A calm, cold, and clear morning, increasing high clouds during the afternoon.
The first IOP ran last night and this morning, officially ending at local noon. No fog was observed, although there was some light haze which fits with the high aerosol counts reported by Gannet and the smokey air forecast from NWS. All the ISS instruments worked well, although we were still having lingering issues:
Sounding computer: rsync problems with the data manager computer meant that data wasn't transferred during the IOP, however Isabel managed to get it working this afternoon. The surface met ingest isn't working yet, although Gary has some suggestions which I will try tomorrow. Installed open office on the sounding computer this afternoon so that we now will have a sounding log. I am in the process of gathering the missing information.
CL61 Ceilometer: after the power outage yesterday, the CL61 restarted with the wrong time sync and generated files dated 2010. It should be possible to recover this data.
The wind lidar ran well with the high aerosol levels, seeing 4 to 5 km in the low-level scans, and did a good job of documenting the variable drainage flows during the night.
At the ISS1 site, the Modular Profiler ran well producing winds up to about the 3 km level, and RASS up to the 1.5 km level. At 22UT in winds mode, the amplifer 50V supply was drawing 3.04A and the 31V supply drew 1.76A. In RASS mode the 50V supply drew 3.38A and the 31V supply drew 1.915A.
