ACE-1: R/V Discoverer H-TDMA 050nm Aerosol Data. Version 1.0

This dataset contains measurements from the Hygroscopic Tandem Differential Mobility Analyser (H-TDMA) aboard the NOAA R/V Discoverer during the ACE-1 voyage from Seattle, USA to Hobart, Australia. Measurements for 50nm dry sizes were performed at 90% relative humidity. These data consist of date/time (UTC), relative humidity (DMA2), julian day, run no., dry size, lst hydroscopic peak parameters (aerosol fraction, beta factor, growth dispersion factor), 2nd and 3rd hydroscopic peak parameters (if observed), and latitude/longitude. This dataset was quality assured and fulfilled a number of criteria based mainly on temperature and relative humidity stability in DMA2 and influence from ship pollution.

本数据集包含美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）“发现者号”科考船（R/V Discoverer）在ACE-1航次（从美国西雅图前往澳大利亚霍巴特）中搭载的吸湿性串联差分迁移率分析仪（Hygroscopic Tandem Differential Mobility Analyser，简称H-TDMA）所获取的测量数据。针对50纳米干粒径的测量在90%相对湿度条件下开展。该数据集包含协调世界时（Coordinated Universal Time，UTC）下的日期/时间、DMA2相对湿度、儒略日、运行编号、干粒径、一阶吸湿性峰值参数（气溶胶占比、β因子、增长分散因子）、二阶及三阶吸湿性峰值参数（若观测到），以及经纬度。本数据集已完成质量保证，且满足若干基于DMA2温湿度稳定性及船舶污染影响的判定标准。
