The particle linear depolarization ratio (PLDR) and single scattering albedo (SSA) at 1020 nm are retrieved by the AERONET (Aerosol Robotic Network) Version 3.0 level 1.5 inversion products are used to categorize different types of aerosols and investigate their temporal distribution for the atmospheric particles of Kuwait City. The results show that when PLDR increases in the atmosphere, the amount of SSA at 440, 670, 870, and 1020 nm wavelength channels and the contribution of coarse-mode particles increased. Also, the spectral behavior of SSA changes from a negative to positive slope by increasing PLDR. The highest density of aerosol incidence rate in the two-dimensional histogram diagram occurs in the range with low fine mode fraction and dust ratio. The main objective of this study is to present that the atmosphere of Kuwait City is strongly affected by pure dust (PD) and polluted dust plumes, namely, dust-dominated mixture (DDM), pollution dominated mixture (PDM), all with an occurrence frequency of 85%. The annual average incidence rate of different aerosol types is 32.2% for DDM, 31% for PD, 21.8% for PDM, 10.3% for SA, 2.5% for MA, 1.3% for WA, and 0.9% for NA, from 2006 to 2019. However, the distribution of different types of pollution particles varies with the seasons change. The incidence rate of pure and polluted dust is more than 85% from March to October. In addition, the annual average incidence rate of dust-free pollution aerosols (NA, WA, MA, and SA) is 15%. The highest amount of dust-free pollution particles in different months is related to the SA that constitutes about 40% in the cold months.

AERONET（气溶胶机器人网络）版本 3.0 1.5 级反演产品在 1020 nm 处检索粒子线性去极化比 (PLDR) 和单次散射反照率 (SSA) 用于对不同类型的气溶胶进行分类并研究它们在大气中的时间分布科威特城的颗粒。结果表明，当大气中 PLDR 增加时，440、670、870 和 1020 nm 波长通道的 SSA 量和粗模式粒子的贡献增加。此外，通过增加 PLDR，SSA 的频谱行为从负斜率变为正斜率。二维直方图中气溶胶入射率的最高密度出现在细模分数和灰尘比低的范围内。本研究的主要目的是展示科威特市的大气受到纯尘（PD）和污染尘羽的强烈影响，即以尘为主的混合物（DDM），以污染为主的混合物（PDM），所有这些都发生85%的频率。从2006年到2019年，不同气溶胶类型的年平均发病率为DDM 32.2%、PD 31%、PDM 21.8%、SA 10.3%、MA 2.5%、WA 1.3%、NA 0.9%但是，不同类型污染颗粒的分布随着季节的变化而变化。3-10月纯粉尘和污染粉尘的发生率在85%以上。此外，无尘污染气溶胶（NA、WA、MA、SA）年平均发病率为15%。
