AB  - A thorough understanding of chemical composition, particle pH, and pollutant 
      emissions is essential to address the climate and human health effects of 
      atmospheric particles. In this study, we used a High-Resolution Time-of-Flight 
      Aerosol Mass Spectrometer (HR-ToF-AMS) and Scanning Mobility Particle Sizer 
      (SMPS) to characterize the composition of submicron particles. Moreover, we 
      applied the ISORROPIA-II model to analyze the particle acidity effect on the 
      compositional characterization of submicron particles from December 22, 2016 to 
      January 7, 2017 in Albany, New York, USA. The results indicated that aerosols 
      with mobility diameter from SMPS in the range 200-400 nm were the main 
      contributors to the mass during the measurement period. The dominance of organics 
      (47%) and sulfate (16%) was similar to previous observations in the eastern 
      United States in Winter 2015, while the fraction of nitrate (23%) was much 
      higher. Moreover, nitrate could easily form at colder temperatures and lower RH 
      levels even when there were more acidic particle periods during the measurement 
      period in Albany. The ISORROPIA-II model indicated that there were more acidic 
      particles, which was estimated using pH values. Lower temperature conditions 
      tended to favor nitrate formation. The nitrate concentration exceeded that of 
      sulfate in the measurement period, even though the SO(2) and NO(x) emissions were 
      similar. The organics in submicron particles were strongly influenced by the 
      local emissions in winter. However, the inorganic compounds in submicron 
      particles could be derived from regional transport as their pollution sources 
      originated from different directions. This may help strategize emission 
      reductions in the future.
