An aerosol closure experiment might look like this: Individual aerosol particles are sampled, and their size and shape is determined under an electron microscope; A lidar emits a laser beam into the aerosol plume and detects the backscatter signal; An aerosol flow is led through optical detectors that record the size distribution of the particles; the sunlight attenuated by the aerosol is measured by a sun photometer, yielding the optical depth of the aerosol layer; the spectral absorption of sunlight, as well as the scattering properties of the aerosol are measured by spectrometers; the extent and total reflectivity of the aerosol plume is observed by a satellite radiometer.
