Research Activities

MS&OSR 3rd Lab Fig. 2 MS&OSR 3rd Lab Fig. 1 Lidar is one of the remote sensing instruments using laser light pulse, which can measure the spatial and temporal distribution of atmospheric minor constituents such as water vapor, aerosols including Aeolian dust, optically thin clouds, ozone, nitrogen dioxide and carbon dioxide. In this laboratory, we cover wide range research areas from basic development and observation to applied research. We develop instruments, observe the atmosphere, validate and utilize for the numerical model using the data by taking advantage of its high temporal and spatial resolution. For example, we verify and improve the algorithms of satellite-equipped sensors such as GOSAT.
Recently, in particular, we have been developping a compact mobile water vapor Raman lidar to improve the precision and lead time of the local severe rainstorm prediction. Water vapor present at altitudes between about 100 m and a few kilometers plays a very important role in the rainstorm mechanism. The observational data taken by the lidar at multiple points will be used to verify and improve the numerical weather prediction model.
With regard to the aerosols and ozone, long term observations of the stratospheric aerosols have been made for more than 30 years and observations of the aerosols and tropospheric ozone made at several stations contribute to the GOSAT retrieval algorithm.
