——欲睹大尺度开放“地球素颜照”,请点击附4,并可下载日本高清版
——附4中的鸭蛋形地球是将原始网页直接复制粘贴的变形,非真容也
看到网络正热议地球素颜照,赵斌博友也发表了《又一个有关地球素颜照的乌龙:辟谣一则新闻的说法》。由于现代千里眼——遥感技术发展迅猛,我虽置身遥感环境却所知有限。
不过,各种网络来源都未提供传闻源头的《每日邮报》的原始链接。我搜索之下,有些惊讶,报道这则消息的记者撰写了很多科学报道。如果此报道失实,那么是他本人判断失误、对科学成果作了误读,还是科学工作者直接向他提供了此种说法?
似为《每日邮报》科学名记的 Jonathan O'Callaghan撰写了诸多科学报道。如果“地球素颜照”的报道失实,那么,他的其他报道有多少属于失实。英国本土是否已经发现他的失误?
标题中所谓“大尺度”是表示国内媒体的图像明显小于《每日邮报》原图。不过,我将《每日邮报》原始页面直接复制、粘贴后,附4出现的效果已是鸭蛋形。请前往附4原始网址观赏大尺度“地球素颜照”。所谓“开放”照,是指日本提供免费自由下载、人人可以饱览真容。
我建议赵斌博友与《每日邮报》进行联络,提出自己的见解。如果确实错误,对其他国家读者也是一个福音。
此外,即使不是《每日邮报》所称的“地球素颜”或“真彩色”卫星影像,它的科学性与观赏性还是很强的。
注:附4中提供的日本网址(http://www.jma.go.jp/jma/jma-eng/satellite/news/himawari89/20141218_himawari8_first_images.html)我的联通宽带总是链接失败。如有热心博友能够链接,可下载后提供分享,以使有兴欣赏高清大图者一饱眼福。

又一个有关地球素颜照的乌龙:辟谣一则新闻的说法(赵斌)
The GREY planet:
True-colour image reveals what Earth REALLY looks like without any filters or editing
An image taken by a Japanese satellite launch on 7 October 2014 has snapped the true colour of planet Earth。
Taken in multiple wavelength bands, the image from the Himawari-8 weather satellite shows Earth's natural colour
To the human eye the planet would appear differently, but this is what it looks like without image enhancement
Himawari-8 took the image from geostationary orbit 22,240 miles (35,790km) away from the planet
The satellite will be used with a twin, Himawari-9, to provide continuous observation of the East Asia region.
From a distance of 22,240 miles (35,790km), the satellite shows what our planet looks like before any filters or image enhancements are made to the shot.
And the incredibly high resolution image also highlights stunning details on Earth including clouds, oceans and Australia’s vast desert.
Scroll down for video
The Japan Meteorological Agency's Himawari-8 satellite has returned its first true colour image of Earth, seen here. It wascaptured using all 16 image bands from the satellite. Testing of Himawari-8's systems, including related ground facilities, are reportedly going well
The image was taken by Japan’s Himawari-8 weather satellite, which launched on 7 October 2014 and is said to be the first true-colour image returned by the satellite to Earth.
A huge 11,000 by 11,000 pixel version is available on the Japan Meteorological Agency's (JMA) website, although the makes advise downloading the file, rather than view it in a browser, because the image can take a long time to load.
The satellite was placed in a geostationary orbit above Earth, which means it stays above the same portion of the planet - in this case Australia, Japan and the other regions seen.
The instrument used to take the image was the Advanced Himawari Imager (AHI) on the spacecraft.
Himawari-8 is actually one of two twin satellites that will be used to provide continuous observation of the East Asia and Western Pacific regions. The next satellite, called Himawari-9, will launch in 2016.
The use of the words ‘true colour’ is a little bit of a misnomer, as this is not exactly what the planet would look like to the human eye.
Most images we see of Earth are colour-corrected to show how humans would see them. This image, however, was taken in multiple bands and shows the natural appearance of Earth from space.
The image is said to be 'true colour' as it shows what the planet would look like from space without a human eye. However, to us the planet appears slightly more blue and colourful. By brightening the picture, shown, more detail and features can be revealed
The stunning 11,000 x 11,000 pixel shot reveals a huge amount of detail. Here can be seen the north coast of Australia, with the sun's light glinting in the Arafura Sea, while wisps of clouds can also be seen at the bottom of the image
In the centre of the image, the sun’s glint reflecting off the ocean, just north of Australia, can be seen.
Further north, partially covered by clouds, is Japan and the rest of East Asia.
To the right is the vast Pacific Ocean, perhaps highlighting one of the most striking things about the image; namely, how much of our planet is covered by water.
Earth’s surface is 71 per cent water, with the other 29 per cent being the continents and islands.
A whopping 96.5 per cent of this water is contained in the ocean as salt water, with the remaining 3.5 per cent being freshwater lakes and ice.
But despite covering the vast majority of the surface, water accounts for just 0.02 per cent of our planet’s mass as, relative to the planet itself, the oceans are not very deep.
Where exactly all this water came from has been a cause of much debate in recent years.
As Earth was scorchingly hot early in its life, it’s widely believed that water was brought to Earth by space rocks: asteroids or comets.
A few weeks ago, however, results from Esa’s Rosetta mission indicated that the water contained on the comet it is orbiting, 67P, differs from that on Earth.
This supports the theory that water was brought to Earth by asteroids, not comets - although scientists note that further findings and studies will be needed to confirm the theory.
Himawari-8, illustration shown, is actually one of two twin satellites that will be used to provide continuous observation of the East Asia and Western Pacific regions. The next satellite, Himawari-9, will launch in 2016
Other images of Earth, such as Nasa's famous Blue Marble images (Western Hemisphere shown), use image enhancement and colour correction to show what the planet would look like to the human eye from space
