Atmospheric river dust scores for 2001 to 2018

The AR "dust score" characterizes the dustiness of the environment associated with ARs that made landfall along the west coast of the U.S. between 2001 and 2018 using satellite-based observations. The AR dust score is calculated from the average of dust aerosol optical depth within the horizontal boundaries of the landfalling AR, as defined by the Rutz AR catalogue. This dataset has been used to investigate how often dust is present in the surroundings of ARs along the U.S. west coast, as dust can impact cloud microphysics and precipitation from these storms. Further information describing the calculation of an AR dust score can be found in Voss et al. (2020) (doi:10.1175/JCLI-D-20-0059.1).大气河流（Atmospheric River，以下简称AR）粉尘评分依托卫星观测数据，用于表征2001年至2018年间在美国西海岸登陆的AR所关联的环境粉尘状况。该评分的计算依据为Rutz AR目录所定义的登陆AR水平边界内的粉尘气溶胶光学厚度平均值。本数据集已被用于探究美国西海岸AR周边环境的粉尘出现频率，因为粉尘会影响这类风暴的云微物理过程与降水。有关AR粉尘评分计算方法的更多细节，可参阅Voss等人2020年发表的研究（DOI: 10.1175/JCLI-D-20-0059.1）。
