Total solar irradiance was observed simultaneously outside the earth's atmosphere by three types of absolute cavity radiometers and duplicates of four of the Nimbus 6 Earth Radiation Budget (ERB) solar channels in a June 1976 Sounding Rocket Experiment. The preliminary average solar constant result from the cavity radiometers is 1367 W m(-2) with an uncertainty of less than +/-0.5% in SI units. The duplicate ERB channel 3 on the rocket gave a value of 1389 W mm(-2) which agreed exactly with the Nimbus 6 ERB channel 3 measurement made simultaneously with the rocket flight. Therefore, Nimbus 6 ERB solar constant values should be reduced approximately 1.6% in order to convert the values to SI units.
1976年6月的一次探空火箭实验中，利用三种绝对腔式辐射计以及四台Nimbus 6地球辐射收支（ERB）太阳通道的复制品，在地球大气层外同时观测了总太阳辐照度。腔式辐射计得出的太阳常数初步平均值为1367 W m(-2)，国际单位制下的不确定度小于±0.5%。火箭上的ERB通道3复制品给出的值为1389 W mm(-2)，与火箭飞行时同时进行的Nimbus 6 ERB通道3测量结果完全一致。因此，为了将Nimbus 6 ERB太阳常数的值转换为国际单位制，应将其值降低约1.6%。
