A sunny warm day. ISS setup so mostly complete. Although there are some minor tasks yet to be done, the only major outstanding issue is the ISS3 wind profiler at Sedgwick. It is running however still has the clutter signal problem dominating the atmospheric signal. We are working on a plan to repair the system (probably involving tuning the local oscillator to better match the antenna) and will return with the necessary equipment to do this work the last week of March. John, Gary and I did some tidying up at ISS1 this morning and flew back to Boulder this afternoon. I will be returning on March 28 and John and/or Liz may be flying back sooner to work on the profiler. Thanks to the rest of team (John, Liz, Lou, Gary and Dexter) for their hard work during the setup.
