Abstract : This report contains an analyzed sample of attenuation measurements of blue, green, red and infrared light made in the Florida Everglades in the summer quarter of 1964. Data for the other three seasons will be included in the final report. Graphs are presented for: total transmittance versus range, direct transmittance versus range, and the ratio of indirect to direct light intensity versus the direct extinction coefficient times range. A portion of the report describes the field site, equipment used, and methods of data collection. Several auxiliary graphs give results of Polar Nepholometer measurements of the light scattered from particles in a small volume of air as a function of the angle of incidence and reflection.
