Two decades of planetary change are available to explore in NASA's Worldview. Detailed views of volcanoes fuming, hurricanes flooding, dams being built, and wildfires sweeping across landscapes are just some of the data accessible. Worldview users can even create data animations at the touch of a button and easily share imagery, giving NASA's worldwide audience the ability to interactively view their world their way and interactively explore almost 20 years of planetary change.

Like orbiting sentinels, NASA’s Earth-observing satellites vigilantly monitor our planet’s ever-changing pulse from their unique vantage points in orbit. This animation shows the orbits of all of the current satellite missions. The flight paths are based on actual orbital elements. These missions—many joint with other nations and/or agencies—are able to collect global measurements of rainfall, solar irradiance, clouds, sea surface height, ocean salinity, and other aspects of the environment. Together, these measurements help scientists better diagnose the “health” of the Earth system.This animation will be regularly updated to show the orbits of the current earth observing fleet. This most recent version, published in March 2017, includes the CYGNSS constellation and DSCOVR at L1. Visit the original page here.Previous versions from recent years include:entry 4274 a February 2015 version including SMAPentry 3996 a spring 2014 version including GPM entry 4070 a May 2013 version which added Landsat-8entry 3892 a Dec 2011 version which added Suomi NPP and Aquariusentry 3725 a version from June 2010 ||

The vast majority of Russian wildfires occur in Siberia, generally along the southern border. This year’s blazes have followed the typical pattern and occurred primarily east of the Urals. This pair of images from August 3, 2012 shows fires using two different instruments. The Suomi National Polar-orbiting Partnership (NPP) satellite carries an instrument called the “day-night band,” designed to be sensitive to such low levels of visible light that it can detect wildfires in the dark of the night. On August 3, 2012, the Visible Infrared Imaging Radiometer Suite (VIIRS) on Suomi NPP acquired the right image of wildfires blazing in eastern Siberia. The white outlines are the actively burning perimeters of several fires. ||

NASA's Goddard Space Flight Center has the largest collection of Earth scientists on the planet. Their job is to be the nation's trusted source of comprehensive environmental information about the current state and the future of Earth. They build, design, launch and operate scientific missions, including satellites and airborne campaigns, as well as ground campaigns, to understand how the Earth works and how to predict how the Earth will change in the future.Complete transcript available.Watch this video on the NASA Goddard YouTube channel. || 13523_Goddard_Earth_Science_AGUTV.01840_print.jpg (1024x576) [49.0 KB] || 13523_Goddard_Earth_Science_AGUTV.01840_searchweb.png (180x320) [45.3 KB] || 13523_Goddard_Earth_Science_AGUTV.01840_thm.png (80x40) [4.0 KB] || 13523_Goddard_Earth_Science_AGUTV-prores.mov (1920x1080) [6.0 GB] || 13523_Goddard_Earth_Science_AGUTV-youtube.mp4 (1920x1080) [749.4 MB] || 13523_Goddard_Earth_Science_AGUTV-facebook.mp4 (1920x1080) [563.5 MB] || 13523_Goddard_Earth_Science_AGUTV-twitter.mp4 (1280x720) [101.5 MB] || 13523_Goddard_Earth_Science_AGUTV-youtube.webm (1920x1080) [51.3 MB] || 13523_Goddard_Earth_Science_AGUTV-captions.en_US.srt [9.4 KB] || 13523_Goddard_Earth_Science_AGUTV-captions.en_US.vtt [9.4 KB] ||

In the days following landfall of Hurricane Sandy, millions remained without power. This pair of images shows the difference in city lighting across New Jersey and New York before (August 31, 2012), when conditions were normal, and after (November 1, 2012) the storm. Both images were captured by the Visible Infrared Imaging Radiometer Suite (VIIRS) “day-night band” onboard the Suomi National Polar-orbiting Partnership satellite, which detects light in a range of wavelengths and uses filtering techniques to observe signals such as gas flares, city lights, and reflected moonlight.In Manhattan, the lower third of the island is dark on November 1, while Rockaway Beach, much of Long Island, and nearly all of central New Jersey are significantly dimmer. The barrier islands along the New Jersey coast, which are heavily developed with tourist businesses and year-round residents, are just barely visible in moonlight after the blackout. ||

This new space-based view of Earth's city lights is a composite assembled from data acquired by the Suomi National Polar-orbiting Partnership (Suomi NPP) satellite. The data was acquired over nine days in April 2012 and thirteen days in October 2012. It took the satellite 312 orbits and 2.5 terabytes of data to get a clear shot of every parcel of Earth's land surface and islands. This new data was then mapped over existing MODIS Blue Marble imagery to provide a realistic view of the planet.The view was made possible by the "day-night band" of Suomi NPP's Visible Infrared Imaging Radiometer Suite. VIIRS detects light in a range of wavelengths from green to near-infrared and uses "smart" light sensors to observe dim signals such as city lights, auroras, wildfires, and reflected moonlight. This low-light sensor can distinguish night lights tens to hundreds of times better than previous satellites. ||

These maps show Earth's average monthly solar insolation, or the rate of incoming sunlight reaching the surface, from July 2006 to the present as derived from Clouds and Earth’s Radiant Energy System (CERES) measurements of radiant energy escaping the top of Earth's atmosphere. The CERES instrument flies onboard NASA’s Terra and Aqua satellites and makes these measurements every day on a global scale. The colors represent the kilowatt-hours of sunlight falling on every square meter of the surface per day, averaged over one month. Energy from the sun warms the surface, creating updrafts of air that carry warmth and moisture up into the atmosphere. Thus, knowing the rate of sunlight reaching the surface helps scientists understand weather and climate patterns. Exposure to sunlight is also a key limit to plant growth, particularly in tropical rainforests. Thus, insolation maps are also useful to scientists studying plant growth patterns in different parts of the world. ||
