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 ...

Grimm is a partner of the Eurek4a campaign

What is the importance of clouds climate change? Since beginning of 2020, an international team of researcher is working on this question as part of the large-scale study EUREC4A. The effect of aerosols is also investigated on - with high-tech ...

Indoor Wide Range Aerosol Spectrometer

The Indoor Wide Range Aerosol Spectrometer combines two technologies for particle counting and classifying: a Scanning Mobility Particle Sizer (SMPS+C) with a butanol condensation particle counter for nanoparticles and the portable optical aerosol spectrometer (11-D) for dust particles. The system can be used for accurate and high resolution measurements of the entire particle size range from 5 ...
