Professional Expertise:
Professor Hayashida has experiences in stratospheric aerosol observation by using lidar and has been interested in the effect of heterogeneous reactions on stratospheric aerosols upon ozone destruction. After moving to Nara Women's University she started satellite data analysis including Improved Limb Atmospheric Spectrometer (ILAS), Stratospheric Aerosol and Gas Experiment (SAGE) II and other satellite sensors. She contributed to the ILAS Science Team as a leader of validation for aerosol extinction measurements. She investigated the composition of Polar Stratospheric Clouds (PSCs) and their effects on chemical processes related to polar ozone destruction, by utilizing ILAS data. Her group also developed a new simple scheme to construct synoptic maps of chemical species by combining trajectory mapping with a photochemical box model (Chemical Species Mapping on Trajectories). She received Horiuchi Award from Japan Meteorological Society in 2002 for her scientific achievements. Later she extended her study to tropospheric ozone, focusing on the spatiotemporal variation of tropospheric ozone distribution.
She was a member of SPARC SSG from 2005 through 2008, and contributed to the joint scientific meeting of SPARC/IGAC in Kyoto, 2009 as one of the organizing committee members.
Research Interests:
Her most recent interest is methane emission from agriculture. Among anthropogenic emissions of methane, more than 40% is estimated to be from agricultural sources, including rice cultivation, ruminant animals, and animal wastes. However, the strength of individual sources of methane remains uncertain, in spite of the importance of the effect on global warming. Monsoon Asia, where approximately 90% of the world's rice fields are located, is one of the major source regions of methane, and further investigations are needed for the region. She is now investigating methane distribution observed by Greenhouse gases Observing SATellite (GOSAT) and other satellite sensors, focusing on Monsoon Asia, as one of the RA researchers of the GOSAT project.
