Post subject: | Discrepency in TSI measurements over the last 30 years |
I was looking through some of Dr. Nicola Scafetta's work while I was browsing through his Widget, and I saw that he was part of the Active Cavity Radiometer Irradiance Monitor, which monitors TSI from the ACRIM satellite. I googled it, and I found that this particular satellite showed an increase in the power of the TSI during the minimums associated with the 11 year cycles from Cycle 21 to 22. While the maximum power remained about the same, an increase in the power during the minimum could have TSI directly explain some of the warming that took place in the late-20th Century. TSI then decreased, which is where ACRIM is in agreement with PMOD, probably contributing to the standstill in temperatures over the last 11 years. http://www.acrim.com/images/earth_obs_fig26.jpg However, PMOD shows no such increase in the minimums of Cycle 21 and 22. http://www.acrim.com/images/earth_obs_fig27.jpg These discrepencies need to be resolved, before anyone can go saying that Man is responsible for most of the warming that took place over the late-20th Century, since we aren't even certain what the brightness variations in the sun were doing during this timeframe. Comments appreciated! |

You have a series of satellites with a problem in correlation between the beginning and current that may indicate something different from the other system if this system is correct. Where exactly is the skeptic view on lack of data, lack of quality data, temperature reconstuction, models based on temperature reconstruction, and the various other aspects of the science of climate change? The data from the newest sensor only shows a decrease from the last minimum ... at the point where most of the record warm global averages occurred. The entire process has a 30 year calibration range at most and the last 10 are significantly different. |

OMG!!!! "Mike's Nature Trick" was not even referenced!!!! That should be grounds for throwing all of this information away .... right? The whole selective skepticism aspect gets a bit worn after a while. http://www.fel.duke.edu/~scafetta/pdf/2008GL036307.pdf The ACRIM-gap (1989.5–1991.75) continuity dilemma for satellite TSI observations is resolved by bridging the satellite TSI monitoring gap between ACRIM1 and ACRIM2 results with TSI derived from Krivova et al.’s (2007) proxy model based on variations of the surface distribution of solar magnetic flux. ‘Mixed’ versions of ACRIM and PMOD TSI composites are constructed with their composites’ original values except for the ACRIM gap, where Krivova modeled TSI is used to connect ACRIM1 and ACRIM2 results. |

The expalnation went off into the ether and I do not have the time to redo it now. This is the data from which the different composites are created. Note the differences between ACRIM I and ACRIM II levels and the ACRIM I from the bulk of the overlapping measurments. |
