 Caltech Press Release, 4/17/2001, Dr. Steve Koonin, Steven Koonin
Earthshine measurements are a useful complement to satellite observations for determining Earth's reflectance of sunlight (its albedo), an important climate parameter.
Earthshine is readily visible to the naked eye, most easily during a crescent moon.
It is significant that the earthshine data suggest that the albedo has decreased slightly during the past five years since the sun's magnetic activity has climbed from minimum to maximum during that time.

 Earthshine   (Site not responding. Last check: 2007-10-21)
Scientists studying earthshine - the amount of light reflected by the Earth - say the planet appeared to dim from 1984 to 2001 and then reversed its trend and brightened from 2001 to 2003.
Earthshine brightening the face of the moon, he noted, was first described by Leonardo da Vinci.
Regular earthshine observations began in 1997, and the researchers suggested that the changes they observed may be part of a natural variation.

This glow is called "earthshine." And scientists have been using this ghostly glimmer to measure the total amount of light reflected by our planet.
And the brightness of this part comes from light, which is reflected on the dayside of the earth and is bounced toward the moon, and bounces back toward the night side of the earth.
Now, what we see on the earthshine, over 50 years, the change is about 5.8-6 watts per meter squared, which is more than two times that, of energy that has been allowed to reach the atmosphere, and the ground, which before, at the beginning of the eighties, was actually reflected outside.

So we had this jam music that we really were excited about, especially this riff, this main riff, that is the verses for Earthshine, and I rebuilt the song vocally around that riff.

 Earthshine could shed light on global warming / Scientists use glow on moon's dark side to measure clouds
The scientists see the earthshine effect as a kind of sentinel, warning that the pace of global warming may have speeded up in recent years.
The pace of thinning speeded up during the late 1990s, according to the satellite data, and as a result, earthshine on the moon was growing fainter.
Goode's earthshine observations, which go back five years, show that the cloud cover did in fact diminish for the first few years, but then, as clouds covered the earth more widely, earthshine on the moon grew abruptly brighter - - the opposite effect from the earlier reports of a "dimming" Earth.

 Universe Today - Decreasing Earthshine Could Be Tied to Global Warming
By combining eight years of earthshine data with nearly twenty years of partially overlapping satellite cloud data, they have found a gradual decline in Earth's reflectance that became sharper in the last part of the 1990s, perhaps associated with the accelerated global warming in recent years.
The team has revived and modernized an old method of determining Earth's reflectance, or albedo, by observing earthshine, sunlight reflected by the Earth that can be seen as a ghostly glow of the moon's "dark side"-or the portion of the lunar disk not lit by the sun.
Precision earthshine observations to determine global reflectivity have been under way at BBSO since 1994, with regular observations commencing in late 1997.

 New Scientist Breaking News - 'Earthshine' fall heats global warming debate
A new study of earthshine, the sunlight reflected back onto the Moon from our planet, suggests that falling cloud cover could explain the warming of the Earth's lower atmosphere seen over the last 20 years.
They report that the brightness of earthshine decreased steadily during the period 1984 to 2000, although that trend appears to have reversed since.
But Trenberth adds that future earthshine measurements could be an "innovative" way of probing the effect of clouds on climate.

 Moonlighting in the Earthshine, Alaska Science Forum
The dim remainder of the moon is visible because it's reflecting earthshine.
Recently the earthshine work has received encouragement from another scientist who had originally set out to prove it was all, well, moonshine.
But Koonin had no doubts about his ability to construct computer models, and his models told him that earthshine was indeed a good indicator of the earth's albedo, just about as good as the satellite data.

 Earthshine   (Site not responding. Last check: 2007-10-21)
Earthshine occurs due to a double reflection of sunlight.
This means that earthshine is dimmer than moonlight because earthshine is sunlight that has been reflected twice and moonlight is sunlight that has been reflected only once (off the surface of the moon).
In addition, the reflectivity of the moon (its "albedo") is less than that of the Earth, which makes earthshine even dimmer.

As recently presented at the 199th national meeting of the American Astronomical Society in Washington, D.C., astronomers from the University of Arizona Steward Observatory and the Harvard-Smithsonian Center for Astrophysics have benchmarked earthshine.
For the first of these we made observations of the sky near the dark limb of the moon, and observed earthshine just inside the limb.
Thus, it came as a surprise to see such a sharp rise in the far-red picture of the Earth, because that portion of the spectrum is particularly tuned to land vegetation and not the roughly 83% of the sea reflection that made up the earthshine photos.

Using the Steward Observatory 2.3-metre telescope at Kitt Peak in Arizona, the researchers analysed moonlight and ‘earthshine’.
By combining the spectra of the earthshine and the sunlight reflected directly by the Moon, Woolf and colleagues produced a spectrum similar to the one that would be seen by a distant observer who could not resolve the Earth and the Moon.
They say that their study could be refined by observations of earthshine from space – which would not need to subtract the effects of the atmosphere – and longer-term studies that would account for fluctuations in the spectra.

April and May are peak times when the moon, Earth and sun are aligned just right so that sunlight reflecting off the Earth can act like a dim flashlight shining toward the moon -- in effect, providing a faint glow on what would usually be the dark part of the crescent moon.
Clouds can reflect as much as 50 percent of the incoming sunlight back into space, so this is the time of the year when the Earth is brightest to someone standing on the moon.
The best days to catch "Earthshine" are the dates in April and May one to three days past the new moon.
