Abstract

The cavity attenuated phase shift extinction monitor is an optical extinction spectrometer that measures aerosols, broadband scatterers and absorbers of light that interact with solar radiation and influence the Earth’s radiation balance. The CAPS PMex uses a visible-light-emitting diode (LED), a sampling cell incorporating two high-reflectivity mirrors centered at the wavelength of the LED, and a vacuum photodiode detector.

High-spectral-resolution lidar (HSRL) systems collect data about clouds and aerosols. These systems provide vertical profiles of optical depth, backscatter cross-section, depolarization, and backscatter phase function. All HSRL measurements are absolutely calibrated by reference to molecular scattering, which is measured at each point in the lidar profile. Like the Raman lidar, but unlike simple backscatter lidars such as the micropulse lidar, the HSRL can measure backscatter cross-sections and optical depths without prior assumptions about the scattering properties of the atmosphere. The depolarization observations also allow robust discrimination between ice and water clouds. In addition, rigorous error estimates can be computed formore »« less

The aethalometer provides a real-time readout of the concentration of “black” or “elemental” carbon aerosol particles (BC or E) in an air stream. It measures the rate of change of optical transmission through a spot on a filter where aerosol is continuously collected and calculates the concentration of optically absorbing material in the sample. With a built-in reference check of the optical source and a mass flowmeter to monitor air flow rate, the aethalometer calculates the mean BC content of the sampled air stream and provides on-the-spot readout.

The ultra-high-sensitivity aerosol spectrometer (UHSAS) is an optical-scattering, laser-based, aerosol particle spectrometer system for sizing particles in the 60 to 1000 nanometer (nm) range [1–3]. The instrument counts particles in up to 100 user-specified sizing bins. The instrument’s laser illuminates particles, which scatter light. The system captures the peak light signals that are generated. These signals are used for particle sizing, since the amount of light scattered correlates strongly with particle size. The UHSAS is part of the aerosol observing system (AOS).

As of 5 August, 2015, Los Gatos Research (LGR) CO/H2O/N2O analyzer instruments (COANALYZERs) were deployed in the Atmospheric Radiation Measurement (ARM) Aerial Facility (AAF), the third ARM Mobile Facility (AMF3) Aerosol Observing System (AOS), Eastern North Atlantic (ENA) AOS, and Mobile AOS (MAOS-C). The N2O/CO analyzer uses LGR’s patented Off-axis ICOS technology, which employs a high-finesse optical cavity as the measurement cell. LGR’s technology has many proven advantages over conventional first-generation cavity ringdown spectroscopy (CRDS) techniques. In brief, since the laser beam does not have to be resonantly coupled to the measurement cell, precise beam alignment is not critical. Mentorsmore »« less

The sulfur dioxide analyzer measures sulfur dioxide based on absorbance of ultraviolet (UV) light at one wavelength by SO2 molecules that then decay to a lower energy state by emitting UV light at a longer wavelength.
