The European Solar Orbiter project has taken another step towards launch-readiness, with Australia's CSIRO delivering the last of the optical filters that the orbiter needs to image the sun. The spacecraft is due to launch in 2017, and will adopt an orbital distance similar to that of Mercury, which is closer than other …
Er... nope. Solar irradiation is a major factor for several reasons, including generation of atmospheric water vapour, which is a greenhouse gas. So is methane, which is about 20 times more efficient than CO2 as a greenhouse gas.
Mind you, the quote from the article was not about global warming models, but about climate models. I.e., what they use to make long-term weather forecasts, among other things.
"If the accuracy is 1/30th, why give us the wavelength down to 1/10000th?"
Simple. That is the nominal wavelength the filter was designed for. The accuracy is + or - one thirtieth nanometer. So, we have a theoretical value for what we're shooting at, and the accuracy is, as said, plus or minus one thirtieth nm. Meaning that while the design value is accurate down to 1/10000th, the actual value achieved may be anywhere near there within plus or minus those 1/30th nm.
