, Development of an aerosol reanalysis product - JRAero, 14th iCACGP Symposium/15th IGAC Science Conference, 2018.09, As well as meteorological reanalysis products (e.g., ERA, MERRA and JRA), reanalysis products for aerosol components are under development and ready for research use. A global aerosol reanalysis product named the Japanese Reanalysis for Aerosol (JRAero Version 1) was constructed by the Meteorological Research Institute (MRI) of Japan Meteorological Agency (JMA) and Research Institute for Applied Mechanics (RIAM) of Kyushu University (Yumimoto et al., Geosci. Model Dev., 2017). The reanalysis employs a global aerosol transport model developed by MRI (MASINGAR mk-2), a 2-dimensional variational assimilation method, and maps of aerosol optical depth (AOD) from the Moderate Resolution Imaging Spectroradiometer (MODIS) onboard Terra and Aqua satellites with horizontal resolution of TL159 (approximately 1.1°× 1.1°). Reanalysis products, including global distributions of AOD (for total and each aerosol component), surface PM2.5 concentration, and deposition amounts etc. are now available through the JRAero web site (https://www.riam.kyushu-u.ac.jp/taikai/JRAero/), and will be useful for various applications (e.g., climatological analyses of aerosol and its climate effect, epidemiologic studies of PM2.5, estimates of aerosol exposure and its health impact, and determination of the initial and boundary conditions of numerical models). In this presentation, we will overview setup of the reanalysis and indication of its quality as well as some research results with the reanalysis product.. |

Tanaka, Naga Oshima, Takashi Maki, Development of the aerosol reanalysis product (JRAero) and its use in aerosol researches in East Asia, Asia Oceania Geosciences Society, 15 th Annual Meeting, 2018.06, As well as meteorological reanalysis products (e.g., ERA, MERRA and JRA), reanalysis product for aerosol components are under development and ready for research use. A global aerosol reanalysis product named the Japanese Reanalysis for Aerosol (JRAero Version 1) was constructed by the Meteorological Research Institute (MRI) of Japan Meteorological Agency (JMA) and Research Institute for Applied Mechanics (RIAM) of Kyushu University. The reanalysis employs a global aerosol transport model developed by MRI (MASINGAR mk-2) and a 2-dimensional variational method, assimilates maps of aerosol optical depth (AOD) from the Moderate Resolution Imaging Spectroradiometer (MODIS) onboard Terra and Aqua satellites every 6 hour, and has horizontal resolution of TL159 (approximately 1.1°× 1.1°). Reanalysis products, including AOD (total and each aerosol component (dust, sulfate, sea salt, BC, OC)), surface PM2.5 and PM10 concentrations, and wet and dry depositions for each aerosol component etc. are now available through the JRAero web site (https://www.riam.kyushu-u.ac.jp/taikai/JRAero/), and would be useful for various applications (e.g., climatological analyses of aerosol and its climate effect, epidemiologic studies of PM2.5, estimates of aerosol exposure and its health impact, and determination of the initial and bounbary conditions of numerical models). In this presentation, we will overview setup of the reanalysis and indication of its quality as well as some research results with the reanalysis product.. |

Yumimoto K., Aerosol Data Assimilation with Lidar Observations (invited), 28th International Laser Radar Conference, 2017.06, Data assimilation is a technique to fuse numerical model and observations (1) to obtain the more accurate state for forecasts (initial value problem), (2) to optimize parameters (e.g., emissions) (inversion), (3) to generate a uniform, continuous, and best-estimated data product (reanalysis), and (4) to investigate the potential impact of observing system. In this presentation, we will introduce studies about aerosol data assimilation with both ground-based and space-borne lidar observations.. |
