Flow-induced errors in airborne in situ measurements of aerosols and clouds

Abstract. Aerosols and clouds affect atmospheric radiative processes and climate in many complex ways and still pose the largest uncertainty in current estimates of the Earth’s changing energy budget. Airborne in situ sensors such as the Cloud, Aerosol, and Precipitation Spectrometer (CAPS) or other optical spectrometers and optical array probes provide detailed information about the ...

Drops in a Cloud: An SBIR-funded spectrometer is at the forefront of global climate research

Weeks before the athletes took to the ice and snow at the 2018 Winter Olympics in South Korea, Dr. Duncan Axisa was in the mountains around PyeongChang, studying ice-forming particles. Later in the ...

Impactor Inlet

The Impactor Inlet is an accessory for the Aerodynamic Particle Sizer® (APS™) spectrometer. It combines a single-stage impactor with a filter to take a size-segregated sample. It then directs a small, representative sample of the initial test aerosol (diluted at 80 to 1) into the APS spectrometer for size-distribution measurement. The inlet aerosol passes through a single-stage impactor ...
