  3. TSI nephs observed lower values than Rad Res neph Zeppo which • was operated at ambient conditions. • 2. Total scattering of TSI-neph-IAG is 20% lower than TSI-neph-LFA at 550 nm. • 3. It is interesting that there is no offset in the slops, only factor is applicable. • 4. Rad-Research-Nephs were calibrated and intercompared at fazenda • in parallel configurations (Fihure2). The results shown above are after • applying all the corrections i.e. (calibration with zero air and CO2; • intercomparison with ambient air and NaCl particles, • the truncation correction based on the Guyan et al 2003). Using all the • analysis an offset of 1(Mm-1) is added in zeppo observations • and all the data are increase by 2% i.e. a factor of 1.02. • 5. The the Rad-research-Neph-Zeppo (sampling ambient aerosols) observes • higher than the Rad-Res-neph-Groucho (sampling dry aerosols with • impactor cut off at about 1 micro meter). This difference is expected. • We need to resolve • Why the TSI nephs show lower values than Rad Res neph zeppo. • Why the two TSI are not matching (20% different in each other). • The calibration data for the two TSI nephs can help to resolve these issues.
