CLIMATOLOGICAL SERVICE MEMORANDUM
Climatological Service Memorandum 1948 - 1965
Starting in 1948, Helmut Landsberg (director of the Environmental Data Service [1954-1966] at the U.S. Weather Bureau) started issuing a set of informative memorandum that would continue for the next 17 years. "It has been our policy to use the Climatological Service Memoranda as means of interchange of ideas, plans and completed projects" - Landsberg 1955
Below are the pdf's of each of the 109 memorandum. They are very informative and you will notice that often today we face similar challenges that were address during this period.
