- Time of Obs were modified by one hour (subtracted)
from Day=301, Time=200 through Day=348, Time=830.
: Phone Line Troubles
- Phone switch has died once again. Decided to bypass
switch with use of separate, dedicated phone line for
weather station. New phone line will be ordered.
: Data Cleanup
- Wind Vane was found off the wind sentry mount. Looking at
the data, it appears that the wind vane was off since Fri.
August 24, 2001 - 4:00am. Instrument was reinstalled by
Jim Breinling on Tue. August 28, 2001 - 11:05am.
The following modifications to the raw datafile were made
to cleanup the faulty data:
Hourly Data: Marked as missing (-6999) the following:
08/24/01 (day=236), time=0400
thru
08/28/01 (day=240). time=1100
: Data Repair
- Due to plugged rain gauge, recent precipitation
values were reported incorrectly. The following
modifications were made to the raw data file for
Fremont:
Five Minute Data: Marked as missing the following:
05/14/01 (day=134), time=1235
thru
04/17/01 (day=137), time=1340
Hourly Data: Marked as missing the following:
05/14/01 (day=134), time=1300
thru
04/17/01 (day=137), time=1400
Daily Data: Adjusted 0.54" (13.72mm) reported
incorrectly on 05/17/2001 as follows:
Daily Totals Changed:
05/15/01 (135) = 47.24mm (+10.41mm)
05/16/01 (136) = 9.65mm (+ 3.30mm)
05/17/01 (137) = 0.00mm (-13.72mm)
: Precipitation Gauge Maintenance
- Funnel of Tipping Bucket Rain Gauge Was Clogged. Jim
Breinling of MSU Extension cleared the problem at 1:40pm.
- Precipitation values from recent rain events are
inaccurate and will need to be modified (see below)
: Daylight Savings Time Adjustment.
- Daylight Savings Time Ended on Day=303, Time=200.
- Time of Obs were modified by one hour (subtracted)
from Day=303, Time=200 through Day=304, Time=1930.
Only Observation Times were modified, not times of
Maxs and Mins. Users will need to take that into
consideration when using this data.
: Wind Sentry Rotated 180-degrees to correct data that was
being reported. Now Wind Sentry is installed opposite of
normal with anemomter facing north and wind vane facing
south.
Inspection of faulty phone line/modem. Determined that
COMM SWITCH has failed. Connecting a direct phone line
(bypassing switch) to the datalogger allows modem to pick
up. Switch left at site until replacement or dedicated
phoneline is installed.
Field Technician: Tom Cate
: Additional Installation.
- Leaf Wetness B: Bracket mounted on wooden stake outside of
wire tomato cage, off of NE tripod leg.
Installed 12" off ground, immediately
north of tomato plant. Sensor facing
NE, eventually will be covered entirely
by tomato plant.
: Fremont station added to MAWN database
: Phone Line To Station Activated.
- Buffer in Data Logger Rolled-over causing loss of initial data.
NOTE: To access via outside modem (e.g. PC208), need to
append the following string to phone number:
,,,#22,#22
: Additional Installation.
- Solar Panel: Mounted just below Wind Speed and Wind
Direction Instruments (just below coupling
near the top of the tripod).
- Notes: Appears RoundUp was applied in SW corner (above
soil temps) and NE corner (future tomato plot).
Telephone Switch (CS7500) dropped off in main
office.
Rodent appears to have dug a hole in the
vicinity of the soil temperature sensors.
- Needs: Enclosure Bracket, Phone Switch and Phone
Line Installation.

of Soil Temp B (straight in from fence post).
- Soil Temp B: 4-inch under sod, west of south leg, south of
Soil Temp A (straight in from fence post).
- Soil Moisture A: East of south leg, approx. one foot north
of Soil Moisture B (straight in from post).
- Soil Moisture B: East of South leg, approx. one foot south
of Soil Moisture A (straight in from post).
