Argonne 0.2-Degree Land Use and Deposition Data

This dataset contains land use classification data on a 1/6 degree by 1/4 degree grid covering the United States from 52W longitude to 134W and from 24N latitude to 54N. Also included is a dry deposition model that uses the land use classification (and other user-supplied meteorological parameters) to compute the deposition velocities of sulfur dioxide (SO2) and sulfate (SO4) pollutants.

本数据集包含覆盖美国（经度范围为西经52°至西经134°，纬度范围为北纬24°至北纬54°）的1/6°×1/4°网格土地利用分类数据。此外，本数据集还附带一套干沉降（dry deposition）模型，该模型可基于土地利用分类结果及其他用户提供的气象参数，计算二氧化硫（sulfur dioxide, SO2）与硫酸盐（sulfate, SO4）污染物的沉降速率。
