glory.gsfc.nasa.gov/overview-tsi.htmlThe total solar irradiance (TSI) is the amount of solar radiative energy impinging on the Earth's upper atmosphere. As can be seen on Figure 1 below, the TSI is observed to vary in time on a variety of timescales, including a prominent variation in phase with the solar magnetic activity cycle, with yearly averages going from 1365.5 Watt per square meter at solar minimum, up to of 1366.6 at maximum. Superposed on this slow trend are fluctuations about the means of about +/- 1 Watt per square meter on timescales of a few days. Interestingly, the Sun is slightly brighter at solar maximum, even though sunspots are darker than the rest of the solar photosphere. This is because at solar maximum, a great many magnetized structures other than sunspots appear on the solar surface and many of them, such as faculae and active elements of the network, are brighter than the photosphere. They collectively end up slightly overcompensating for the overall irradiance deficit associated with the larger but less numerous sunspots.

And, as was I believe pointed out in the previous reference (Haigh), the effect of a watt in the Ultra-violet portion of the spectrum may not have the same 'climate affect' as one in the infra red portion of the spectrum. Thus the spectral shift documented in the 2004-07 time period (on the descending limb of solar cycle 23) may have produced effects that have not been quantified. The author did note that this appears to be a change to what occurred on the descending limb of solar cycle 22. I have noted there is a downward shift in Arctic ice extent and an upward shift in N. Hemisphere snow fall that occurs in the same time period. Doesn't mean they are related ... but it is interesting. The ice-extent drop is superimposed on a longer-term decline and is followed by what might be a plateau ... or the base of a change in slope. Comments?

The variation of the light bands in TSI have been poo pawed by climate scientists. The sad thing is, they really don't know squat!
As more is being discovered, it appears that there is a link between conditions on earth and the variation. Can I say for certain? Nope, but I am really interested in learning more.
ARGO data is showing a decline in ocean temps. Is that decline related to variations in TSI bands? I don't know.
What I do know is that climate CAN change in a heartbeat and there HAS to be a cause for that change. It is WELL documented in the paleo field. Climate scientists continue to say it is impossible. Sorry, observations beat speculation any day of the week.
I like your charts Missouriboy. I wish we had a longer chart.

www.sciencedirect.com/science/article/pii/S1364682616301092?dgcid=raven_sd_via_emailAbstract We compare here the effect of geomagnetic activity (using the aa index) and sunspot activity on surface climate using sea level pressure dataset from Hadley centre during northern winter. Previous studies using the multiple linear regression method have been limited to using sunspots as a solar activity predictor. Sunspots and total solar irradiance indicate a robust positive influence around the Aleutian Low. This is valid up to a lag of one year. However, geomagnetic activity yields a positive NAM pattern at high to polar latitudes and a positive signal around Azores High pressure region. Interestingly, while there is a positive signal around Azores High for a 2-year lag in sunspots, the strongest signal in this region is found for aa index at 1-year lag. There is also a weak but significant negative signature present around central Pacific for both sunspots and aa index. The combined influence of geomagnetic activity and Quasi Biannual Oscillation (QBO 30 hPa) produces a particularly strong response at mid to polar latitudes, much stronger than the combined influence of sunspots and QBO, which was mostly studied in previous studies so far. This signal is robust and insensitive to the selected time period during the last century. Our results provide a useful way for improving the prediction of winter weather at middle to high latitudes of the northern hemisphere.

WELCOME to my world! This type of interruption will only continue to get worse. I hate to be the bearer of bad news, but the fluctuations on the grid that solar/wind cause tax the living daylights out of transformers etc. The last wind spike here caused an expenditure of over 3K to replace all the burnt out stuff. The co-op payed a little, the rest out of pocket. I have now surge protectors on virtually everything, and am looking at putting one on the whole farm. That surge blew 5 large transformers as well. Damnest thing.....it really is!

Damnest thing.....it really is! I have a whole house surge protector then surge protectors and battery back up on all inside devices. Still managed to lose some external electrics with a lighting strike 15 feet from the house.

A lightning strike is one thing. The steady surges, while not like a lightning strike, are another. It gets old having to replace electronics that have not lived out their useful life. Small things you deal with, but 10HP and larger motors are another. They are not light, nor easy to replace. And when you NEED that higher horsepower is when you REALLY need it.
A full grain leg grinding to a halt is not fun.
