Blog from December, 2010

12:30 - 12:45

Measured sonic height and boom angle.

height - 3.27m

boom - 78.0 (ss), 78.3(cg) magnetic (boom pointing west)

11:00 - 11:30

Station was down this morning. A power recycle started up the station.

Measurement of the sonic height from ground to pivot bolt is  85cm

10:30 - 10:50

Reprogrammed router at base and installed. Would not work until a full power recycle on DSM.

Able to get into DSM via wifi and cell.

Router and cell units are #3

8:45 - 9:15am

Visited this site due to no transmission.  Found a fault light on charging system.  Unplugged everything from charging unit...this includes batteries.  It seemed to reset charger and dsm was back up.  The Verizon router was not syncing.  Could not talk to the dsm via wifi or cell modem.  Removed router and bringing back to base trailer to re-install settings.

Hiland and Eslope off the air early this morning. Low battery voltage may be the reason.

Will take a set of fresh batteries to each site.

13:30 - 14:30, Dec 21

Replaced Tsoil probe.

Lowered mast to clean krypton, clean solar, and clean radiometer

trailer test: brought probe back to trailer and did a visual check.

There was no sign on moisture in the connector. Did a simple ice

bath test and the probe was reading high. Will take back to Boulder.

   twh (3/1/11): high-rate data indicate kh2o cleaned at 14:03

                           high-rate u,w suggest mast down 13:59 - 14:05, but light winds make this ambiguous

          (3/3/11): high-rate pressure data confirm 13:59 - 14:05

12:00-12:15

Replace router with a new unit with the correct configuration.

This was the original router at ABC which was removed earlier today

router

10:30 - 11:00

Since power was still low at 2 decided to change out the DSM. Before making the change we use

the meter to verify volatge readings. The result was we found a loose connector on the main

power cable going from the power switch to the power panel board. Everything looks ok now.

We also changed the the router since we could not communicate withe DSM via WIFI or cell.

According to Gordon we still need to make another change in the router firmware.

Snow removal at solar panels and radiometers.

12:05 - 12:30pm

Sonic Angle = 85.8deg

Connected to ETI and noticed the temperature compensation was turned off.  Turned compensation on.

Cleaned off solar panels.

11:16 - 11:36am

Mast height(sonic) = 68.9cm

Sonic Angle ?= 253.5deg.

Looked at Tsoil.  Seems to be reading high.  Noticed ground was snowy except over soil probes.  Everything seemed fine.  Will ask Joe to bury new probe.

Cleaned off solar panels and radiometers.  Covered in snow.

I've put a battery charger in the Met Shed behind trailer.  The batteries are on the floor by the power panel and charger is on the desk.  There is currently six spare, charged batteries.

8:00 - 9:00am

Removed both batteries at site with new/charged ones.  Will be charging batteries in Met Shed behind trailer.

The Tsoil at Hiland jumped ~10C at about 8:00 this morning. We will investigate.
