Construction Status for this Site
Located three hundred miles north of the Arctic Circle, the Barrow field site landscape is representative of the polygon tundra and lake systems across the northern extent of the North Slope of Alaska. Barrow spans 50 square kilometers and includes a 26’ tall meteorological flux tower and nearby soil sensors. NEON scientists also collect field observations throughout the field site.
Total data products planned for this site: 109
Site Host & Access Site Host:
Barrow Environmental Observatory
Is additional non-NEON research allowed at this site?:
Yes, non-NEON research activities are allowed in this area. Researchers must obtain their own permits with the site host(s).

Data Collection Types
Airborne Remote Sensing Surveys
Remote sensing surveys of this field site collect lidar, spectrometer and high-resolution RGB camera data.
The flux/meteorological tower at this site is 26’ with four measurement levels. The tower top extends above the vegetation canopy to allow sensors mounted at the top and along the tower to capture the full profile of atmospheric conditions from the top of the vegetation canopy to the ground. The tower collects physical and chemical properties of atmosphere-related processes, such as humidity, wind, and net ecosystem gas exchange. Precipitation data are collected by a tipping bucket at the top of the tower.
This site has one phenocam on the top of the flux tower and one near the bottom of the tower.
Soil Sensor Measurements
This site has five soil plots placed in an array within the airshed of the flux tower. The following measurements may be collected at the soil surface in each soil plot:
Photosynthetically Active Radiation (PAR) at soil surface
Soil heat flux
The following measurements are collected at multiple depths in each soil plot:
