Beginning in 2000 a Freewave FGR series 900 MHz radio network was incrementally installed for automated data retrieval. In 2015, iridium and cellular telemetry was installed at various stations. Data is also collected locally/manually during stations visits, which occur several times annually generally during the April to September period. ==================================================== == Derived Parameters and Mathematical Operations == ==================================================== Eppley PIR Longwave Radiometers had a lead-mercury installed annually to temperature correct the longwave radiation signal. In 2007 the Upper Kuparuk (UK) 10m Met site, Franklin Bluffs (FB) 10m site and Imnavait (IB) 10m site were rewired and reprogrammed to use the thermistor in the PIR rather than the battery. For most years Eppley PIR and PSP calibration constants to convert sensor signal from milliVolt output to radiation (W/m^2) was done on the logger during program run-time. Net Radiation is logged in milliVolts and sensor calibration values as well as wind speed correction are applied during QA/QC in Fairbanks. Soil Temperatures are logged with units of both resistance in kilo-Ohms and temperature in degrees C. On the logger the milli-Volt signal of the sensors are converted to resistance. Snow signal is recorded as distance in centimeters to ground / snow surface. Sensor distance to ground is recalculated every fall. ===================== == Parameter units == ===================== Radiation: Watts per meter squared Temperature: Degrees Celsius Relative Humidity: Percent Precipitation: millimeters of water Snow Depth: centimeters of snow Wind Speed: meters per second Wind Direction: degrees Soil Moisture: Percent Stage: feet Discharge: cubic meters per second ================== == DATA REMARKS == ================== For more details see Youcha, E.K., Gieck, R.E., Arp, C.D., Stuefer, S., and K. Irving, (2015).

Generally the quality of the data is thought to be very good. During the late fall, winter and early spring air temperature, relative humidity, wind speed and wind direction sensors can all experience rime ice or freezing precipitation. When this occurs the data collected by these sensors may be adversely affected. Sensor outages occur periodically due to animal damage and equipment failure. Position information recorded in the field using a GPS (WGS84). Elevation information estimated from topographic maps (NAD27 or NAD83).
