Short summary
The paper presents results of a Brewer MKIV optical depth measurements from 1994 to 2016. The optical depth values were determined for the wavelengths of 306.3, 310, 313.5, 316.8 and 320 nm. The Langley plot method was applied to calculate the aerosols optical depth. A statistically significant decrease in the total optical depth of the atmosphere was observed with all examined wavelengths. Its root cause is the statistically significant decline in the optical depth of aerosols.
