Solar Eclipse over Antarctica

The moon cast a long shadow over Antarctica on November 23, 2003, in a total solar eclipse. The sun typically hangs low on the horizon during the southernmost continent''s almost-summer months, so when the Moon moved between the Sun and the Earth, its shadow fell in a roughly 500-kilometer long oval like the long shadows of a early summer dawn.

Antarctica as a Global Common Flashcards (AQA A Level

The albedo effect refers to the reflection of solar radiation by light-colored surfaces. As glaciers and ice sheets melt in Antarctica, the dark-colored ocean or land surface absorbs more of the sun''s energy, causing more warming and contributing to a positive feedback loop.

Long-Term Variations of Global Solar Radiation and

An empirical model to predict hourly global solar irradiance under all-sky conditions as a function of absorbing and scattering factors has been applied at the Dome C station in the Antarctic, using measured solar

Antarctica : Global, Environmental and Economic Issues

Antarctica is the planet''s fifth largest continent. It contains the Earth''s largest (of two) remaining ice sheets and is considered to be one of the most important scientific laboratories on Earth. Changes in the area and volume of the two polar ice sheets in Antarctica and Greenland are intricately linked to changes in global climate, and could result in sea-level changes that could

Antarctica : Global Science from a Frozen Continent

"Antarctica is the coldest and driest continent on Earth - a place for adventure and a key area for global science. Research conducted there has received increasing international attention due to concerns over destruction of the ozone layer and the problem of global warming and melting ice shelves.

6 FAQs about [Antarctica global solar world]

How does solar radiation affect Antarctica?

Front. Earth Sci., 31 August 2022 Solar radiation drives many geophysical and biological processes in Antarctica, such as sea ice melting, ice sheet mass balance, and photosynthetic processes of phytoplankton in the polar marine environment.

Can Antarctica be used to measure reflected solar radiation?

Use of Antarctica for validating reflected solar radiation measured by satellite sensors. J. Geophys. Res. 113, D16S34. doi:10.1029/2007JD008835 Karlsson, K.-G., Anttila, K., Trentmann, J., Stengel, M., Fokke Meirink, J., Devasthale, A., et al. (2017).

What is the average air temperature in Antarctica?

The annual averages were 316.49 Wm −2 for the calculated global solar radiation, 0.332 for S/G, −46.23 °C for the air temperature and 0.10 hPa for the water vapor pressure.

Which weather stations provide the most accurate surface radiation balance in Antarctica?

To our best knowledge, ground-based solar radiation at automatic weather stations and yearly-round stations remain the primary source for providing the most accurate data and monitoring surface radiation balance in Antarctica (Stanhill and Cohen, 1997; Braun and Hock, 2004).
