PLOWS: Surface Weather Observation Sectors Map Imagery. Version 1.0

This data set contains maps of surface weather observations over several US sectors (Central Mississippi Valley, Central Plains, Great Lakes, Lower Mississippi Valley, Mid-Atlantic, Northern High Plains, Ohio Valley, Southeast, and Upper Mississippi Valley. The latest observation at the time the plot was generated was utilized, so the plots contain a mix of standard hourly and special observations. The maps were generated by NCAR/RAL.

本数据集包含覆盖美国多个区域的地面气象观测分布图，所涉区域包括密西西比河谷中部、中部平原、五大湖地区、下密西西比河谷、中大西洋地区、北部高平原、俄亥俄河谷、东南部及上密西西比河谷。制图时采用了生成该图表时的最新观测数据，因此生成的分布图混合了标准每小时观测与特殊观测两类数据。上述观测分布图由美国国家大气研究中心应用研究实验室（NCAR/RAL）制作。
