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 105’ with 6 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 Double Fence Intercomparison Reference (DFIR) near the tower, and a series of throughfalls located in the soil array.
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:
Field ecologists collect the following types of observational data at this site:
