Extended Data Table 1 Comparison of CLOUD experimental conditions with the ambient conditions during CAFE-Brazil research flight RF 19, periods T4 and T9 (Curtius et al.13)

From: New particle formation from isoprene under upper-tropospheric conditions

  1. The times of the CB flights are in local time. *Only CLOUD experiments with added NOx. †The definitions of IP0N and IP1-2N in the CB study refer to the measurement of the NO3− chemical ionization alone, whereas the CLOUD results refer to measurements using the combination of NO3−, Br− and NH4+ chemical-ionization methods. ‡Only CLOUD experiments with H2SO4. §The CLOUD limit-of-detection (LOD) for H2SO4 is 2 × 104 cm−3. ||The CB LOD for H2SO4 is 2 × 106 cm−3 at altitudes above 8 km. Only experiments with HIO3. #The CLOUD LOD for NO is 2 × 108 cm−3. ☆Using equation 7 in ref. 35. **Using equations 1–4 in ref. 35.
