Two Decades of Earth Data

Powerful Earth-observing instruments aboard NASA's Terra and Aqua satellites, launched in 1999 and 2002, respectively, have observed nearly two decades of planetary change. Now, for the first time, all that imagery—from the first operational image to imagery acquired today—is available for exploration in Worldview.

Both satellites carry Moderate Resolution Imaging Spectroradiometer (MODIS) instruments that have been taking images of Earth – showing more than 18 years of change on our home planet.

The data in Worldview features the longest continuous daily global satellite observation record of Earth ever compiled. For researchers, the ability to rapidly access and explore all MODIS global imagery greatly improves their use of these data.
