Sentences with phrase «total solar irradiance»

A third example would be the research on how incoming solar irradiance influences China's thermometer temperature records, showing that over periods of many decades the variations in total solar irradiance in the upper atmosphere are matched by variations at the surface.

The Sun's largest influence on the Earth's surface temperature is through incoming solar radiation, also known as total solar irradiance (TSI).

Magnetic field indices derived from synoptic magnetograms of the Mt. Wilson Observatory, i.e. Magnetic Plage Strength Index (MPSI) and Mt. Wilson Sunspot Index (MWSI), are used to study the effects of surface magnetism on total solar irradiance variability during solar cycles 21, 22 and 23.

«All 18 periods of significant climate changes found during the last 7,500 years were entirely caused by corresponding quasi-bicentennial variations of [total solar irradiance] together with the subsequent feedback effects, which always control and totally determine cyclic mechanism of climatic changes from global warming to Little Ice Age.»

Willson, R.C., and A.V. Mordvinov, 2003: Secular total solar irradiance trend during solar cycles 21 - 23.

I printed off the graph of Total Solar Irradiance Data and it looks like the trough in 86 is almost identical to the trough in 96.

The reason is that in the absence of the cosmic ray effect the impact of solar is through total solar irradiance (TSI), and is very small.

-LSB-...] This is what the IPCC (the world's most authoritative body on climate change) had to say on solar forcing in its most recent report «Continuous monitoring of total solar irradiance now covers the last 28 years.

Annual Total Solar Irradiance (thin light blue) with 11 year moving average of TSI (thick dark blue).

We also demonstrate that SPM data can be employed to reconstruct total solar irradiance variations with almost the same accuracy as recently shown for MDI data.

The solar effect on climate has been discounted by the climate modellers because the variation in total solar irradiance between the peak and the trough of a single eleven year (approximately) solar cycle seems far too small to make any difference to global temperature.

«Secular Total Solar Irradiance Trend During Solar Cycles 21 - 23.»

During the solar minimum of 2008, the value of total solar irradiance at 1 AU (TSI) was more than 0.2 Wm - 2 lower than during the last minimum in 1996, indicating for the first time a directly observed long - term change.

If total solar irradiance does not seem to account for it that is no reason to ignore the phenomenon yet the modellers and the IPCC do so.

We have also been able to compute total solar irradiance since the Maunder minimum and further into the past throughout the whole Holocene.

During a dry winter, the reduction of aerosol concentrations in weekend days may overwhelmingly impact on the DTR through a direct effect, i.e. by increasing total solar irradiance near the surface and raising the daytime temperature and maximum temperature, and lowering relative humidity.

The impact of the solar cycle on precipitation in the model experiments arises from two different mechanisms, the first involving UV changes, the second total solar irradiance.

Two methods are used to determine how low total solar irradiance (TSI) fell during the Maunder Minimum.
