This time we will present a comparison of different soot generators, which are potential candidates to be a used as a standard reference material for light absorption measurements.

Soot generator comparison experiment ongoing. We have tested diffusion and premixed flame ๐Ÿ”ฅ burners. We will continue experiments next week testing an inverted flame generator and two spark generators.

Next week we will start a workshop to test different aerosol generators. The goal is to find a suitable primary standard for atmospheric black carbon absorption measurements.

The significant increase of black and brown carbon during El Niรฑo 2015/6 shows how the atmosphere can be affected if warmer and drier conditions are more prevalent in the future.
