Dataset: Spectral magnitude data for 0.0008 ppm bands from aerosol water soluble organic matter 1H NMR spectra from R/V Knorr GEOTRACES cruises KN199-04 and KN204-01 in the Subtropical northern Atlantic Ocean in 2010 and 2011

The sampling details and identities of each of the samples is provided in addtion to the NMR data. This includeds: starting and ending locations (latitudes and longitudes) and times (Greenwich mean time) as well as the sampling rates (m3 min-1) and calculated sample volumes (m3) for each of the aerosol samples. The run times (measured in hours) and sample volumes account for periods when the sampler was stopped due to potential contamination from the ship’s stack. The NMR data are reported as spectral intensity units, which are non-quantitative, and chemical shift - at parts per million difference from a reference signal, the hydrogens in tetramethylsilane. Spectral images are also provided as JPEG files. These images show the NMR spectra from which the numerical data are derived.
