The design of the FOZAN-II dual-channel automatic fast-response (1 s) chemiluminescent ozone analyzer for a M55 Geophysica high-altitude aircraft is described. Its measured concentrations range is 10-500 mug/m(3) relative error, less than or equal to 10%; operating temperature range, -95...+40 degreesC; and its operating pressure range, 1100-30 mbar (0-22 km). The device has a built-in reference ozone generator (relative error of <6%) allowing one to autocalibrate the device in flight. Solid-state chemiluminescent sensors manufactured with the use of a coumarin 307 dye and a cellulose-acetate-based substrate have an operation-lifetime exceeding 25 h, are highly sensitive, and are rugged. Results obtained during one of the flights near the South Pole in September 1999 are presented.

Abstract
The design of the FOZAN-II dual-channel automatic fast-response (1 s) chemiluminescent ozone analyzer for a M55 Geophysica high-altitude aircraft is described. Its measured concentrations range is 10-500 mug/m(3) relative error, less than or equal to 10%; operating temperature range, -95...+40 degreesC; and its operating pressure range, 1100-30 mbar (0-22 km). The device has a built-in reference ozone generator (relative error of <6%) allowing one to autocalibrate the device in flight. Solid-state chemiluminescent sensors manufactured with the use of a coumarin 307 dye and a cellulose-acetate-based substrate have an operation-lifetime exceeding 25 h, are highly sensitive, and are rugged. Results obtained during one of the flights near the South Pole in September 1999 are presented.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
