LANCE Data Access and Tools

NASA's Land, Atmosphere Near Real-Time Capability for Earth observation (LANCE) delivers satellite data and imagery much quicker than standard (science quality) processing—usually within three hours. These near real-time and expedited products help track rapidly changing events such as wildfires, dust and ash plumes, severe storms, changing air quality, sea ice movement, and other rapidly evolving environmental conditions.

Explore LANCE data by searching for a specific satellite, instrument, or keyword, and near real-time products, which are labeled with "NRT" to make them easy to identify. Many of these datasets can also be viewed interactively through NASA's Worldview tool.
