TRACER-CAT-LANL Aerosol Optics and Chemical Speciation - APS

Overview:

Aerosol size distribution, optical properties, and speciation data collected in La Port TX, during TRACER-CAT-LANL, July 2022, with basic trace gas measurements. All sampling was conducted with an identical aerosol inlet as the standard ARM-AOS systems.

The TRacking Aerosol Convection interactions ExpeRiment Carbonaceous Aerosols Thrust by Los Alamos National Laboratory (TRACER-CAT-LANL, July 2022) was designed to complement the larger ARM TRACER science goals to understand convective cloud lifecycles and aerosol-convection interactions. TRACER-CAT-LANL is focused on understanding the relationship between particle composition and light absorption and the influence of water uptake on this relationship.

This aerosol and trace gas data can be used to understand the relationship between particle composition and light absorption and the influence of water uptake on this relationship.

 

Instruments Include:

Picarro GHG

Photoacoustic Soot Spectrometer (PASS-3)

Humidified-cavity attenuated phase shift-single scattering albedo particulate matter monitor (H-CAPS-PMSSA)

Soot Particle Aerosol Mass Spectrometer (SPAMS)

Single-Particle Soot Photometer (SP2)

Cloud Condensation Nuclei Counter (CCNc)

Aerodynamic Particle Sizer (APS)

Scanning Mobility Particle Sizer (SMPS)

Abstract:

Aerosol size distribution, optical properties, and speciation data collected in La Port TX, during TRACER-CAT-LANL, July 2022, with basic trace gas measurements. All sampling was conducted with an identical aerosol inlet as the standard ARM-AOS systems.

The TRacking Aerosol Convection interactions ExpeRiment Carbonaceous Aerosols Thrust by Los Alamos National Laboratory (TRACER-CAT-LANL, July 2022) was designed to complement the larger ARM TRACER science goals to understand convective cloud lifecycles and aerosol-convection interactions. TRACER-CAT-LANL is focused on understanding the relationship between particle composition and light absorption and the influence of water uptake on this relationship.

This aerosol and trace gas data can be used to understand the relationship between particle composition and light absorption and the influence of water uptake on this relationship.

Instrument(s):Aerodynamic Particle Sizer
Data Type:TRACER-CAT-LANL (Carbonaceous Aerosol Thrust)
Scientific Measurements(s):
Measurement nameVariables
Particle size distribution, bounded by lower_size_limit and upper_size_limit
Data Quality:
Attribute Accuracy: Contact the instrument leads for more information on the field calibrations, if you have questions.
Positional Accuracy: Instrument calibrations were performed in the field.
Consistency and Completeness Report: Data set is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details.
Factor Affecting the Research: During the campaign, the instruments were operated in high humidity conditions. We operated nafion driers on the aerosol and gas inlet, which reduced the sample line humidity to 50% to 75% depending on the instruments internal temperature. Gaps (nan values) in the data are due to power outages, instrument maintenance, and instrument failure.
Use Restrictions: No use constraints are associated with this data.
