TL;DR: An hierarchical algorithm is reported, which can effectively reduce the hyperspectral data to intrinsic dimensionality and shows that reduced data obtained by hierarchical PCA can compare favorably to the results obtained from original data.

TL;DR: In this article, the authors used the Microwave Sounding Unit (MSU) data for long-term observations of atmospheric temperatures acquired from the MSU since 1979-2008 and found that the unequal distribution of the warming trend over the year is partially attributed to a number of controlling factors such as sunlight duration, CO2 trends over the region (2003-2008), water vapor and aerosol distribution.

TL;DR: In this paper, the authors used multi-sensor data to study the characteristics of dust storms over the Indo-Gangetic basin and found that these data show characteristic behavior of brightness temperature and Aerosol Index due to dust, which change significantly as dust migrates towards east over Kanpur.

TL;DR: In this article, three years (2006-2008) of ground-based observations of the Aerosol Optical Depth (AOD) in the urban environment of Athens, in the Eastern Mediterranean, are analyzed.

TL;DR: In this article, a quasi-operational experimental airborne dust forecast system predicted the 2011 dust storm and provided model output for continuing analysis in collaboration with public health and air quality communities.
