Sensitivity of multiangle imaging to natural mixtures of aerosols over ocean
Multiangle remote sensing data can discriminate among aerosol air mass types, as represented by climatologically probable, external mixtures of component particles. Retrievals are performed over a comparison space of four-component mixtures, selected from six commonly observed components having assumed, fixed microphysical properties but with mixing ratios free to vary from 0% to 100%. We refer...
متن کاملRemote sensing of vertical distributions of smoke aerosol off the coast of Africa
[1] In 2004 NASA plans to launch the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations— CALIPSO mission, with a two-wavelength lidar aboard. CALIPSO will fly in formation with the Moderate Resolution Imaging Spectro-Radiometer (MODIS) on the Aqua satellite. Here we present inversions of combined aircraft lidar and MODIS data to study the properties of smoke off the southwest co...
متن کاملAn overview of ACE-Asia: Strategies for quantifying the relationships between Asian aerosols and their climatic impacts
[1] The International Global Atmospheric Chemistry Program (IGAC) has conducted a series of Aerosol Characterization Experiments (ACE) that integrate in situ measurements, satellite observations, and models to reduce the uncertainty in calculations of the climate forcing due to aerosol particles. ACE-Asia, the fourth in this series of experiments, consisted of two focused components: (1) An int...
متن کاملNumerical Study of Heat Transfer and Aerosol Deposition in a Room Environment with Under-floor or Baseboard Heating Systems
In this study, heat transfer and aerosol deposition in the under-floor and baseboard heating systems have been investigated, numerically. The aim of this study is a comparison between these heating systems. This comparison obtains the optimal heating system with low suspended particles in the air. Computational fluid dynamic with Eulerian-Lagrangian method has been used to simulate fluid and pa...
متن کاملPoint and column aerosol radiative closure during ACE 1: Effects of particle shape and size
[1] We used data collected during the First Aerosol Characterization Experiment (ACE 1) to study point and column aerosol radiative closure over the remote ocean. To test point closure, total and hemispheric backscattering coefficients calculated with a Mie singlescattering model were compared with measurements made by ship and aircraft at three wavelengths (400, 550, and 700 nm). On the ship, ...
