Aerosol detection and monitoring by satellite observations has been substantially developed over past decades. While several state-of-art aerosol retrieval techniques provide aerosol properties in global scale, the more detail characteristics remain unknown because most of the satellite sensors are limited to 1km resolution observations. However, a new aerosol retrieval algorithm for the Modera...

Atmospheric aerosols play very important roles in climate change and air particulate pollution. Due to their highly variable optical and physical properties as well as to short atmospheric lifetimes and large spatial and temporal gradients, the aerosol impact on climate models and air pollution is really a complex task. Lidars based on elastic scattering have been largely used to measure aeroso...

The possible interaction and modification of cloud properties due to aerosols is one of the most poorly understood mechanisms within climate studies, resulting in the most significant uncertainty as regards radiation budgeting. In this study, we explore direct ground based remote sensing methods to assess the Aerosol-Cloud Indirect Effect directly, as space-borne retrievals are not directly sui...

The Geostationary Ocean Color Imager (GOCI) onboard the Communication, Ocean, and Meteorological Satellite (COMS) is the first multi-channel ocean color imager in geostationary orbit. Hourly GOCI top-of-atmosphere radiance has been available for the retrieval of aerosol optical properties over East Asia since March 2011. This study presents improvements made to the GOCI Yonsei Aerosol Retrieval...

This paper presents a new method for simultaneously retrieving aerosol and surface reflectance properties from combined airborne and ground-based direct and diffuse radiometric measurements. The method is based on the standard Aerosol Robotic Network (AERONET) method for retrieving aerosol size distribution, complex index of refraction, and single scattering albedo, but modified to retrieve aer...

Aerosols play an important role in atmospheric physics. The airborne particles in diameters of a few nanometres to some micrometres affect the climate system by altering the energy balance of the atmosphere. However, the quantification of the climate effect is an open question until today. Large uncertainties exist in the knowledge of the global aerosol distribution and their properties. The pr...

This document describes the algorithms for simultaneous remote sensing of aerosol from EOS-MODIS over land and ocean. The algorithm will be used to monitor the aerosol optical thickness (proportional to the aerosol total loading) and size distribution (integrated on the vertical column) of the ambient (undisturbed) aerosol, over most of the globe (oceans and the moist parts of the continents) o...

The topic of cloud radiative forcing associated with the atmospheric aerosol has been the focus of intense scrutiny for decades. The enormity of the problem is reflected in the need to understand aspects such as aerosol composition, optical properties, cloud condensation, and ice nucleation potential, along with the global distribution of these properties, controlled by emissions, transport, tr...

[1] Characteristics of optical and chemical properties of dust aerosol over Beijing and their relation were studied in the spring dust season, 2006 to understand the impact of dust and anthropogenic aerosol on the regional climate. Two dust plumes (DS1 and DS2) were identified with contrasting physicochemical properties. Strong absorbing of aerosol at 439 nm was observed, probably due to the si...

Airborne high spectral resolution lidar observations over Europe during the EUCAARI-LONGREX field experiment in May 2008 are analysed with respect to the optical properties of continental pollution aerosol. Continental pollution aerosol is characterized by its depolarisation and lidar ratio. Over all, the measurements of the lidar ratio and the particle linear depolarization ratio of pollution ...
