Remarkable Surface Synoptic Maps from the 1930s
A set of high-resolution maps depicting the temperature, wind, cloud, and precipitation (2.5 previous hours) have been digitized and reproduced for 1500 LT 12 October 1937 for an area in eastern Ohio. These are only one time sample of map sequences that exist. They are an almost unmined source for research into mesoscale surface weather changes and associated hydrologic phenomena
