The Campaign
The WB-57 Aerosol Mission (WAM) was a NASA field campaign that analyzed the chemical composition of aerosols in the upper atmosphere. WAM had a single deployment based at Ellington Field in Houston, Texas, during spring 1998. The NASA WB-57 aircraft was equipped with multiple in situ sensors, including the Particle Analysis by Laser Mass Spectrometer (PALMS), the Multiple-Angle Aerosol Spectrometer Probe (MASP), and the JPL Laser Hygrometer (JPL), to collect data on aerosol properties and meteorological parameters. Radiosonde measurements were also collected during the campaign.

The Particle Analysis by Laser Mass Spectrometry (PALMS) is a laser ionization mass spectrometer operated by NOAA. PALMS provides in situ measurements of aerosol particles and their chemical composition by using a UV laser pulse (193 nm) to generate ions. These ions are then analyzed with a time-of-flight mass spectrometer to produce the mass spectrum of each particle, which can be used to classify individual aerosol particles. PALMS has an aerosol size range of 0.2 to 3 microns and typically collects data at about 1 to 10 Hz. It can be used for either airborne or laboratory aerosol measurements.

Generic-Atmospheric State (Gen-AtmsState) refers to non-specific instruments on a platform used for measurements of atmospheric state parameters. These are typically in situ sensors that measure temperature, pressure, humidity, and wind speed/direction. Types of atmospheric state instruments include thermometers, hygrometers, barometers, and anemometers.

The NOAA CH4 is an in situ airborne near-infrared tunable diode laser (TDL) absorption spectrometer. The laser is tuned to the methane (CH4) absorption line at 1.653 μm and measures the intensity of the transmitted radiation. The CH4 concentration is then determined using the Beer-Lambert law. NOAA CH4 scans continuously over the CH4 absorption at a rate of 0.25 to 0.5 kHz and has a typical integration time of 2 seconds.

The Condensation Nuclei Counter (CNC) is an in situ optical sensor produced by Droplet Measurement Technologies. It detects cloud condensation nuclei (CCN) by supersaturating the sampled air, allowing CCN particles to become detectable. The particles are then measured with an optical particle counter (OPC). CNC can detect particles from 0.75 to 10 μm in diameter and operates at a sampling rate of 1 Hz. It is suitable for both airborne and ground-based operations.

The Multiple Axis Resonance Fluorescence Chemical Conversion Detector for ClO and BrO (ClO/BrO) is an in situ airborne analyzer operated by Harvard University. It provides measurements of chlorine monoxide (ClO) and bromine monoxide (BrO) in the upper troposphere and lower stratosphere. ClO and BrO are converted to chlorine (Cl) and bromine (Br) through the addition of nitric oxide (NO) in the sample air. Cl and Br concentrations are detected through resonance scattering in the vacuum ultraviolet (119 nm) to determine ClO and BrO concentrations. ClO/BrO has a detection limit greater than 1 pptv.

The Nucleation-mode Aerosol Size Spectrometer (NMASS) is an airborne, in situ spectrometer used to measure particle size distribution and cloud condensation nuclei (CCN). NMASS includes five parallel condensation nucleus counters (CNCs) that sample particles within the 3 to 60 nm diameter range. It can be mounted on various types of aircraft and is ideal for sampling cirrus clouds in the upper atmosphere. NMASS delivers rapid measurements with a temporal resolution of 10 Hz.

Radiosondes are a balloon-borne instrument package used to collect profile measurements of pressure, temperature, humidity, and winds. These sensors are connected to a radio transmitter that sends the measurements to a ground receiver typically operating in the 400-406 MHz range. They typically provide measurements at 1-6 seconds, depending on the type and manufacturer of the radiosonde. Radiosondes are used for weather forecasting, ground truth satellite data, atmospheric research, and input for weather prediction models.
