The impact of a typical pre-monsoon season (April–June) dust storm event on the regional aerosol optical properties and radiation budget in northern India is analyzed. The dust storm event lasted from 17 to 22 April 2010 and the Weather Research and Forecasting model coupled with Chemistry (WRF-Chem) estimated total dust emissions of 7.5 Tg over the model domain. Both in situ (AERONET – Aerosol...

Kawasaki disease (KD) is a rare vascular disease that, if left untreated, can result in irreparable cardiac damage in children. While the symptoms of KD are well-known, as are best practices for treatment, the etiology of the disease and the factors contributing to KD outbreaks remain puzzling to both medical practitioners and scientists alike. Recently, a fungus known as Candida, originating i...

We demonstrate improvements in CALIPSO (Cloud–Aerosol Lidar and Infrared Pathfinder Satellite Observations) dust extinction retrievals over northern Africa and Europe when corrections are applied regarding the Saharan dust lidar ratio assumption, the separation of the dust portion in detected dust mixtures, and the averaging scheme introduced in the Level 3 CALIPSO product. First, a universal, ...

The particle linear depolarization ratio (PLDR) and single scatter albedo (SSA) in 1020 nm from the Aerosol Robotic Network (AERONET) level 2.0 dataset was utilized among 52 stations to identify dust dominated aerosols (DD), pollution mixture (PDM), strongly absorbing (SA) weakly (WA), investigate their spatial temporal distribution, net radiative forcing efficiency global range, further compar...

Although trends in the Aerosol Optical Depth (AOD) have been examined broadly but effects due to prevailing background conditions on these still remain uncertain, for which a multivariate regression trend model has implemented this study. Long-term AOD across globe are obtained from multi-satellite measurements that include MODerate resolution Imaging Spectral-radiometer (MODIS on-board Terra (...

The Satellite Application Facility on Climate Monitoring (CM-SAF) Spectral Resolved Irradiance (SRI) and National Renewable Energy Laboratory Solar Radiation Database Demand (NSRDB-S) satellite-based spectral irradiance products are tested here against benchmark data models at seven ground stations: one in Spain for CM-SAF SRI six North America NSRDB-S. Benchmarks include WISER spectroradiomete...

The large archive of NOAA AVHRR data, covering more than 25 years, bears the potential to detect aerosol trends. However, remote sensing of aerosol optical depth over land is a difficult task, because the aerosol signal gets weaker over bright surface targets and the quality of the retrieval mainly depends on the quality of the surface reflectance estimate. In this study, we test the sensitivit...

MODIS (Terra) aerosol optical thickness product distributed by NSMC were validated over seas around China and its adjacent area using AERONET data from Jan. 2005 to May 2007. Two spatio-temporal matching up schemes were adopted and the results were not quite the same. Using 25km radius and ±0.5h as the sampling window, there were 32 match-ups. The linear fitting results between MODIS and AERONE...
