Extraterrestrial solar irradiance measurements from the Nimbus 6 satellite
Abstract
Solar irradiance measurements both total and in spectral subdivisions have been accomplished for more than one year. The total solar irradiance had a value of 1392 W/sq m shortly after launch. This was higher than the value of 1370 W/sq m which was expected by approximately 1.6%. A recent rocket flight employing a matching sensor as well as three types of absolute radiometers gave results showing the true value to be closer to 1370 W/sq m. The spectral values obtained show a better agreement with values of Labs and Neckel (1973) than with other solar curves. No definite relationship variation with solar activity has been established as yet. The period was characteristic of a very quiet sun.
