a Particle size distribution histogram (grey bars) versus the area in μm² and cumulative particle size curves after MATISS-1 (193 days of exposure (red)), MATISS-2 (354 days (blue)) and MATISS-2.5 (365 days (green)) campaigns. Each holder has its symbol. Error bars represent the standard deviation of the data. b Dot-plots showing the density values of the coarse particles measured on surfaces of 8 x 8 mm. Centerlines show mean values: 2.45 ± 0.81 for MATISS-1 (193 days), 2.01 ± 0.84 for MATISS-2 (354 days) and 0.36 ± 0.12 for MATISS-2.5 (365 days). c Mosaic of optical images recorded at low magnification displaying typical shapes of coarse particles (top and middle, scale bar is 10 μm) and macroscopic particles (area > 1500 μm², bottom, scale bar is 100 μm).
