Major aerosol instruments consisted of CN with diameters Dp > 10 nm (TSI 3760), UCN with diameters Dp >3 nm (TSI 3025), radial differential mobility analyzer (RDMA) size distribution Dp 8 to 250 nm, and a laser optical particle counter (OPC-PMS LAS-X) size distribution Dp, 150 to 7000 nm. RDMA dry surface areas at about 25% RH can be multiplied by about 3 to estimate ambient surface areas at 94% RH.
17. 3, NMHCs, and UV irradiance were continuously recorded as were the meteorological parameters RH and T; for details see (J. Hoell et al., ibid., in press). The above species and parameters were typically measured and averaged over times ranging from 15 s to 5 min. A subset of these (for example, vertical and horizontal winds, dew point, and temperature) was high-resolution 20-Hz data.

Calculated J values were scaled for cloud effects based on a comparison of the observed OH with model estimated values (typically 10%).
