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 percent per year, a leveling off near solar minimum and an increasing irradiance for the beginning of cycle 22. Through April 1988, the irradiance has increased about 0.06 percent above the minimum value which was about 0.08 percent below the highest values obtained near solar maximum. The rise appears more rapid than the decline.
