Natural water bodies contain many impurities and may be most reflective for green light, but their reflectance is generally higher at visible than at near-infrared wavelengths. 2a) Venus and Mars orbit the Sun at average distance of 0.72AU and 1.52 AU, respectively.

Since that time, all modernizing economies have been consuming increasing shares of their fossil fuels indirectly as electricity and introducing new modes of primary electricity generation––nuclear fission starting in the mid-1950s, and later also wind turbines and photovoltaic cells––to boost the overall output of this most flexible and most convenient form of energy. It only takes a minute to sign up.Considering that the Solar Flux on top of Mars' atmosphere is 590 W/m2 (following the 1/r^2 relation for sunlight), how much of this incident light actually arrives to Mars.In other words, what is the value of the Solar Flux on Mars surface after it has been attenuated by the thin atmosphere of the planet? 3 0 obj

Solar flux just outside the Earth's atmosphere is referred to as the ‘solar constant’ and has a value of approximately 1373 W m −2.Reflectance, scattering, and absorption of light in the atmosphere can reduce this amount by 15–80% before reaching the Earth's surface. Anybody can answer
That transition is yet to run its course in most low-income economies, particularly in Africa.

A solar flare is a sudden flash of increased brightness on the Sun, usually observed near its surface and in close proximity to a sunspot group. Water vapor and carbon dioxide strongly absorb some specific bands of infrared radiation and are significant as ‘greenhouse’ gases. >> stream Anybody can ask a question
What they found was that a dipole field positioned at Mars L1 Lagrange Point would be able to counteract solar wind, such that Mars' atmosphere would achieve a … The f-Chart method can be used for estimating the fraction of the load that will be met by the solar thermal system. As a result, solar rays come as close as 124 miles to the Earth's surface. >> It is common to utilize the 10.7 cm radio flux (desig-nated F10.7) as a proxy for EUV, as both emissions are thought to …

/PageMode /UseThumbs There are a lot of helpful tables in the linked NASA paper.Thanks for contributing an answer to Space Exploration Stack Exchange! According to this map, the best areas are near the equator in Chile and slightly north of the equator in Chad/Libya/Sudan, which produce around $2800 kWh/m^2$ per year - roughly $320 W/m^2$.
/Length 3249 Looking with regards to an optimized system for a long-term colony. Earth's only natural satellite is simply called "the Moon" because people didn't know other moons existed until Galileo Galilei discovered four moons orbiting Jupiter in 1610. The Earth is a distance d = 1.5 x 1011 m from the Sun.At that distance, the solar radiation flux F s is distributed uniformly over a sphere centered on the Sun with radius d. What is the solar radiation flux F s in W m-2?
The second key attribute of this transition has been a steady relative retreat of coal mirrored by the rise of hydrocarbons, first crude oil and later natural gas.Improving the quality of life has been the principal individual benefit of this quest for higher energy use that has brought increased food harvests, greater accumulation of personal possessions, abundance of educational and leisure opportunities, and vastly enhanced personal mobility. Temperatures on the Martian equator vary significantly - around $25 ^oC$ at noon, and around $-60 ^oC$ at night (I have no idea how this varies with Mars' orbit, so take that as you wish). Can you edit your question to make it clear there?
5. Any important clarification or change should be made in the question itself, where it will continue to be seen.Can you add some sources/calculation to back up the estimate of Mars irradiance being 590W/m2?
