Visualization OverviewThis visualization represents a "false color" band combination (Red = 7, Green = 2, Blue = 1) of data collected by the MODIS instrument on the NASA Terra satellite. The imagery is most useful for distinguishing burn scars from naturally low vegetation or bare soil and enhancing floods. At its highest resolution, this visualization represents the underlying data scaled to a resolution of 250m per pixel at the equator.The MODIS Corrected Reflectance product retains visible aerosols for a natural-looking visualization, though gross atmospheric effects (e.g. Rayleigh scattering) have been removed. The following guidelines will aid in understanding this visualization. See here for additional information on how this "false color" band combination highlights 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.Multi-Spectral BandsThe following table lists the MODIS bands that are utilized to create this visualization. See here for a full description of all MODIS bands.BandDescriptionWavelength (µm)Resolution (m)1Visible (Red)0.620 - 0.6702502Shortwave Near IR0.841 - 0.8762507Shortwave IR2.105 - 2.155500Temporal CoverageBy default, this layer will display the imagery currently available for today’s date. This imagery is a "daily composite" that is assembled from hundreds of individual data files. When viewing imagery for “today,” you may notice that only a portion of the map has imagery. This is because the visualization is continually updated as the satellite collects more data. To view imagery over time, you can update the layer properties to enable time animation and configure time settings. Currently, this layer is available from present back to the start of the mission (February 24th, 2000).NASA Global Imagery Browse Services (GIBS), NASA Worldview, & NASA LANCEThis 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. The data and imagery are generated within 3 hours of acquisition through the NASA LANCE capability.Esri and NASA Collaborative ServicesThis visualization is made available through an ArcGIS image service hosted on Esri servers and facilitates access to a NASA GIBS service endpoint. For each image service request, the Esri server issues multiple requests to the GIBS 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 to the user. As such, availability of this visualization is dependent on both the Esri and the NASA GIBS services.
