A special seminar was made by Dr. Anne M. Thompson (NASA/Goddard Space Flight Center), a distinguished scientist on atmospheric ozone research etc (Host: DCOP and DEGCR).
Her presentation vastly covered important topics of 1) global observations of atmospheric pollutants from OMI (Ozone Monitoring Instrument) satellite sensor, 2) KORUS-AQ mission, an intensive air quality study using NASA DC8 aircraft currently conducted over Korea, and 3) latest status and new results of process analysis from SHADOZ (Southern Hemisphere ADditional OZonesondes).

Speaker: Dr. Anne M. Thompson (NASA/Goddard Space Flight Center)
Title: Updates from NASA/Goddard: Progress on Fighting Pollution & SHADOZ Activities (2016)
Date& Time: 16th May (Mon) 10:15-11:45

Press release was made on the terrestrial CO2 exchange in the mid-high latitudes and tropics as evaluated using two different approaches.

Reliable Estimation for Terrestrial CO2 Exchange Using Ground and Satellite observations
~ Evaluation of Consistency between Two Different Approaches ~

A joint research group led by Dr. Masayuki Kondo, Department of Environmental Geochemical Cycle Research, the Japan Agency for Marine-Earth Science and Technology (JAMSTEC: Asahiko Taira, President) and National Institute for Environmental Studies (NIES: Sumi Akimasa, President) examined consistency between two global terrestrial carbon dioxide (CO2) exchanges based on ground and satellite observation data. It confirmed that using both ground and satellite observations data allows reliable estimation of terrestrial CO2 exchanges at mid and high latitudinal regions in the Northern Hemisphere・・・

Nature publication was made on evaluating north/south hemispheric gradient in atmospheric OH and press released!

Greenhouse Gas*1 Emission Pattern May Need To Be Revised
〜Comprehensive Evaluation of Hydroxyl Radical (OH)*2 Distribution 〜

A joint research team led by Dr. Prabir K Patra, Senior Scientist, Department of Environmental Geochemical Cycle Research, Japan Agency for Marine-Earth Science and Technology (JAMSTEC: Asahiko Taira, President) determined the Northern Hemispheric (NH) to Southern Hemispheric (SH) ratio of the hydroxyl radical (OH) concentration by using JAMSTEC's Atmospheric Chemistry Transport Model (ACTM)*3, highly-accurate observations from surface networks and aircraft campaigns. To estimate the OH concentration ratio, various evaluation methods have been developed since the 1990s; however, this is the first attempt to apply such a multidimensional approach, which accounts for uncertainties in both the model transport and emissions of methyl chloroform (CH3CCl3).・・・

Satellite-based Observations May Be Underestimating Tropospheric NO2 Vertical Column Density (TropoNO2VCD)
~ Light Scattering Effects of Co-existing PM2.5 Aerosols ~

International Research Team led by Dr. Yugo Kanaya, Deputy Director, Department of Environmental Geochemical Cycle Research, Japan Agency for Marine-Earth Science and Technology (JAMSTEC: Asahiko Taira, President) found that satellite observation data of Nitrogen Dioxide (NO2), which is one of air pollutants, had low biases up to 30%~50%. Based on the examination of satellite data using・・・
