TL;DR: The Indian Ocean Experiment (INDOEX) documented this Indo-Asian haze at scales ranging from individual particles to its contribution to the regional climate forcing as discussed by the authors, and integrated the multiplatform observations (satellites, aircraft, ships, surface stations, and balloons) with one-and four-dimensional models to derive the regional aerosol forcing resulting from the direct, the semidirect and the two indirect effects.

TL;DR: In this article, the authors present a recommended terminology to clarify the terms used for black carbon in atmospheric research, with the goal of establishing unambiguous links between terms, targeted material properties and associated measurement techniques.

TL;DR: In this article, the TSI 3563 integrating nephelometer is used to reduce and quantify the uncertainties in aerosol optical properties measured with a TSI-3563 integrating NN, which can be used to improve measurement accuracy and quantify uncertainties due to instrumental noise.

TL;DR: In this article, the authors compared commercial and custom-made inversion routines to calculate the particle number size distributions from the measured electrical mobility distribution, and concluded that the consistency of these reference instruments to the total particle number concentration was less than 5%.

TL;DR: In this paper, a model-based calibration scheme for the 7-wavelength aethalometer was developed to evaluate the filter loading effect caused by aerosol light absorption, and the model is tested against ambient measurements and is found to require coefficients that are situation specific.
