NASA Worldview is an interactive web-based tool that allows users to visualize and explore satellite imagery from NASA’s Earth Observing System. It offers access to over 1,200 global, full-resolution satellite imagery layers, allowing users to explore various datasets related to Earth's atmosphere, land, oceans, and cryosphere.
Many imagery layers are updated within three hours of observation, providing near real-time views of Earth's conditions. This feature is particularly beneficial for time-sensitive applications such as wildfire management, air quality monitoring, and flood surveillance. Users can interactively browse, compare, animate, and download imagery. The platform supports visualization of natural events like wildfires, tropical storms, and volcanic eruptions through its "Events" tab. The dataset accessible through Worldview is extensive, with NASA's Earth science data archive exceeding 100 PB. Worldview provides access to historical satellite imagery dating back to 2000, enabling users to explore changes over time. The
dataset is organized into various sub-datasets, each focusing on specific earth observation parameters:
-
Corrected Reflectance (True Color): Provides natural-looking images by combining data from specific spectral bands, useful for observing land surface, oceanic, and atmospheric features.
-
Chlorophyll-a Concentration: Offers data on the near-surface concentration of chlorophyll-a, aiding in the assessment of marine ecosystem productivity and health.
-
Photosynthetically Available Radiation (PAR): Displays the amount of light available for photosynthesis over the ocean and large bodies of water, measured in Einstein/m²/day.
-
Black Marble Nighttime Imagery: Provides nighttime light data, useful for assessing anthropogenic sources of light emissions and monitoring nighttime phenomena.
-
Brightness Temperature: Offers observations of brightness temperature, useful for distinguishing features in clouds and over clear land, as well as land, sea ice, and open water over polar regions during winter.
