This post is an update. It reports 3 more months
of irradiance data than the last edition. These newer data did not change any major conclusions in this analysis. -.-. --.- Roger =-=-=-=-=-=-= New Data Show Solar Irradiance Continuing to Slowly Fall By Roger Coppock 02/08 ABSTRACT: An analysis of newly available satellite Solar irradiance measurements from 1976 to 2008 shows a small but statistically significant decrease of -0.0066 +- 0.0005 Watts per square meter per year over the 32-year period. PROCEDURE AND RESULTS: The location of the data's end points within the Solar cycle biases a simple linear regression and produces an incorrect result. (Roughly twice the correct magnitude, or -0.0118 +- 0.0006 W/m^2 per year.) Therefore, the analysis required a non-linear curve fit to a 'line plus sine' expression: B1 + B2*Year + B3*SIN(B4+(Year*2Pi)/B5) where the determined coefficients B1, B2, B3, B4, and B5 are known as the intercept, slope, amplitude, phase, and period respectively. After correcting for the appropriate cycle of the SIN() function, (B30.0 and 2*PiB4=0.0), the results of the 10725-point curve fit are as follows: Irad ~ beta1 + beta2 * Year + beta3 * sin(beta4 + (Year * 2*Pi)/beta5) Parameters: Estimate Std. Error t value Pr(|t|) beta1 1.379e+03 9.511e-01 1450.132 2e-16 beta2 -6.647e-03 4.772e-04 -13.930 2e-16 beta3 4.974e-01 5.908e-03 84.195 2e-16 beta4 1.148e-01 2.746e+00 0.042 0.967 beta5 1.015e+01 2.258e-02 449.405 2e-16 Residual standard error: 0.4324 on 10720 degrees of freedom Please note the large standard error on beta4, the phase of the SIN function. Only three cycles of high variance data produce this. As an exercise, try to locate the peeks and valleys of these data in this graph. Please see: http://members.cox.net/rcoppock/Solrad.jpg The data are black. The linear component, both intercept and slope, is green. The total 'line plus sine' function is red. The curve fit was performed by the "R" statistical package for Power PC OSX, Version 2.2.1. The dual cavity radiometer Solar irradiance data come from PMODWRC. They cover the period from 1/12/1976 to 01/03/2008. http://www.pmodwrc.ch/pmod.php?topic.../SolarConstant ftp://ftp.pmodwrc.ch/pub/data/irradi...41_61_0801.dat A preprocessing program converted month and day information into fractional years and removed data marked by PMODWRC as invalid. DISCUSSION: Global warming 'skeptics' often claim that increases in Solar radiation reaching the top of Earth's atmosphere, not rising CO2 concentrations in the atmosphere, are responsible for the observed climb of the global mean near surface temperatures in the last thirty years. This argument was not supported by the facts. Now it is even less so. When the solar cycle was statistically removed, prior data showed no significant long term change in Solar irradiance large enough to explain the warming, (about 3 W/m^2 over the last two centuries are needed.) Present data actually show a very small but statistically significant decrease in solar output over the last three solar cycles. It is very hard to support any claim of a solar cause for global warming when measurements clearly show decreasing solar output.
