Abstract The cavity pyrheliometer sensor aboard Nimbus 7 is now in its tenth year of operation. Results for 9 1 2 years show a decreasing trend through the end of solar cycle 21 of approximately −0.015% per year, a levelling off near solar minimum and an increasing irradiance for the beginning of cycle 22. Through April 1988 the irradiance has increased about 0.06% above the minimum value which was about 0.08% below the highest values obtained near solar maximum. The rise appears more rapid than the decline.
