During the 9th of July of 2007, a snowstorm took place in the metropolitan area of the city of Buenos Aires for the first time in 89 years. Since July 9th is a national holiday, crowds gathered in the streets and parks all over the city to experience snow, most for the first time in their lives.
Using 155 images collected by NASA’s AQUA satellite during the 9th of July of 2007, an 11 by 5 foot mosaic was created by arranging the images in a grid according to the time of the day that they were taken (one image is taken every 5 minutes). The mural is composed by 24 columns and 12 lines that depict Earth’s weather system on the day of the snowstorm. Since the satellite doesn’t’ capture information in the dark side of the Earth (nighttime), sections of the grid were left empty.
