ICECAPS-ACE: Vertical aerosol particle size distributions from the University of Leeds POPS 0307 instrument collected via Helikite balloon above Summit Station, Greenland, July-August 2023
Abstract
This dataset contains vertically resolved aerosol particle size distribution measurements collected using a tethered balloon platform at Summit Station, Greenland, in July and August 2023.
Aerosol particle size distributions were measured by a Handix Portable Optical Particle Spectrometer (POPS 1120, S/N: 0307). The POPS was placed in a lightweight insulating foam box, and a coarse mesh filter was placed over the inlet to prevent the growth of rime ice. The POPS was secured to the kite wing on the tethered balloon such that the inlet was always oriented into the wind.
These data were collected as part of the joint Natural Environmental Research Council (NERC) and US National Science Foundation (NSF) -funded Integrated Characterisation of Energy, Clouds, Atmospheric state, and Precipitation at Summit - Aerosol Cloud Experiment (ICECAPS-ACE) project.
