Xormal-incidence solar radiation va1ur.s were mcasurcd during the IGY at the South Pole:md Little America (Antarctica), at hlauna Loa (Hawaii), Tucson (Arizona), and Blue Hill Observatory (Massachusetts); some results are given in tables and graphs. Essential diffcrc,nccs among them are discusscd. The radiation data at Tucson and Blue Hill are appreciably lower than at the other stations. The radiation, corrected for solar distance, is similar at the Antarctic stations to the radiation mc:tsured at 32la1111a Loa. However, t,he actual measured values in summer are highcr at the South Pol(, than at Mauna Loa, because the sun is clowr to the earth in the Southern Hemisphere summer. The “extrapolated turbidity fxtor ” is over 2.5 at Tucson and Blue Hill, but averages 2.0 or less at the other stations with the lowest va1rlc.s of about 1.5 at the South I’olv. During the Intermtional Geophysical Year 111tiny ne\v solar radiation observations were taken>it Illany- places. In particular, new stations were installed in Ar1tu1 ctiw and one was instwlletl at the AZaunri Loa Ohserwtory in Hawaii. Some of the nor~llill-incidc~ ~ soliir radiation data which have so fttr been evduated tlrc prcsc>nt!d in
