TOTAL SOLAR AND SKY RADIATION ON MOUNT WASHINGTON, N. H.

Solar radiation during a total solar eclipse

Modeling Total Solar Irradiance Variations Using Automated Classification Software On Mount Wilson Data Solar Physics

We present the results using the AutoClass analysis application available at NASA/Ames Intelligent Systems Div. (2002) which is a Bayesian, finite mixture model classification system developed by Cheeseman and Stutz (1996) . We apply this system to Mount Wilson Solar Observatory (MWO) intensity and magnetogram images and classify individual pixels on the solar surface to calculate daily indices...

Ecological Zones: A Hike Up Mount Washington

Spatiotemporal change of sky polarization during the total solar eclipse on 29 March 2006 in Turkey: polarization patterns of the eclipsed sky observed by full-sky imaging polarimetry.

Using 180 degrees field-of-view (full-sky) imaging polarimetry, we measured the spatiotemporal change of the polarization of skylight during the total solar eclipse on 29 March 2006 in Turkey. We present our observations here on the temporal variation of the celestial patterns of the degree p and angle alpha of linear polarization of the eclipsed sky measured in the red (650 nm), green (550 nm)...

More frequent cloud-free sky and less surface solar radiation in China

[1] Newly available data from extended weather stations and time period reveal that much of China has experienced significant decreases in cloud cover over the last half of the Twentieth century. This conclusion is supported by the analysis of the more reliably observed frequency of cloudfree sky and overcast sky. The total cloud cover and low cloud cover have decreased 0.88% and 0.33% per deca...
