NASA’s constellation of Earth observing satellites constantly collect data about Earth and acquire some pretty amazing images of our planet. NASA's Worldview imagery mapping and visualization application lets you interactively explore this tremendous trove of NASA Earth science data and imagery—and even create snapshots and animated GIFs to share with friends. This Earth Day imagery gallery provides tips for exploring the Worldview gallery images, resources to show you how NASA studies Earth, and links to activities to help you learn more about how our amazing planet works.
Creating your own NASA Worldview Earth Day image is easy. Start with this tutorial:

Hurricane Dorian made landfall on the Bahamas at 16:40 UTC (12:40PM ET), on September 1, 2019 as a Category 5 hurricane (indicating winds greater than 155 mph). This Geostationary Operational Environmental Satellite-East (GOES-East) Clean Infrared (10.3μm, Band 13) image acquired on September 1, 2019, at 17:00 UTC (1:00PM ET) shows that the cloud-top brightness temperatures near the center of the hurricane are below -70°C (-94°F).
Viewing Tips: Hover over the different colors in the image to see the corresponding temperature value in the Layer List in NASA Worldview. This layer is useful for detecting clouds during the day and at night and aiding in cloud and other atmospheric feature identification and classification.

Raikoke Volcano Eruption, Kuril Islands, Russia
This true-color corrected reflectance image of the ash plume from the Raikoke Volcano eruption was acquired on June 22, 2019 by the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument, aboard NASA's Terra satellite. This volcano is located within the Kuril Islands on the Kamchatka Peninsula in Russia.
Viewing Tips: The brown plume in the center of the image is the ash plume from the eruption. To see how this ejected aerosols into the atmosphere, go to NASA Worldview and turn on the Aerosol Index Suomi National Polar orbiting Partnership / Ozone Mapping Profiler Suite (Suomi NPP / OMPS) layer to see the high levels of aerosols shown in red. The Aerosol Index is a unitless range from <0.00 to >=5.00, where 5.0 indicates heavy concentrations of aerosols that could reduce visibility or impact human health.

Nighttime Lights - United States
Viewing Earth at night affords us a different view of Earth's surface. We may be used to seeing the true-color satellite images that mimic what the human eye perceives, but the night lights layer shows Earth at night and the illuminations that emanate from Earth back into space.
Viewing Tips: What are the three or four major cities that can be viewed in this image? Explore this image in NASA Worldview and turn on the Place Labels layer to see what cities are along this major highway corridor.
