GMT Time check: ASTER - 20:29:27, GMT 20:26:00
Thus, aster is 3 min, 27 sec ahead of coordinated universal time.
The monocle compass/rangefinder was set to 1:28 pm, local two minutes later,
so it should be correct.

Author should default to last author in the session.
Type already defaults this way, which is not as desirable since
we mostly enter all comments of one type into one comment per
session. For example, this comment really has two pieces of
information - one suggesting a default for author and another
suggesting a lack of a default for type - which are being entered
as one. In this session, I might next comment on the weather or
the performance of a sensor (though I won't since I am logged in
remotely!), which would require totally different types.

It had a segmentation fault, but all other processes look okay.

Strange vertical velocities this morning
There have been some wild w changes - up to +/- 1 m/s changes in a few seconds.
I guess these are isolated plumes getting started just after sunrise.

Winds often calm
During the last hour, the winds have often been calm (props stalled). This
period can be used for sonic zero checks. Also, believe it or not, the
temperature profile is unstable (despite the overcast sky) so this should
be free convection data. I would interpret fluxes, though, with a grain
of salt.

PARAMETER PROJECT LOOKS GOOD!
I played around with metalog to get it to
default the project name correctly. It seems to be
working now. What I did was delete all params.* files.
Logbook then created a new file with the correct project
name. Maybe this file has something to do with it.

LOGBOOK PROJECT FIX FAILED:
The fix to logbook project default has
failed. It almost seems like logbook does an update
on its own and graps some past file with FLAT90 in it.

Status report at 03:00
Checked wind, temp and cockpit displays.
Vaisalla and Rotronics have different grey traces over the last
few hours. The humidity at the site is varying quite a bit.
PSP.in is not showing on the trace.
Cannot graph the means. No match.

Winds picking up, a bit of spiking on ncar.comp sonic, minor.
The minimum in the Tdry at 7m looks natural
psp.in back on scale
Pitch and roll giving sinusoidal signal, much slower than frequency of tower
Data system OK

zo analysis
I've fitted several "near-neutral" cases for zo (all 1 hour long):
using displacement heights:
Day Beg Dir zo err disp z/L
cm cm/s cm
48 16 163 4.7 1.0 10 -0.015
55 17.5 18 2.6 2.1 20 -0.025
56 22 338 2.4 0.8 20 -0.011
61 00 67 6.9 2.0 00 0.005
65 13 336 2.7 1.4 15 0.013
71 06 5 3.2 2.1 10 0.002
73 21 140 3.2 2.1 20 -0.085
Obviously, a good value for zo for northerly cases is 3cm and disp=20cm.
Also, other directions are different.
