The Earth: Blue Marble 2012 - Arctic View

Hi My Friends: A VUELO DE UN QUINDE EL BLOG., A 'Blue Marble' image of the Earth taken from the VIIRS instrument aboard NASA's most recently launched Earth-observing satellite - Suomi NPP. This composite image uses a number of swaths of the Earth's surface taken on January 4, 2012.

The Visible/Infrared Imager Radiometer Suite or VIIRS is the primary imaging instrument onboard NPP, and it acquires data in 22 spectral bands covering visible, near-infrared, and thermal infrared regions of the electromagnetic spectrum.

Behind the Scenes

NASA scientist Norman Kuring managed to 'step back' from Earth to get the big picture by combining data from six different orbits of the Suomi NPP satellite. Or putting it a different way, the satellite flew above this area of Earth six times over an eight hour time period. Norman took those six sets of data and combined them into one image. + view full feature

Blue Marble 2012 - Arctic View

Fifteen orbits of the recently launched Suomi NPP satellite provided the VIIRS instrument enough time (and longitude) to gather the pixels for this synthesized view of Earth showing the Arctic, Europe, and Asia.

Suomi NPP orbits the Earth about 14 times each day and observes nearly the entire surface. The NPP satellite continues key data records that are critical for climate change science.
