Non-Volatile Marine and Non-Refractory Continental Sources of Particle-Phase Amine During the North Atlantic Aerosols and Marine Ecosystems Study (NAAMES)
Amines were measured by aerosol mass spectrometry (AMS) and Fourier Transform Infrared (FTIR) spectroscopy during the North Atlantic Aerosols and Marine Ecosystems Study (NAAMES) cruises. Both AMS non-refractory (NR) amine ion fragments comprising the AMS CxHyNz family and FTIR non-volatile (NV) ami...
