InMAP Grid

This is a variable sized grid outputted from the Intervention Model for Air Pollution (InMAP) model. Smaller grid cells are used for more densely populated locations. This grid covers the contiguous United States and is projected in Lambert Conformal Conic (LCC) coordinates.本数据集为空气污染干预模型（Intervention Model for Air Pollution, InMAP）生成的可变尺度网格。该网格针对人口更为密集的区域采用更小的网格单元，覆盖美国本土，投影采用兰勃特等角圆锥（Lambert Conformal Conic, LCC）坐标系。
