Atmospheric and soil measurements made at the ABLE
include winds, air temperatures, water vapor, radiation, precipitation, vegetation state,
surface temperature, soil temperature, and soil moisture.
There are 5 permanent instrumented sites: Beaumont (BE), ABLE Project Office (CS or APO),
Oxford (OX), Smileyberg (SM), and Whitewater (WH). A temporary site is located at
Brainerd (BR) and rain gauges are installed in numerous locations.
Instrumentation installed at the ABLE includes:
- Three 915 MHz RWP-RASSes (Radar Wind Profiler - Radio Acoustic Sounding System)
to measure wind speed, wind direction, and virtual temperature profiles.
- Three Minisodars (mini - sound detection and ranging) to measure wind and turbulence profiles
between the heights of 10 m and 200 m.
- One Energy Balance Bowen Ratio (EBBR) flux station (surface sensible heat and latent
- Two Eddy-correlation (ECOR) flux systems (surface sensible heat, latent heat, carbon
dioxide fluxes); one permanent and one portable.
- Five Automated Weather Stations (AWS).
- Two soil moisture and temperature (SM/ST) profile systems.
- Two Radiometer Suites (PAR, net radiation, albedo, shortwave solar, MSR/LAI).
- Three Infrared Temperature (IRT) sensors (included in Radiometry / Vegetation State link below).
- Forty recording rain gauges at locations in the Towanda sub-basin.
- One data hub/central location for data collection at the Central Site.
- One Radiosonde System at the Central Site.
- One (extra) instrument pad for visiting scientist instrument accomodation.
