ALBEDO MEASUREMENTS OVER THE NORTHEASTERN UNITED STATES

KIRBY J. HANSON, HERBERT J. VIEBROCK
1964 Monthly Weather Review  
On September IG, 1961, Eppley pyranometers niounted in a P2V-7 aircraft were used to measure the incoming and outgoing solar radiation fluxes at 7,500, 9,500 and 25,000 ft. along flight paths between Atlantic City, N.J., and Erie, Pi&. Simultaneous photographs and radiation values were obtained on the 25,000-ft. flight. The albedo for the high-level flight varied from 0.158 for no undercast to 0.538 for a complete altocumulus undercast. Two selected observations at 1722 GYT and 1737 GMT are

A solar radiation budget is prepared for the 1737 GMT measurement using the high-level flight data and ground data from Thornthwaite Laboratories near Elmer, N.J. Albedo values are determined from this inforination for the flight level. MONTHLY WEATHER REVIEW Vol. 92, No. 5 FIGURE 2.-Continued. FIGURE 2.-Continued.
