Ozone monitoring instrument flight-model on-ground and inflight calibration

Autor: Ernest Hilsenrath, Glen Jaross, Gijsbertus van den Oord, Pieternel F. Levelt, George H. Mount, Matt Kowalewski, Donald F. Heath, R. Dirksen, Marcel Dobber, Richard P. Cebula

Publikováno v: International Conference on Space Optics — ICSO 2004.

The Ozone Monitoring Instrument (OMI) is an ultravioletvisible imaging spectrograph that uses two-dimensional CCD detectors to register both the spectrum and the swath perpendicular to the flight direction. This allows having a 114 degrees wide swath

Retrieved tropospheric and stratospheric BrO columns over Lauder, New Zealand

Autor: Robyn Schofield, Clive D. Rodgers, Martyn P. Chipperfield, George H. Mount, D. Shooter, Karin Kreher, A. Thomas, Paul Johnston, Brian J. Connor

Spectroscopic measurements of BrO using direct sun and zenith-sky viewing geometries are combined in an optimal estimation retrieval algorithm to obtain tropospheric and stratospheric columns of BrO. Seventy-two twilight periods are investigated over
