Cold and snowy all day. Approximately 4 inches accumulation by evening. Some heavy riming this morning.
The weather conditions precluded much outdoor activity so the main focus was tidying up in the trailer, testing the Modular Profiler, checking data, and writing up notes. As expected there appears to be quite a bit of radio interference. The signal return from snow is very strong (also as expected) during which time the interference disappears, however it will be interesting to see how the data looks in clear cold conditions. We turned on RASS and that was working better than expected, despite the volume being low and there being lots of snow.
We wiped snow off the profiler antennas a couple of times, removing an inch or two of wet snow around 1830 UT and 2130 UT. The SNR seemed to improve a couple of dB each time. We also cleared out the RASS dishes around 2130. More snow fell later so there will probably be some further attenuation from that.
We also visited the ISFS trailer and connected up the Wind Lidar to the lidar laptop to check on its performance. There was moderate snow at the time, and the maximum range was less than 1 km (which was about the limit of visibility at the time).
