Westminster Weather Station Maintenance Log
Back to Westminster Weather
October 06, 2012
Weather station is functioning normally. Past year of operation has been relatively trouble free. Only difficulties encountered has been keeping birds off the edge of the rain bucket.
October 28, 2011
Westminster weather station has suffered numerous problems over the last 12 months which are, hopefully, all resolved. Primary problem has been with computers. Am now on the third used computer. It seems to be functioning well. Uploads to all three servers are now functioning: weather.wsa.net, wunderground.com and cwop.aprs.net.
The weather station itself has not had any problems. The sensors are all functioning normally and reliably. The Vantage Pro 2 equipment is outstanding!

The hosting server has recently been changed. So, the uploading configurations to the Westminster Weather Station have been updated accordingly. Meanwhile, glitches with CWOP site have regularly caused the software, WeatherLink, on our home station computer to freeze up. So, I have had to stopped uploads to CWOP until something is figured out about that site. With CWOP uploads stopped, WeatherLink has been operating without a problem.

The anemometer has been working without problems since it was repaired in May. Since then software problems have plagued the station. Am running WeatherLink on a Windows XP machine. WeatherLink locks up at least once a week and usually on the weekend when I am not around to restart the system. So the Westminster weather station has been less reliable on the data uploads the last month or so. Am talking with tech help to try and resolve the problem.

Have been having regular problems connecting to the Internet which have crippled data uploads every two or three days. Troubleshooting the system hasn't been able to pinpoint the problem, not even whether it is the PC or the network. Perhaps the problem is a combination of both. The situation continues to be monitored and the weather server restarted as needed. Apologies for the unreliable nature of the WSA weather station these last few weeks.

Finally able to work on the broken anemometer. Tech support from Davis Instruments has been very helpful. Apparently the reed switch in the hub of the anemometer was sticking. So the instrument was not recording wind speed but the wind direction function continued to work properly. Poking around in the hub of the anemometer with a screwdriver must have loosened the switch. The anemometer is now fully functional again. The station's anemometer was down for over seven and half months! Hopefully the fix will last. If it goes down again, I will replace it with a refurbished unit.

Rain gauge was clogged and didn't record the rainfall earlier this week. Missed about .7 inches of rainfall. Cleaned out the gauge today. Ready for the next rainfall.
March 16, 2010
Replaced main ISS battery which keeps the unit in operation overnight when the solar cell isn't functioning. Data was not collected overnight since March 13th, 11 PM when the battery depleted too much to keep the sensors functioning.
Wind speed is still not functioning. Repairs are due soon.
Jan. 13, 2010
Replaced the anenometer transmitter circuit board. Transmitter is now transmitting correctly, but only the directional vane is registering data. The wind cups for wind speed are not working properly. Will have to access the anenometer mast to try and repair that. This is not a simple process as the mast is high up above the peak of the school's gymnasium. Hopefully the repairs can be made before too long.
Dec. 2, 2009
Rain gauge was not registering any rain today even though there has been .84 inches of rain nearby at Daniel Field. A quick check on the equipment revealed that a couple of oak leaves were blocking the orifice. I cleared these and rainfall is now being recorded. Unfortunately, the gauge missed a significant amount of rainfall today.
A student observed that for the last couple of weeks the wind speed has not registered higher than 2 mph. Clearly something is wrong with the anemometer. Checking the historical data shows that the anemometer quit working on October 9th. A call to the manufacturer to explain the problem has them puzzled as to what could be wrong. Davis Instruments is going to send out a testing cable to see where the problem might be - electronics or the anemometer itself.
October 1, 2009
Haven't been keeping the maintenance log current. But have been running regular checks on the weather station equipment. Replaced battery in both the ISS and anemometer transmitter. Battery in the anemometer depleted rather quickly. Put a new one in today. If it depletes over a couple of weeks then there must be something wrong with the circuit board.
Station is running well otherwise.
November 21, 2008
Battery on the senor suite died. An examination of the data records indicates that the battery has been without charge since 11:30 PM November 16th. The solar cells provided power during the daylight hours from about 8 AM to 6 PM. However, without the battery, no data was collected during the night. The battery is not replaced and should be good for another six months.
Clean the raing guage. All systems are operational.
November 5, 2008
Web server problems have prevented updating of the local weather conditions since Oct. 24, 2008. Those problems have now been resolved and WSA weather stationis back online and updating every 15 minutes.
Note: Heat Index and Wind Chill graphics have been added to the front page. Additional weather details continue to be available via the links to the left.
October 23, 2008
Checked the ISS to confirm proper functioning. No problems. Rain guage cleaned.
September 23, 2008
Weather equipment verified. All system are functional as appropriate.
August 25, 2008
Rain gauge and ISS (Integrated Sensor Suite) checked. Gauge is clean; ISS functioning normally.
May 21, 2008
Put a new battery in the Vantage Pro 2 Integrated Sensor Suite (ISS). Lost overnight data collection for a week to ten days because the battery went dead. With the solar panel functioning during daylight hours, daytime data collection continued uninterrupted. Rain Gauge checked and cleaned.
April 28, 2008
Cleaned the rain gauge, removing dirt and accumulations of debris which hindered accurate recording of rainfall rate.
March 10, 2008
Am working on getting a correct calibration for the barometric readings. CWOP analysis indicates the barometric readings are consistently low. I recalibrated today. Will check the data consistency in a few days.
Recalibration of the dew point readings seems to have had the desired affect of readings more consistent with the other areas stations.
February 14, 2008
The replacement part for the vandalized cover of the circuit board box arrived and is now installed. Weather station is back to normal.
February 6, 2008
Damage to the instrument weather proof box needs to be repaired; the breakage, fortunately, hasn't affected the station's performance but does make it station vulnerable to corrosion.
Calibrated the relative humidity 5% lower; also made adjustments to the barometric pressure to obtain more accurate readings.
January 25, 2008
Station equipment examined. All sensors are functioning as needed.
July 24, 2007
Anemometer functions are now operational and data being uploaded to the various servers. Equipment was set up about 10:45 AM.
July 18, 2007
Weather station down today from about 9:30 to 11:30. Checked the equipment to be sure all is in good order. Re-sited the rain/temperature/humidity suite of instruments in order to obtain more accurate data; and the equipment will be more easily checked for routine maitenance.
Anemometer is down until a new transmitter arrives and is installed.
May 1, 2007
Weather Underground sent and alert indicating that the station tends to show unusually high outside temperatures relative to area stations. The instrumentation needs to be re-located in order to record conditions that are more representative of the area. Have set uploads of new data to 10 minute intervals on the home page and 30 minute intervals to Weather Underground.
March 5, 2007
Data updates adjusted to twice an hour. Rapid Fire feature disabled. Station software updated to accommodate the new Daylight Savings Time parameters.
