Terpenoids Measured during LAAQC-2020 and -2022_UCR_NOAA

This dataset reports mixing ratios (ppt) for terpenoids measured in Pasadena, CA during Los Angeles Air Quality Campaign (LAAQC) 2020 and 2022. The samples were collected at Caltech campus with lat and lon reported in the metadata. Samples were collected onto dual sorbent bed (100 mg Tenax TA 35/60 and 200 mg Carbograph 1 TD 60/80 inseries) cartridges and then analyzed using automated thermal desorption (ATD) system coupled to a Pegasus 4D GC/GC-TOF-MS. Sampling and analysis procedures for LAAQC-2020 are described in Van Rooy et al. (2021, https://doi.org/10.1021/acsearthspacechem.1c00248). The project was funded by the NOAA AC4 NA21OAR4310222
