8 Species measured by PANTHER and UCATS Fred Moore, Eric Hintsa, Dale Hurst, Jim Elkins PANTHER (6-Channel GC): ECD channels: N 2 O, SF 6, CCl 2 F 2 (CFC-12),) CCl 3 F (CFC-11), and CBrClF 2 (halon-1211) injected every 70 seconds, and H 2, CH 4, CO, CCl 4, CH 3 CCl 3 (methyl chloroform) and PAN (peroxyl acetyl nitrate) injected every 140 seconds. The width of a sample load on an ECD channel is only 3 seconds, allowing this data set to correlate well with other fast measurements. MSD channels: The methyl halides CH 3 I, CH 3 Br, CH 3 Cl, the sulfur compounds COS, CS 2, the hydrochlorofluorocarbons CHClF 2 (HCFC-22), C 2 H 3 Cl 2 F (HCFC-141b), C 2 H 3 ClF 2 (HCFC-142b), and the hydrofluorocarbon C 2 H 2 F 4 (HFC-134a) are injected every 180 seconds with 150 seconds sample load width. This data set correlates with a time average of other fast measurements. UCATS: 2-Channel GC: every 70 s (N 2 O, SF 6 ) or every 140 s (H 2, CH 4, CO) TDL: 10-second average H 2 O Photometer: 1-Hz O 3

33 Summary and conclusions HIPPO provides a new type of data for CO 2 and GHG studies: global, extremely fine grained, many tracers. Major transport processes are clearly delineated, some not captured well by models—the warm conveyor belt (intense, persistent, ensemble of small scale processes), Arctic Cold Dome, and Antarctic marine PBL are examples. Multiple tracers shine a light into the "Modelers' Closet"—quantitatively confront global models with fine scale data (reaction vs. transport time scales). Source/sink regions are revealed and impacts quantified—N 2 O in the tropics and Antarctic, marine reactive species. The data will be completely public as soon as possible, to encourage their use.
