- Replaced both leaf wetness sensors
- Loaded Logger Program - ABCF (hourly collection cycle)
- Added "hourly battery voltage" to hourly database table
- Loaded MAWN Program - ABCW (03-hour collection cycle)
- Station converted to Wireless Broadband communications
- Communications cable was accidentally cut during local
trenching work. Field staff was able to splice cable
back together before any data was lost.
- General station maintenance and system checks, including:
- Tipping-bucket rain gauge test (faulty pcpn data
that was introduced was removed on 06/11/09)
- Anemometer was replaced (noisy bearings)
- It appears that Leaf Wetness 0 (Standard Mount) has been
a bit unreliable as several instances of "missing" have
recently appreared in the 5-minute leaf wetness data.
To correct this problem, the stanard leaf-wetness
sensor was replaced this morning (10:15am)
- Faulty precipitation data that was introduced on
July 31 (day=212) was removed from archived raw
data file. Entries in MAWN database were also
corrected.
- Sensor Calibration/Testing:
- Manual test of precipitation bucket.
- Testing led to introduction of fauly PCPN data
at 825 (five-minute), 900 (hourly) and 2400 (daily).
- Sensor replacement:
- Soil Moisture A and Soil Moisture B both replaced (CS616)
- Datalogger progam "mawn1c" loaded and compiled.
- General station maintenance and system checks.
- Work was done approx: 14:00 - 15:00 (Day=192)
- General station maintenance and system checks.
- Work was done approx: 13:40 - 14:20 (Day=129)
- Recent data loss due to existing battery being sensitive
to cold weather which would cause the battery to periodically
fail.
- New battery was installed this morning.
- Funnel to the tipping bucket on the rain gauge was
plugged. Debris was removed and obstruction was
cleared this afternoon (09/30/05 - Day=273)
- General Station Maintenance and System Checks:
- weed removal and application of Round-Up above soil temps
- cleaned/checked all sensors
- cleaned/serviced precipitation bucket
- approximate time of service: 1:15pm
- Datalogger Failure on Day=67 (03/08/2005). Datalogger
Program MAWN1B reloaded at 14:30 on Day=73 (03/14/2005).
Data collection once again operational.
- Due to Datalogger outage, data for the following time
period is not available:
Day=67 (03/08/2005): 04:15 - Day=73 (03/14/2005): 14:25
- Replaced Temperature/Relative Humidity Sensor (HMP45C).
- General Station Maintenance and System Checks:
- weed removal and application of Round-Up above soil temps
- Work was done approx: 14:05 - 14:20 (Day=238)
- Replaced Tipping Bucket Rain Gauge.
- Leaf Wetness B (canopy) sensor installed. The sensor
was placed in a shrub planted near the foot of the NE
leg of the station.
- Daylight Savings Time Started on Day=97, Time=200.
- Time of Obs were modified by one hour (forward)
from Day=97, Time=200 through Day=98, Time=1225.
- Installed Pressure sensor. However, no changed made
to datalogger program so pressure is currently not
being recorded.
- Relocated Leaf Wetness A:
Bracket mounted 40-inches from center of tripod,
39-inches (~1m) high. Mounted on NE leg, sensor
facing north.
- 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=303, Time=900.
- Reburied Soil Temperatures - installed in SW
quadrant of station:
Soil A: 2-inches under sod, W of S leg, N of Soil B
Soil B: 4-inches under sod, W of S leg, S of Soil A
- Buried Soil Temperature Probe (Horizontal Placement)
is SE quadrant of station:
Soil Moisture A: 10" depth, E of S leg, facing south
- Moved Pyranometer Stand to face SW (originally was
oriented to the SE).
- Needs:
Leaf Wetness A needs to be moved to standard mount
on NE leg.
Additional LeaF Wetness (Sensor B)
Additional Soil Moisture (Sensor B)
NOTE: Current Soil Moisture needs to be switched
in the datalogger. Sensor A should be buried
at 4" and Sensor B should be placed at 10".
- Daylight Savings Time Started on Day=91, Time=200.
- Time of Obs were modified by one hour (added) from
Day=91, Time=200 through Day=91, Time=1500.
Observation Times, including times of max/mins
were modified.
- 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=303, Time=1500.
Only Observation Times were modified, not times of
Maxs and Mins. Users will need to take that into
consideration when using this data.
- Uploaded Program: mawn1b (10:26am)
- Test Tipping Bucket (10:50am)
- Moved Soil Temps from SE corner to SW:
Soil A: 2-inches under sod, W of S leg, N of Soil B
Soil B: 4-inches under sod, W of S leg, S of Soil A
- Notes:
Soil Moisture A = E of S leg is bent.
Need two new soil moisture probes, additional leaf
wetness sensor, and need to move Pyranometer to face
to the SW.
Leaf Wetness A is mounted at the end of NW leg at
a height of 20.5". May need to moved to standard
install off of NE leg (40" from center of tripod,
39" high).
