Atmospheric Science Data Collection from the Denman Marine Voyage of the RSV Nuyina, 2025

Published: 2025-04-29

These data were collected on voyage 3 of the RSV Nuyina in the 2024/2025 season. The voyage was colloquially known as the "Denman Marine Voyage", as it operated in the vicinity of the Denman Glacier. This dataset provides detailed measurements of aerosol particle microphysical properties of particle number size distribution using a Scanning Mobility Particle Sizer (SMPS), total particle number concentration using a Condensation Particle Counter (CPC) model number 3776 and 3772 for diameters greater than 3 and 10 nm, respectively, and cloud condensation nuclei (CCN) number concentration using a CCN counter, profiles of the vertical thermodynamic structure (temperature, pressure, relative humidity, wind direction/speed) using radiosondes, and remote sensing of microphysical cloud/precipitation properties including brightness temperatures across 35 channels, precipitable water, and liquid water path using the microwave radiometer. (MWR) The MWR also provides retrieved atmospheric profiles of temperature, relative humidity, and precipitable water. Precipitation properties were observed with the microrain radar (MRR) which measures reflectivity, vertical velocity, and doppler spectra properties. Cloud properties were detected with the Micropulse lidar (MPL) which measures co-polarization power and cross-polarization power.
