We are in the process of migrating all NASA Earth science data sites into Earthdata from now until end of 2026. Not all NASA Earth science data and resources will appear here until then. Thank you for your patience as we make this transition.

Reflectance Data Access and Tools
From discovery to visualization, data tools such as Worldview, Earthdata Search, and Fire Information for Resource Management System (FIRMS) guide users in making the most of reflectance data.
Featured Reflectance Observation Method: MODIS
The Moderate Resolution Imaging Spectroradiometer (MODIS) is a key instrument aboard the Terra and Aqua platforms. Terra and Aqua survey Earth's surface every one to two days, acquiring data in 36 spectral bands. The MODIS surface reflectance products provide an estimate of the surface spectral reflectance as it would be measured at ground level in the absence of atmospheric scattering or absorption.
Join us to learn how to discover, subset, access and visualize both MODIS and VIIRS data products using a suite of user-friendly tools developed by NASA's ORNL DAAC.
Scientists develop routine service for wildfire detection in the continental United States with a latency of less than 60 seconds.
