: Sensor Install
- New sensor (barometer) installed.
- Note: Datalogger program is still MAWN1B. Even though
new sensor was added, measurements not being recorded.
: Troubleshooting and Repair Visit
- Soil Temp A (2" depth) out since:
Jul 11, 2001 (min temp)
Aug 01, 2001 (max temp)
- Cable for Soil Temp A was bad (shorting out). Cable was
replaced by Jeff Andresen around 2:40pm.
: Data Cleanup
- Marked all SoilA readings as missing from Nov 25,
2000 (03:00) through Jan 10, 2001 (16:00). This
was needed due to faulty cable (see above notes
from: 01/10/2001). Rebuild MAWN database tables.
: Troubleshooting and Repair Visit
- Soil Temp A (2" depth) out since Nov 25, 2000 (03:00).
Cable was split (suspect rodent). Cabled was spliced
back together by Jeff Andresen shortyl after 4:00pm.
: 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=1140.
Only Observation Times were modified, not times of
Maxs and Mins. Users will need to take that into
consideration when using this data.
: Data Updates
- Data capture from PC208 at Michigan State University
resumed around 6:10am
- Cleaned up data from accidentally pulled power lead
to the HMP45C that occurred shortly after 2:00pm on
Sunday (08/27/2000) afternoon. Changed the following
entries:
5,2000,240,1410: Marked ATMP and RELH as missing (-6999)
5,2000,240,1415: Marked ATMP and RELH as missing (-6999)
60,2000,240,1500: Marked ATMP and RELH as missing (-6999)
24,2000,240,2400: Marked ATMP_MIN, ATMP_MINT, RELH_MIN,
and RELH_MINT as all missing (-6999)
: Phone line repaired
- Phone line was apparently repaired at sometime during
the day by the phone company.
: Troubleshoot check
- Phone Line to station did not sound right. Faint
tone with static or clicking sounds in the background.

Good chance that modem pulled from station (SN: 3947)
still in working order.
- HMP45C accidentally disconnected for approx five
minutes (around 2:20pm)
: Replaced Faulty Modem.
- Replaced modem (SN: 3943) with new modem (SN: 3947)
- Station Back On-Line after being down since 08/14.
- No Data was lost.
: Soil Temperature Sensors - moved to SW corner of tripod
Soil A: 2-inches under sod, west of south leg, N of Soil B
Soil B: 4-inches under sod, west of south leg, S of Soil A
: Fixed old data to reflect recent change in "mawn1b"
program - padded missing values to 5-minute data.
: Updated "mawn1b" to include Wind Speed, Air Temp,
and Relative Humidity in 5-minute data.
: Phone Line To Station Activated.
Clarksville station added to MAWN database
