EOL manages an NSF-owned ground-based, polarimetric weather radar that provide atmospheric researchers with measurements of the structure, movement and severity of precipitating cloud systems and on the type and amount of resulting precipitation. Additioanlly, EOL's surface, sounding, and profiling systems serve the advanced observational needs of the atmospheric science community by providing a flexible, state-of-the-art backbone measurement capability applicable to a wide range of experimental needs - emphasizing advanced sensor capabilities, sensor integration, system mobility, and the ability to deploy to remote or difficult locations.

Integrated Sounding System (ISS)

The ISS combines surface, sounding, and remote sensing instrumentation to provide a comprehensive description of lower atmospheric thermodynamics and winds. Integrated instruments are: 1) Radar Wind Profiler (with RASS for temperature profiling), 2) a GAUS radiosonde system, 3) an enhanced surface meteorological station (radiation and precipitation data in addition to standard temperature, pressure, humidity and wind), and 4) local data processing, display, and communications infrastructure. 915 MHz and 449 MHz wind profiler radars are available.

Integrated Surface Flux System (ISFS)

The ISFS can be deployed as a widely distributed network of surface weather stations - measuring the surface energy budget, fluxes, and some soil parameters. Alternatively, it can be deployed in closely spaced arrays to support intensive micrometeorological research at a single site. Solar power, RF modems and satellite data transmission permit ISFS to operate almost anywhere.

MicroPulse DIAL (MPD)

The MicroPulse Differential Absorption Lidar (DIAL) is a compact, field-deployable, micro-pulse differential absorption lidar that provides continuous monitoring of water vapor in the lower troposphere. 


S-band Dual-Polarization Dual-Wavelength Doppler Radar (S-Pol)

The S-band, dual Polarimetric (S-Pol) radar combines dual-polarization and Doppler measurements on a single radar platform.
