The Ozone Distribution Above the Asian Monsoon as seen by the OSIRIS Instrument from 2002-Present

Abstract:

The Canadian built OSIRIS instrument measures spectrally dispersed limb scattered sunlight from low earth, sun-synchronous orbit onboard the Swedish led Odin spacecraft. OSIRIS and Odin have been in operation since the autumn of 2001 and during this time the OSIRIS measurements, from 280 nm to 810 nm over a tangent altitude range from 10 km to 65 km, have been used to routinely retrieve moderate high vertical resolution ozone profiles over the entire globe from 82 degrees north to 82 degrees south. As these measurements are concentrated in the northern hemisphere and known for their high quality including excellent precision, accuracy and stability they are ideal for the study of the time evolution of the ozone distribution in the region of the Asian Monsoon. This poster will describe the OSIRIS ozone data product, its characterization using other spacecraft and ground based instruments and its utility for process studies related to the Asian Monsoon. Along with the data description features relevant to the Asian Monsoon will be extracted from the OSIRIS ozone data record and discussed in the context of what is known about the dynamics of this interesting region.
