We have found some numerical errors in our paper “The
role of ammonia in sulfuric acid ion induced nucleation”
by I. K. Ortega et al. (Atmos. Chem. Phys., 8, 2859–
2867, 2008). We discovered that i...

A detailed description of the WAD/SJAC and the analytical
procedures is given elsewhere (Slanina et al., 2001; Wyers
et al., 1993). A simplified sketch of the sampling system
is shown in Fig. 2. Th...
