Reports on the composition of ultrafine (<100 nm in diameter) particles in the Amazon are scarce, due in part to the fact that new particle formation has rarely been observed near ground level.  Ultrafine particles near the surface have nevertheless been observed, leaving open questions regarding the sources and chemistry of their formation and growth, particularly as these vary across seasons.  Here we present measurements on the composition of ultrafine particles collected in the Tapaj\'{o}s National Forest (2.857° S, 54.959° W) during three different seasonal periods: 10 - 30 September 2016 (SEP), 18 November - 23 December 2016 (DEC), and 22 May - 21 June 2017 (JUN).  Size-selected (5 - 70 nm) particles were collected daily (22 h) using an offline sampler.  Samples collected during the three time periods were compiled and analyzed using liquid chromatography coupled to Orbitrap high resolution mass spectrometry.  Our findings suggest a sustained influence of isoprene organosulfate..., Date of data collection: 2016-09 to 2017-06
