Summary: Gordon is working on the software to obtain calibrated fast pressure
data. An initial look at the frequency data suggests that the data from the
pressure sensor is too noisy. We are working on cleaning up the signal.

Good wind direction: For the period 7/1 13:00 through 7/3 13:00, we have
28.33 hours 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 and equates to good periods 59% of the time.
Sorted by stability, there are 14.5 hours of stable stratification
(<w'tc'> < 0) nad 13.75 hours of unstable stratification.

Staff: Maclean, Horst, Khoung, Brown; Chenning left this morning
Summary: Gordon found low voltages in the adams, so has been improving the
battery charging over the past few days. These changes have improved the
power in the adams and have reduced the number of outages we have been
having.
We have been measuring the array dimensions and still need to measure
the sonic azimuths.
We are essentially starting ops at 13:00 on July 1, because of
the change in sonic heights in the upwind array and the late completion
of the pressure array. Chenning and I have agreed on the following
tentative schedule for configuration changes.
Configuration 1 (height = 3m, spacing = 4m): July 1-10 (10 days)
Configuration 2 (height = 3m, spacing = 1.29m): July 13-20 (8 days)
Configuration 3 (height = 7m, spacing = 1.29 m): July 22-29 (8 days)
Configuration 4 (height = 7m, spacing = 0.43 m): August 1-9 (9 days)

AHATS daily status 7/01/08
Staff: Maclean, Horst, Tong, Khoung, Brown
Summary: Chenning and Khoung completed the pressure sensor deployment this
morning by connecting the upper 5 sensors to the reference cylinder.
We decided to lower the sonics in the upwind array by 0.5 m to match
the height of the lower sonics in the downwind array. This will allow
a more accurate combination of the cross-array gradients and the
between-array gradients to calculate the streamwise and crosswind gradients.
Good wind direction: For the period 6/25 17:00 through 7/1 16:35, we have
54.25 hours of data periods of length 20 minutes or longer with
wind directions from 195-355 degrees. This includes 13 periods of length
one hour or greater and equates to good periods 38%(!) of the time.
Note that the daytime periods may be compromised by work on the array,
e.g. installing the pressure sensors.

We are essentially starting ops at 13:00 on July 1, because of the change in sonic heights in the upwind array and the late completion of the pressure array. Chenning and I have agreed on the following tentative schedule for configuration changes.
Configuration 1 (height = 3m, spacing = 4m): July 1-10 (10 days)
Configuration 2 (height = 3m, spacing = 1.29m): July 13-20 (8 days)
Configuration 3 (height = 7m, spacing = 1.29 m): July 22-29 (8 days)
Configuration 4 (height = 7m, spacing = 0.43 m): August 1-9 (9 days)
From 12:17 until 12:55, July 1, Gordon and Tom lowered the upwind sonics by 0.5 m to match the height of the lower downwind array.
Chenning and Tom finished measuring the array dimensions this morning, July 1, from around 9:30 until 10:20 am.

mean upper sonic height = 2.664+0.053 m (total mean height = 4.25 m)
3/17/09, TWH: Why did I use 5.5 cm rather than 5 cm as the height of the sonic above its boom?
12/14/09, TWH answer: To account for thickness of saddle on sonic boom; perhaps 5.3 cm would be better

Upwind check dam
The sonic 7u (upwind array) is 40m downwind of the check dam along azimuth 131 deg magnetic.
The check dam is parallel to azimuth 258.1 deg magnetic.
The sonics on the profile tower are 35m downwind of the check dam.
Profile tower
Reference height agl = 1.52 m
Sonics are 5.3 cm above top of boom; SHT inlets are 37 cm below top of boom
Note that often we could not place sonic and SHT boom mounts at the ideal heights

No data was being sent from pressure2, and local storage was not being written to. System was up, could log in over the network, and the dsm process was running.
data quit at 12:26 UTC, Jul 1. Restarted it with adn/aup at 13:26 UTC.

Due to the low voltage at the profile tower, we cobbled together a power system for it.
Prior to adding the supply, the voltage at the inside of the power interface panel on profile was 9.9V.
Charging system consists of a 12VDC power supply (white rectangular cube), PAM charge controller (didn't note which kind) and a battery, all in a white cooler. A second separate battery is also connected. Strung a new AC extension cord to this system. Left the cooler lid propped open. Will have to watch that this doesn't overheat.
Voltage a the profile power interface panel after adding the charger was 12.1 V.
The hope is that this will also increase the voltage levels at downwind1.
Checked voltages at downwind1 charge controller:
J3 (DC in): 12.8V
J2 (to battery): 12.2V
J1 (load): 12.1V
At unused output from charger: 13.5 V.
Inside downwind1 interface panel: 11.1 V (still seems low)
