U.S. AFGWC Northern Hemisphere Dew Point and Cloud Analyses

This dataset contains daily grids of dew point depression and cloud coverage for the period September 1963 to April 1972, provided by the U.S. Air Force Global Weather Central (AFGWC). Grids are available twice-daily at 12-hour intervals (00Z and 12Z). Dew point depression is available at four levels (850mb, 700mb, 500mb, and 400mb), as are low, middle, high, and total cloud coverage.

本数据集收录了美国空军全球气候中心（AFGWC）提供的1963年9月至1972年4月期间每日露点压降和云覆盖度的网格数据。网格数据以12小时为间隔，每日提供两次（00时和12时）。露点压降数据分别对应850百帕、700百帕、500百帕和400百帕四个高度层，同时提供低空、中空、高空及总云覆盖度数据。
