R/V Discoverer H-TDMA 050nm Aerosol Data (leg 1)
https://data.eol.ucar.edu/dataset/11.903

Summary
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.
