AHATS daily status 6/28/08
Staff: Maclean, Horst, Tong, Khoung
Summary: Replaced 3m profile sonic yesterday. Chenning and Khung working
on completion of pressure sensor deployment. Currently no data from
downwind 1 and profile adams; radio down but should have local data storage.
Gordon recycled power on the transmitter, but we later discovered that the
downwind-1 and pressure-1 adams are not transmitting. Gordon found that
the adams were not getting their internet addresses due to outages of
the wireless network.
Good wind direction: For the period 6/25 17:00 through 6/28 11:45, we have
24 hours 35 minutes of data periods of length 20 minutes or longer
with wind directions from 195-355 degrees. This includes 8 periods of
length greater than one hour. Note that the daytime periods may be
compromised by work on the array, e.g. installing the pressure sensors.
