NO. I ASTROPHYSICAL OBSERVATORY, 1 895 TO 1 955 — ABBOT 



31. Campaign of observations of solar 

 intensity on surfaces of different 

 orientations and with various 

 spectral regions, made at army 

 camps for Quartermaster Corps, 

 for a period of 8 years. 



22. Daily solar-constant values, 1920- 

 1952, with 1 0-day and monthly 

 means. 



2Z. Convenient table for solar-constant 

 tabulations. lo-day and monthly 

 mean excesses over 1.900 in 

 hundredths percentages of 1.94. 

 Thus 1.950 becomes 



I.950-I-900X 100 = 2.58. 

 1.94 



Similarly 1.940 becomes 2.06. 

 This difference, 0.52, is 0.53 per- 

 cent of mean solar constant.

 point for economy, and do not
