Short summary
MBTCA (3-methyl-1,2,3-butanetricarboxylic acid), a second-generation product of monoterpenes, is one of the most relevant tracer compounds for biogenic secondary organic aerosols (SOAs). Laboratory-generated, micrometer-sized, pure-MBTCA, mono-/di-/trisodium MBTCA salts and MBTCA–NaCl mixture aerosol particles were examined systematically to observe their hygroscopic behavior, and it was also observed that the monosodium MBTCA salt aerosols were formed through a reaction between MBTCA and NaCl.
