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 πŸ”₯ 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 NiΓ±o 2015/6 shows how the atmosphere can be affected if warmer and drier conditions are more prevalent in the future.
