Summary: Picked up parts for T&RH solar shield assembly for repairs.

Where: Tonzi
When
Who: Ted Hehn
This week I was able to mount the PC enclosure, the licor enclosure, the
sonic and licor mount bracket (with anti fall stop) short one quick
coupler, install the power line from the tower base to the top (with
junction boxes purchased in Jackson on my card). It is a clean installation
done the right way that will last the duration of the 2-3 years remaining
on this grant.

Having to leave a day early to supervise the Beackman crew precluded me
from performing the planning and construction of the net par mount bracket
and repairing the T&RH solar shield mount assembly. These tasks are not
easily performed in the field and consequently I removed the tray apparatus
from the top of the tower and brought it back with me. I believe it will be
necessary to remove the tray walls (too much reflection) and expanded metal
portion attached to that apparatus to facilitate mounting instruments. The
expanded metal portion can then be modified to function as a trap door on
the upper most section eliminating any possibility of falling down the
stairs while working on top. Are you OK with that?


On 24 Apr I changed the execution interval on the TONZI 23x from 2 sec to 6
sec - the delays that were used in that program to wait until the probe
readings stabilized totaled 5 sec so data loss resulted from the 2 sec setting

I also changed the execution interval on the TONZI CR 10 from 2 sec to 4
sec for the same reason as above.

A precip guage was also added at the Tonzi site - data was appended to the
end of the output file in units of inches
