Blue Marble - 2002

    Newer Older

    This spectacular “blue marble” image is the most detailed true-color image of the entire Earth to date. Using a collection of satellite-based observations, scientists and visualizers stitched together months of observations of the land surface, oceans, sea ice, and clouds into a seamless, true-color mosaic of every square kilometer (.386 square mile) of our planet. These images are freely available to educators, scientists, museums, and the public. This record includes preview images and links to full resolution versions up to 21,600 pixels across.

    Much of the information contained in this image came from a single remote-sensing device-NASA’s Moderate Resolution Imaging Spectroradiometer, or MODIS. Flying over 700 km above the Earth onboard the Terra satellite, MODIS provides an integrated tool for observing a variety of terrestrial, oceanic, and atmospheric features of the Earth. The land and coastal ocean portions of these images are based on surface observations collected from June through September 2001 and combined, or composited, every eight days to compensate for clouds that might block the sensor’s view of the surface on any single day. Two different types of ocean data were used in these images: shallow water true color data, and global ocean color (or chlorophyll) data. Topographic shading is based on the GTOPO 30 elevation dataset compiled by the U.S. Geological Survey’s EROS Data Center. MODIS observations of polar sea ice were combined with observations of Antarctica made by the National Oceanic and Atmospheric Administration’s AVHRR sensor—the Advanced Very High Resolution Radiometer. The cloud image is a composite of two days of imagery collected in visible light wavelengths and a third day of thermal infra-red imagery over the poles. Global city lights, derived from 9 months of observations from the Defense Meteorological Satellite Program, are superimposed on a darkened land surface map.

      Thank you NASA for this beautiful overview of Earth. If any place would be central to me it would be Antarctica, don't think we fully appreciate how it impacts all our lives. Every inch of Earth is precious; that is what Earth Day is about, a reminder of how beautiful and yet fragile it really is.

      An Incredible picture but.... Can you take a picture to something different that USA?.. the world is bigger than your country.

    15. kda_1994 27 months ago | reply

      amazing...the reason it is generally of north america is because of the orbit. the other hemisphere is too close to get into one shot, they have to combine many images.

    16. scottvw213 23 months ago | reply

      why is North America bigger in this photo than in previous images of Earth?
