A mostly cool cloudy & calm morning in the valley.  The fog/cloud lifted around midday and it was partly sunny although windy during the afternoon.

We were mostly working at ISS3 Sedgwick today.  We took the profiler antenna apart, temporarily removing the clutter screen and radome to clean off the antenna, which was covered in a thick layer of dust and dirt.  We had wondered if this was affecting the performance of the antenna, however as John will report elsewhere, is wasn't clear if this helped.  Taking it apart did allow us to inspect the surface of the antenna and it was noticed that the panels are a little warped and cracked which may explain the problems we are having with it.  We mostly reassembled the antenna this afternoon, although John is making repairs to still one of the clutter screen panels so the profiler is missing that panel for now.  Liz also replaced one of the relays that had been sticking earlier.

Isabel is making good progress on the data flow and many plots are appearing on the web. The first are now available at the SWEX ISS web page with more to follow soon.   Erik's wind plot visualization tool plotting up the 449 MHz profiler and the link to that was also added to the web page.

We replaced the main SSD disk drive on the wind lidar yesterday with a new drive that arrived from Vaisala.  This included a software update that should improve the stability of the system.  It seems to be working well so far, however the file names are misnamed ("WCS999951_" instead of the usual "WLS200s-181_") which is causing a few problems with the downstream processing for now.

Cleaning off the antenna at Sedgwick and reassembling the clutter screen afterwards.
