Alpha-pinene and methyl salicylate mixing ratios collected on the ATTO INSTANT tower in October 2024

This dataset contains the abundances of (-)-alpha-pinene, (+)-alpha-pinene and methyl salicylate in the Amazon rainforest canopy given as mixing ratios with units of parts per trillion (pptV) and percentage uncertainties. The data was processed from cartridge samples taken at 23m on the ATTO IINSTANT tower during 9th October 2024 to 23rd October 2024. Samples were taken every 1.5 hours for 30 minutes. Sampling start and end times are given as local Manaus time (UTC-4).
