Observation of Aerosol Optical Properties by Means of Himawari-8 Satellite from Space and Lidar System from Surface

[ABSTRACT]Observations have been carried out by means of Himawari-8 satellite from space and lidar systems from surface to retrieve aerosol optical properties. The high temporal resolution of Himawari-8 satellite is employed to derive the surface reflectance using band 1 to 6 and brightness temperature using band 7 to 16. The near-surface aerosol extinction profiles, on the other hand, are measured using a plan position indicator (PPI) lidar coupled with a slant path (SP) lidar as well as ground-based sampling instruments. The wavelengths are 349 and 532 nm for PPI and SP lidars, respectively. The general intention of these observations is twofold. First, we verify the consistency of the lidar data in retrieving aerosol extinction with the aerosol data measured using sampling instruments, namely an integrating nephelometer, aethalometer, and an optical particle counter. The difference in humidity conditions between the instrumental and ambient conditions is taken into account through the Mie-scattering calculation. Second, the horizontal distribution measured with the PPI lidar is compared with the aerosol distribution derived from satellite data of Himawari-8, in addition to less frequently observed Landsat-8 and MODIS imagery. In this paper, we describe recent results of our analysis based on lidar observations synchronized with satellite overpass.
