[1997]. We use dG = -0.8 to account for a SF6 calibration scale change. This term no longer represents only a delay from the surface to the tropopause. The mean age error reported is solely based on the SF6 measurement precision and is thus useful in comparing ACATS ages from different flights. Absolute accuracy of the SF6 measurement and any systematic errors in the method used to calculate mean ages are not included. Organic chlorine (CCly) was calculated from ACATS in-situ measurements of CFC-11, CFC-12, CFC-113, CH3CCl3, and CCl4. Contributions to CCly from CH3Cl and HCFC-22 (measured by WAS) were calculated from their correlations with tracers measured by ACATS. Organic bromine (CBry) was calculated from ACATS in-situ measurements of halon-1211. Contributions to CBry from CH3Br, halon-2402, halon-1301, CH2Br2, and CH2BrCl (measured by WAS) were calculated from their correlations with tracers measured by ACATS using the formula in Wamsley et al. [1997]. The total chlorine (TotalCl) and total bromine (TotalBr) content of each sampled air mass was calculated from the documented tropospheric trends of chlorinated and brominated trace gases (e.g., Montzka et al. [1996]) and weighted with a mean age spectrum calculated by Hall & Plumb [1994]. Inorganic chlorine (Cly) and inorganic bromine (Bry) were calculated as TotalCl-CCly and TotalBr-CBry, respectively. Data submitted only for air masses with potential temperature greater than 380 K. 1 GMTs Age AgeERR TotalBr CBry Bry TotalCl CCly Cly 26522 9999.00 9999.00 9999.000 9999.000 9999.000 9999.000 9999.000
