Mathematical Computation of Insolation

Abstract

The explanation of tables and figures.
Tables 1 to 6 contain the necessary coefficients for the computation of insolation by the method of expansion for any long period and the results of computation by this method for summer half, winter half and total year. By such method as explained in Part I etc. we have obtained the daily amount as shown in tables 7 and 8, and the half and total yearly as shown in tables 9 and 10. There exists a satisfactory coincidence between both methods concerning the half and total year.
Tables 7 and 8 are shown graphically in Figs. 1-6, in relation to the longitude of the sun, taking the earth's latitude as parameter. These are the annual variations of the amounts. Tables 9-10 are shown in Figs. 7-10 in relation to the latitude. Results concerning to planes are here omitted because they shall be given in the next paper on the insolation on the inclined plane.
