    Description:

    Metadata record for data from AAS (ASAC) project 3229. Public Summary: We investigate the impact of Black Saturday Australian bushfire in 2009 on the atmosphere above Australia and in the southern hemisphere in general, including Antarctica. Using high quality measurements collected by modern satellite and ground-based instruments, we study vertical and horizontal motion of the smoke plume, chemical composition of this plume, and chemical reactions between various molecules in the plume and other atmospheric gases. We want to answer an important question on how the bushfire plume may interact with the ozone molecules and whether it adds to the depletion of the protective ozone layer above Australia and above Antarctica. Project Objectives: - Using satellite and ground-based measurements, investigate the horizontal and vertical transport of the plume that resulted from Black Saturday Australian bushfire in February 2009. This includes analysis of the short-term (within one month) and long-term (up to several years) transport of plume material. Perform this analysis for other significant bushfire events that may occur in the southern hemisphere throughout the duration of this project and result in the injection of plume material into the stratosphere. - Study the evolution in chemical composition of stratospheric aerosols associated with Black Saturday bushfire and other significant pyrocarbon events. - Analyse the short- and long-term effects of Black Saturday bushfire and other significant pyrocarbon events in the southern hemisphere on the stratospheric ozone concentration at various locations and in particular on the Antarctic ozone hole. - Analyse the climate impact of bushfire plume material injected into the stratosphere. Taken from the 2010-2011 Progress Report: - We used the Odin/OSIRIS and CALIPSO satellite data and investigated the horizontal and vertical transport of the Australian-2009 Black Saturday bushfire smoke plume in the stratosphere in February-June 2009. - We identified the enhanced water absorption bands in the OSIRIS spectra of smoke plume. We are currently studying this smoke hydration in the stratosphere using multiple satellite instruments. A paper for Geophysical Research letters is currently in preparation. - We are currently investigating the horizontal spread of bushfire smoke material to all locations in the Northern and Southern hemispheres, up to the polar regions. 2012-11-12 Update The data are from the OSIRIS (Optical Spectrograph and Infrared Imager System) instrument on the Odin satellite. The exact data used in project 3229 are: Level 1 spectral solar irradiances measured by OSIRIS in February - June 2009. The detailed description of the wavelengths used and the approach to data analysis are given in the paper: Siddaway, J. M. and S. V. Petelina (2011), Transport and evolution of the 2009 Australian Black Saturday bushfire smoke in the lower stratosphere observed by OSIRIS on Odin, J. Geophys. Res., 116, D06203, doi:10.1029/2010JD015162.

  • Odin OSIRIS data products

    https://cmr.earthdata.nasa.gov/search/concepts/C2119689615-ESA.xml
    Description:

    The Odin OSIRIS (Optical Spectrograph and Infra-Red Imaging System) data provides vertical profiles measures of spectrally dispersed, limb scattered sunlight from the upper troposphere into the lower mesosphere. The data products are regularly processed and provide Ozone density vertical profiles (both Level 2 and Level 3), vertical profiles of stratospheric Aerosol (both Level 2 and Level 3), slant column densities of nitrogen dioxide NO2 profiles (Level 2), stratospheric BrO profiles (Level 2)

    Description:

    The latest Odin Sub-Millimetre Radiometer (SMR) datasets have been generated by Chalmers University of Technology and Molflow within the Odin-SMR Recalibration and Harmonisation project (http://odin.rss.chalmers.se/), funded by the European Space Agency (ESA) to create a fully consistent and homogeneous dataset from the 20 years of satellite operations. The Odin satellite was launched in February 2001 as a joint undertaking between Sweden, Canada, France and Finland, and is part of the ESA Third Party Missions (TPM) programme since 2007. The complete Odin-SMR data archive was reprocessed applying a revised calibration scheme and upgraded algorithms. The Level 1b dataset is entirely reconsolidated, while Level 2 products are regenerated for the main mesospheric and stratospheric frequency modes (i.e., FM 01, 02, 08, 13, 14, 19, 21, 22, 24). The resulting dataset represents the first full-mission reprocessing campaign of the mission, which is still in operation.
