= _ ws NY SEic Project 5.7 - Therma) Flux and Albedo Messurements from Alroraft Capt R. L. Dresser The objective of Project 5.7 participation on this shot was to vbtain thermal flux and albedo information of a nuclear detonation vith airborne calorineters, radiometers, and sixteen millimeter motion picture caseras. DS Instrumentation vithia the province of Project 5.7 vhich ves instelled a iz the B47 included 19 ERDL calcrinsters and two NRDL radiometers fer seasur~ ing the direst and surfece reflected thermal redistion. Six additional caleriseters were utilised to measure thermal rediation vhied ves back eoattered tovard the evekpit. Seven GSAP B-9 cameras vere utilised to obtains photogrephie oeverage of the fireball, the earth's surface, and of clouds beneath the eirereft, and alao of any reflecting surface such as « eloud vhich sould ecutritute to the beck-vea: tered radiation, Project 5.7 instrumentation on the B-52 included the 2) basic iastrusents for thermal radiation measurements, but only an additions] two instrumate were utilised for backscatter measurements. Eight GGAP cageres vere utilised for photographie soverege. Project 5.7 instrumentation on the B.$7 consisted of the basic 2) inetrupests and aix easeras, Project 5.7 instrumentation on the B66 consisted of the beaie 21 instruments end 12 cameras.
