Several contrails show up in this amazing video sequence of a full year of days shown simultaneously.
A History of the Sky
Wow. I’m sure there’s a pattern there but it’s just nice to look at.
Visualized statistics – you get a feeling for the actual shares of fog, rain and clear skies. This is fabulous!
Now all we need is the same thing for 1970 … :-]
The author’s (obeyken) comment on youtube says:
“The date of the first image in the top left is July 29, 2009, and the last video (lower right) is late July 2010.”
It may be of interest to crosscheck these with the satellite images of the day (http://lance-modis.eosdis.nasa.gov/imagery/subsets/?subset=AERONET_Fresno)
Another comment on youtube (by jstrummer) says:
“Interesting concept… but artist Salvatore Pecoraro did this first in 1971 in a work entitled 365 Skies where he painted a sky for for each day.
I have not find a complete picture, but a 12-week fragment (http://salvatorepecoraro.com/365_skies_giclee.php) with a caption saying that “Pecoraro took a color-slide photograph of each day of 1970 at different times and places in California”. Even so, there were several contrails captured on different days.
If anything that section of Pecoraro’s work has MORE contrails that the video. Here’s the full work (you can’t really see the contrails in this though)
It looks like it’s organized a week per column, with summer in the middle.
It would be interesting to see that for several years. The overall pattern would be similar, but with a lot of randomness.
There are six years worth of British sky images in this photostream:
They are for the most days but not every day of the year, however.
Thanks Alexey. Reminds me how gloomy England was
Here’s a 365 photo set from Hawai’i
Very interesting article about the strange and unique properties of water and ice crystal formation.
