SD-201 Wind Direction o from N 10/02/2001 - B5465
B5466
W4384
0.072 o/mV
The mean wind direction vector at 113, 52, and 3 meters. The standard deviation of the wind directions are also recorded.
SS-201 Wind Speed m/s 10/02/2001 - B6417
W4374
W4371
0.0440 m/s/pulse+0.2946 m/s
0.0441 m/s/pulse+0.3314 m/s
0.0439 m/s/pulse+0.3090 m/s
The mean wind speed at 113, 52, and 3 meters. The peak 5-min gust and standard deviations are also recorded.
RTD Temperature oC 10/02/2001 - - 0.02 oC/mV-50 oC
The Temperature Sensor is mounted at 3, 52, and 83 meters.
RTD Delta Temperature oC 10/02/2001 - - 0.0022 oC/mV-4.444 oC
The Delta Temperatures are measured by two sensors (different from temperature sensors above):
    ΔT83m= T83m- T52m and ΔT113m= T113m- T83m
RTD Dewpoint Temperature oC 10/02/2001 - - 0.02 oC/mV-50 oC
The Temperature Sensor is mounted at 3, 52, 83, and 113 meters.
? Pressure mBar 10/02/2001 - - 0.052 mBar/mV+740 mBar
The Pressure Transmitter is mounted in the building at 3 meters.
- CR23X Battery Voltage V 10/02/2001 - - -
CR21X internal battery voltage.
- CR23X Temperature oC 10/02/2001 - - -
CR23X internal temperature.
CSI Building Temperature oF 10/02/2001 - 107 1.8 oF/mV+32 oF
The Temperature Sensor is mounted in the building.
- UPS Status mV 10/02/2001 - - -
UPS Status signal; 900 - 1000 mV = Utility Power & UPS Okay; >1000 mV indicates a utility power problem and UPS batteries may be providing power; <900 mV indicates a utility power problem and UPS batteries are NOT providing power.
- Security mV 10/02/2001 - - -
Building door security closure switch; 1000 mV +/- 20 = Door Closed.
Notes:
  • Data Sample rate is 1/sec, with 5-min averages.
  • Raw data files were downloaded directly from Campbell Scientific CR23X datalogger using LoggerNet.
