ARM Raman Lidar*

The Raman Lidar (RL) is an active, ground-based laser remote sensing instrument that measures vertical profiles of water-vapor mixing ratio and several cloud- and aerosol-related quantities. Lidar (light detection and ranging) is the optical analog of radar, using pulses of laser radiation to probe the atmosphere. This system is fully computer automated and will run unattended for many days following a brief (~5-minute) startup period.

ARM Atmospheric Emitted Radiance Interferometer (AERI)*

The AERI is a ground-based instrument that measures the downwelling infrared radiance from the Earth’s atmosphere. These upward-looking surface observations can be used to obtain vertical profiles of tropospheric temperature and water vapor, as well as measurements of trace gases (e.g., ozone, carbon monoxide, and methane) and downwelling infrared spectral signatures of clouds and aerosols.

ARM Balloon-borne Sounding System [Radiosonde] 

The balloon-borne sounding system provides in situ measurements (vertical profiles) of both the thermodynamic state of the atmosphere and the wind speed and direction. During some field campaigns, sonde operations from multiple stations around a central location with baseline measurements, like a mobile facility, can provide important constraints for model simulations.

ARM 915 MHz Wind Profiler*

The 915 MHZ WP is a long-wavelength Doppler radar which detects the backscattered signals from turbulence-induced refractive index variations. The profiler thus tracks the motion of the turbulent eddies which drift with the mean flow, providing a measurement of the mean wind velocity.

 

ARM Doppler Lidar*

The Doppler Lidar (DL) is an active remote sensing instrument that provides range- and time-resolved measurements of radial velocity and attenuated backscatter. The principle of operation is similar to radar in that pulses of energy are transmitted into the atmosphere; the energy scattered back to the transceiver is collected and measured as a time-resolved signal. From the time delay between each outgoing transmitted pulse and the backscattered signal, the distance to the scatterer is inferred.

ARM C-band Radar (C-SPAR)

The C-SAPR is a C-band dual-polarization Doppler weather radar manufactured by ARC, Inc. The C-SAPR operates in a simultaneous transmit and receive (STAR) mode, meaning that the transmit signal is split so that power is transmitted on both horizontal and vertical polarizations at the same time. The C-SAPR also has the ability to transmit on a single polarization (either horizontal or vertical) and measure linear depolarization ratio (LDR).

ARM Aerosol Observing System

The aerosol observing system (AOS) is the primary Atmospheric Radiation Measurement (ARM) platform for in situ aerosol measurements at the surface. The principal measurements are those of the aerosol absorption and scattering coefficients as a function of the particle size and radiation wavelength. Additional measurements include those of the particle number concentration, size distribution, hygroscopic growth, and inorganic chemical composition.

Ka-band Scanning ARM Cloud Radar (KASACR)

ARM's scanning cloud radars are fully coherent dual-frequency, dual-polarization Doppler radars mounted on a common scanning pedestal. Each pedestal includes a Ka-band radar (2kW peak power) and the deployment location determines whether the second radar is a W-band (1.7 kW peak power) or X-band (20 kW peak power).

NASA ALVICE Mobile Laboratory

The NASA/Goddard Space Flight Center ALVICE mobile laboratory includes a Raman lidar system, a GPS for total column water, radiosonde and frostpoint hygrometer launch capability and a ventilated surface reference station. For PECAN, Raman lidar and GPS measurements are the focus. The Raman lidar makes use of Raman scattering in the atmosphere to measure various atmospheric properties, in particular water vapor for PECAN. This permits the study and improved understanding of mesoscale dynamics, warm and cold clouds and aerosols.
