[…] the Smithsonian Institution of the United States sponsored the first
series of WWR, edited by H. Helm Clayton, covering the period 1800-1920, and published in a single volume of 1196
pages in 1927. The publication included, as IMCC recommended, a full period of record through 1920 of monthly
means of temperature, pressure (station and sea level) and precipitation for selected global stations. This was
reprinted by the Smithsonian („Smithsonian Miscellaneous Collections, Volume 79“) in 1944.
