The last set of maps is methodological in character: these maps are devoted to the differences in quantity estimates resulting from the use of different methods. The data of about 4000 meteorological stations were subjected to treatment by three semi-empirical methods, namely those of F. Albrecht, M.I. Budyko and H.L. Penman. Albrecht was a German heat-balance climatologist of some originality who died in 1965. All maps showing "plain" results are based on Albrecht's procedure.
A discussion of all three methods with their respective modifications is given in some detail in the leading section of the text before the maps. The middle section is devoted to explaining the main features of the maps. Finally, the area averages derived from the station-by-station results are presented in tables in the last section.
Area-averaging was done by five-degree latitude belts as well as by continents. Accordingly, area means are specified for various combinations of continents and latitude belts. Also, a month-by-month global heat balance is given derived from the results of the present investigation and from estimates for the oceans carried out by Albrecht in the early 1060s.
Of interest to all geophysicists, meteorologists, geographers, ecologists, their institutes and organizations, scientific libraries.
