1. The Japanese Reanalysis for Aerosol (JRAero) is a global aerosol reanalysis product construnted by the Meteorological Research Institute (MRI) of the Japan Meteorological Agency (JMA) and the Research Institute for Applied Mechanics (RIAM) of Kyushu University (KU).
1. Yunmimoto 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..
