmentary phase coding) to test which might be better for the project. The 100m mode appears to be providing winds down to about 500 - 600m, whereas the 150m mode only gets down to around 800m.  The upper level is highly variable (today 3-4 km without the dry layer break we saw yesterday), although there does seem to be an extra 100 - 200 m coverage with the 150m mode.  Today the 100m mode drew about 3.25A on the main 50V supply, and the 150m mode drew about 4.54A.

At the lidar site, more precisely leveled the lidar by making fine adjustments on the lidar itself as well as with the lidar trailer jacks.  Now the pitch is approximately within 0.01 deg of perfect level and the roll about 0.015 deg.

We drove down to the Salt Lake City area to pick up a cargo trailer that we will use for the sounding system.  Unfortunately the snow plower operator we hoped would clear the road into the site gave up half way through the job, so we can't yet get the trailer into position.  Apparently he intends to retry tomorrow although with more snow in the forecast there is a concern about whether it will be possible to get it in there.
