This study assesses the ability of the recent chemistry version (v3.3) of the Weather Research and Forecasting (WRF-Chem) model to simulate boundary layer structure, aerosols, stratocumulus clouds, and energy fluxes over the Southeast Pacific Ocean. Measurements from the VAMOS Ocean-Cloud-Atmosphere-Land Study Regional Experiment (VOCALS-REx) and satellite retrievals (i.e., products from the MO...

The Chinese environmental satellites HJ1 A and B can play a significant role in the aerosol retrieval due to their high spatial and temporal resolution. The current Aerosol Optical Depth (AOD) retrieval methods from HJ1-CCD are almost based on the LUT (Look-Up Table), by selecting the best fitting result to determine the AOD. However, aerosol model selection has an important impact on the retri...

10 Light scattering and absorption properties of atmospheric aerosols are of vital importance in 11 evaluating their types, sources and radiative forcing. This is of particular interest over the 12 Gangetic-Himalayan (GH) region due to uplift of aerosol from the plains to the Himalayan range 13 causing serious effects on atmospheric heating, glaciology and monsoon circulation. In this 14 respec...

Clouds are one of the main regulating factors of the Earth’s climate through scattering and absorption of solar radiation as well as emission and absorption of thermal radiation. In consequence, the study of cloud properties is extremely important for understanding their role in climate change mechanisms. Specifically, aerosol particles, natural or anthropogenic, influence cloud-related process...

Light scattering and absorption properties of atmospheric aerosols are of vital importance for evaluating their types, sources and radiative forcing. This is of particular interest over the Gangetic–Himalayan (GH) region due to uplift of aerosol from the plains to the Himalayan range, causing serious effects on atmospheric heating, glaciology and monsoon circulation. In this respect, the Ganges...

We examine the impact of incorrect atmospheric correction, specifically incorrect aerosol model selection, on retrieval of bio-optical properties from satellite ocean color imagery. Uncertainties in retrievals of bio-optical properties (such as chlorophyll, absorption and backscattering coefficients) from satellite ocean color imagery are related to a variety of factors, including errors associ...

INTRODUCTION This study investigated the performance of electronic cigarettes (e-cigarettes), compared different models within a brand, compared identical copies of the same model within a brand, and examined performance using different protocols. METHODS Airflow rate required to generate aerosol, pressure drop across e-cigarettes, and aerosol density were examined using three different proto...

With the recently promulgated PM2.5 mass standards, a need has appeared for continuous PM2.5 mass measuring instrumentation to complement standard filter based aerosol samplers. It is generally accepted that in most cases, the PM2.5 mass distribution and light scattering is dominated by particles with diameters in the size range 0.1–1.0μm. Early field studies indicated a reasonable correlation ...
