Abstract Observations have been carried out by means of imawari‐8 satellite from space and lidar systems from surface to retrieve aerosol optical properties. The high temporal resolution of imawari‐8 satellite is employed to derive the surface reflectance using band to and brightness temperature using band to . The near‐surface aerosol extinction profiles, on the other hand, are measured using a plan position indicator PP lidar coupled with a slant path SP lidar as well as ground‐based sampling instruments. The wavelengths are and nm for PP 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 PP lidar is compared with the aerosol distribution derived from satellite data of imawari‐8, in addition to less frequently observed Landsat‐8 and MODS imagery. n this paper, we describe recent results of our analysis based on lidar observations synchronized with satellite overpass. Keywords: Boundary‐layer aerosol; PP lidar; Mie scattering; Satellite data analysis.

1. Introduction

Aerosols are liquid and solid particles originated from both natural and anthropogenic sources particles. Aerosols exerts impact on radiation balance of the Earth atmosphere directly and indirectly that can be analyzed by employing their physical properties PPC . To obtain better understanding of aerosols, we need the monitoring technique that enables the retrieval of their optical properties. Optical remote Corresponding author.
