CHRISTIAN SCIENCE MONITOR.

MOODS of the sun are responsible for our weather, good or bad, hot or cold. Earth's atmosphere changes

only with the changes that take place in the radiation from the centre of the solar system. Tnerefore, in the opinion of Dr. Charles G. Abbot, of the Smithsonian Institution, Washington, scientific means of measuring the heat of the sun, now being perfected, will go a long way toward making long-range weather forecasting more accurate.

In any event, says the Christian Science Monitor, it is recognized that an essential element, new to weather forecasting, has been discovered and proved; its application is a matter of research and time. Continuing, the Monitor quotes the following from a recent statement issued by the Smithsonian Institution:—

“For 30 years Dr. Abbot has been investigating the sun and measuring the heat it sends to the earth. In 1903 he surmised the amount of that heat varied. Urged by that clue and its great significance to mankind if true, he has spent the intervening years in elaborate measurements of solar radiation in many parts of the world: at Mount Wilson and Mount Whitney, Calif.; at Bassour, Algeria; at Mount Harqua Hala, Ariz., and Mount Montezuma in the nitrate desert of Chile “He developed instruments capable of measuring a millionth of a degree change in temperature and other instruments of the greatest complexity and usefulness to be used in connection with his measuring

instruments for standardizing and for computing results.

“The outcome of all this work was to justify his belief in the truth of his theory. But some of the most prominent weather men in the world disagreed with Dr. Abbot. They did not doubt that weather would change if the sun’s heat varied, but they were not convinced by Dr. Abbot’s work that the sun’s heat does vary. The proof which Dr. Abbott now announces appears finally to refute these criticisms, and leaves no further doubt of the variability of solar radiation.

“The essence of this proof lies in a comparison of measurements of solar radiation made at times when the atmosphere is practically identically the same. It is obvious that if the atmosphere is the same and the instruments are correct any changes must mean differences in the amount of heat given off by the sun.

“With the great step accomplished the next move is to make the daily measurements of solar radiation as accurate as is humanly possible. To help accomplish this, the National Geographic Society has given $55,000 to establish a solar observatory at Mount Brukkaros in Southwest Africa to co-operate with Dr. Abbot’s two existing stations in California and Chile.

“To insure that at least one accurate measurement be made for every day in the year, a fourth station is needed in the northern section of the Eastern Hemisphere. To establish this the Smithsonian Institution must have funds.”
