---------------\-
diag: ok, 6u noticable spiking in daytime, up to .06, ok at night
samples.sonic: ok?
spd: ok, \ +/\- 20 cm/s, 3u,4u seem highest in day, they're best exposed to the NE in 'bad' cond\
itions.

Wiki MarkupDownwind Lower \ [,select.b\] \
-----------------------\-
Relatively large differences with east winds.

diag: ok, 2b spiking in daytime some, upto .05 occassionally (Birds, spiders?)
samples.sonic: ok
spd: ok, +/- 5 cm/s, with 1b upto to 1m higher, and 2b next in daytime with NEearly winds
dir: ok, new boom angles improved things at ~19z last night, but 1b, 10b still appear out.
w: ok, +/- 10 cm/s, pitched up a bit (we tightened it a bit too much)
tc:  ok, +/- 0.3 deg, biases up to +/-0.6
w'w': ok, +/- 0.01 m^2/s^2  (30 min avg for second moments)

-----------------------\-

diag: ok, misc brief spikes, more likely birds than the notes above
samples.sonic: ok
spd: ok, +/- 50 cm/s, 3t much higher up to 1.1-5m during daytime (NE winds)
dir: ok, +/- 2 deg, need boom angles
w: ok, +/- 10 cm/s
tc:  ok, +/- 0.4 degC, offsets up to 0.6 degC
w'w': ok, up to +.15-0.2 m^2/s^2 in day (30 min avg for second moments)
