Burn Scar - Corrected Reflectance (VIIRS / Suomi-NPP)
URL: https://modis.arcgis.com/arcgis/rest/services/VIIRS/ImageServer
Visualization Overview This visualization represents a "false color" band combination (M11-I2-I1, Red-Green-Blue) of data collected by the VIIRS instrument on the joint NASA/NOAA Suomi-NPP satellite. The imagery is most useful for distinguishing burn scars from naturally low vegetation or bare soil and enhancing floods.
The following guidelines will aid in understanding this visualization. See here for a full description of how the bands are combined to highlight these physical characteristics of the Earth. Vegetation will appear bright green. Naturally bare soil, like a desert, will often appear to have a pinkish tinge. Burned areas (a.k.a. "burn scars") will appear as deep or bright red, depending on the type of vegetation burned, the amount of residue, or the completeness of the burn. Liquid water on the ground will appear dark blue while ice and snow will appear as bright turquoise. Clouds lower to the ground will appear white while high, and cold, clouds will appear turquoise. The VIIRS Corrected Reflectance product provides natural-looking images by removing gross atmospheric effects such as Rayleigh scattering from the visible bands. By contrast the VIIRS Surface Reflectance product provides a more complete atmospheric correction algorithm that includes aerosol correction and is designed to derive land surface properties. In clear atmospheric conditions the Corrected Reflectance product is similar to the Surface Reflectance product, but they depart from each other in the presence of aerosols.
In this visualization you will see a "daily composited" image that provides a continuous browsing experience. As you change the date within the ArcGIS map viewer, you will see the composited imagery for that day. When viewing imagery for the current day (UTC), you may notice that only a portion of the map has imagery. This is because the visualization is updated as a part of the the NASA Near Real-Time capability, which generates data and visualizations within 3-hours of acquisition. Currently, this layer is available from present back to November 24th, 2015. In the coming months, this will be extended to the start of the mission (October 28th, 2011).
NASA Global Imagery Browse Services (GIBS) & NASA Worldview This visualization is provided through the NASA Global Imagery Browse Services (GIBS), which are a set of standard services to deliver global, full-resolution satellite imagery for hundreds of NASA earth science datasets and science parameters. Through its services, and the NASA Worldview client, GIBS enables interactive exploration of NASA's Earth imagery for a broad range of users.
Esri and NASA Collaborative Services This visualization is made available through an Esri mosaic service hosted on Esri servers and facilitates access to a NASA GIBS service endpoint. For each mosaic service request, the Esri server issues multiple requests to the GIBS image service, processes and assembles the responses, and returns a proper mosaic image to the user. Processing occurs on-the-fly for each and every request to ensure that any update to the GIBS imagery is immediately available through the Esri mosaic service. As such, availability of this visualization is dependent on both the Esri mosaic service and the NASA GIBS service.
