high humidity have been too high. Sensor was replaced to
correct this problem.
- Polyhouse Sensors replaced.
- Station Move.... moved about 550-feet.
- Replaced Modem
- Faulty polyhouse soil temperature (Pot B) that was
reported during the following time period has been
marked as "missing":
04/04/10 (d=94) 00:05 - 08/31/10 (d=243) 24:00

- General station maintenance and system checks, including:
- Soil Moisture sensors now installed vertically:
- MSTR 0: profile of depth = 0 - 12"
- MSTR 1: profile of depth = 12 - 24"
- Work was done approx: 12:30 - 1330 (Day=141)
- Station Maintenance last week (11/21/07) led to some
faulty data being introduced. Removed all faulty
data. The loss of power also introduced a gap in
the dataset.
- Loaded MAWN Program, 1WO (hourly power cycle) [10:35]
- Replaced battery [15:40]
- Recent telecommunication problems (faulty cell-modem)
have been corrected. Cell modem was replaced at
11:00am this morning (d=276).
- Data from CR23X datalogger that was pulled from the field
was recovered. Data for the following time period was
reloaded into the MAWN database:
May 30. 2007 [22:05] - June 06, 2007 [12:45]
Small gaps of missing data still exist due to periods of
system work and hardware replacement.
- Telecommunications Troubleshooting:
- Recent connection troubles continue which led to
the replacement of the CR23X datalogger this afternoon.
- As of 5:00pm, communications back online
- Work performed: 3:45pm - 5:15pm
- Recent telecommunication trouble:
- Faulty serial cable may have been the cause of
recent telecommunication problems. Cable was
replaced this morning at 11:00am.

- Broadband cell-ip modem installed
- Datalogger progam "mawn1wo" loaded and compiled.

- Work was done approx: 14:00 - 15:00 (Day=136)
- Faulty Phone Line Was Repaired By SBC
- Modem was showing signs of inconsistent behavior, so that was
also replaced.
- Battery had failed and was also replaced. Due to the battery
failure, data for the following time period was lost:
Day=329 (11/25/05) 18:15 - Day=334 (11/30/2004) 10:35

It was determined that the Temp/RH sensor at the West Olive
station has slowly drifted toward higher readings. The drift
can be traced back to August 2004. Air Temperature and
Relative Humidity readings between August 2004 - April 13, 2005
are not completely accurate and eventually may be removed from
the MAWN database.

- Time of Obs were modified by one hour (forward)
from Day=97, Time=200 through Day=97, Time=415.
- Replaced CR10X with CR23 datalogger. This move allows
extra inputs for additional sensors needed at this site.
- Moved and Reburied Soil Temperatures. Also installed a
fourth sensor - installed in SW quadrant of station:
Soil A: 2-inches under bare soil, W of S leg
Soil B: 4-inches under bare soil, W of S leg
Soil C: 12-inches under bare soil, W of S leg
Soil D: 16-inches under bars soil, W of S leg
- Installed temperature sensors in polyhouse (cables buried
from bottom of south leg diagonally to southwest polyhouse:
PTEMP A: Polyhouse Air Temperature (sensor 1)
PSOIL A: Polyhouse Soil Temp-A (juniper) (sensor 2)
PSOIL B: Polyhouse Soil Temp-B (yaxus [yew]) (sensor 3)
- Daylight Savings Time Ended on Day=301, Time=200.
- Time of Obs were modified by one hour (subtracted)
from Day=301, Time=200 through Day=301, Time=605.
- Add missing fields to old data to reflect changes made by
the installation of new datalogger program. Added the
following to entries prior to Day=150, Obs Time=1700:
Data Code: 60, field #: 18, value = 6999
Data Code: 24, field #: 35, value = 6999
Data Code: 24, field #: 36, value = 6999
Data Code: 24, field #: 37, value = 6999
Data Code: 24, field #: 38, value = 6999
- Clean-Up Faulty Data. Leaf Wetness Sensors were tested
at 1:40pm on May 30 (Day=150). Marked the following as
"dry" (value=6999):
Five Minute Data:
Day=150, Time=1340, Field 5 (value=6999)
Day=150, Time=1340, Field 6 (value=6999)
Hourly Data:
Day=150, Time=1400, Field 16 (value=0)
Day=150, Time=1400, Field 17 (value=0)
- NOTE: Since new program was loaded at approximately 4:15pm
on 05/30/2001, Daily totals and Max/Min values that
are calculated by the datalogger were reset to the
time the new program was loaded.
- Moved and Reburied Soil Temperatures. Also installed a
third sensor - installed in SW quadrant of station:
Soil A: 2-inches under bare soil, W of S leg, N of Soil B
Soil B: 4-inches under bare soil, W of S leg, S of Soil A

Leaf B: Selected Canopy: Shrubs end of NE leg. 14" high
- Loaded New Datalogger Program: mawn1wo
Program: mawn1wo
Time (approx): 4:15pm, Day 150 (5/30/2001)
- Needs:
Data Cleanup: Adding third soil temperature probe
required the loading of a modified
version of "mawn1b".
The new program is called "mawn1wo"
and the following new fields were added:
Hourly: Soil Temp C
Daily: Max Soil Temp C,
Time of Max Soil Temp C,
Min Soil Temp C,
Time of Min Soil Temp C
MAWN database table for West Olive will
need be modified and rebuild. Also,
"decoder" which produces pre-generated
reports will need to be modified.
Reinstalling soil temperature and soil
moisture probes and adding/testing leaf
wetness grida most likely introduced
faulty data - rawdata will need to be
corrected.
- Updating Program to MAWN1B on 01/29/2001 reset all max/min
and totalling buffers on datalogger. Needed to repair some
of the daily data entries for 01/29 (24,2001,29,2400,....):
Field #: Replacement Value:
06: ATMP_MIN -5.97 (based on hourly values)
07: ATMP_MINT 100 (based on hourly values)
08: RELH_MAX *** no change made ***
