SOLAR OBSERVATIONS.
SOLAR AND SKY RADIATION MEASUREMENTS DURING APRIL, 1923.
By HERBERT H. KIMBALL, In t.'harpe, Solar Radiation Investigations.
For a descri tion of instruments and exposures, nncl
measurements, the reader is rcferred bo this REVIEW for
April, 1930, 48:335, and a not,e in t,he REVIEW for No- vember, 1932, 50:595.
From Table 1 it is seen that, direct solar-radiat.ion in- tensities averawed sli htly below the normal values for April at Lincopn, Nefr., and close t,o normal nt Rash-
ington, D. C., and Madison, Wis.
an account of t R e niethod of obtaining and reducing t,he
Table 2 shows for all three stations only unim ortant depnrtures from the average total amount of so P ar and sky rncliation received on a horizontal surface during April. Sk~-li~lit-pc,l~~~izntioii nieasurements obtained at Wash- inpt.on on 12 (lays, give a nienn of 52 per cent, with a
niasirnum of 64 per cent on the 34th. At Madison, nica.surenient.s obhinecl on four days during the last half of the niont,li give n niean of 5s er cent, with
a. mnximum of 65 per cent on t,he 1st R . These are slight,ly hclow avernge vdues for April at the respective stations.
