How is the Landsat 8 and Landsat 9 Coastal/Aerosol Band 1 used?
The Operational Land Imager Band 1 (0.433-0.453 µm) on Landsat 8 and Landsat 9 is useful for imaging shallow water and tracking fine atmospheric particles like dust and smoke.
Band 1 reflects blues and violets, where light is scattered by dust, smoke, and water particles in the air. Collecting data with enough sensitivity at this spectrum is difficult. Since water absorbs and scatters light, oceans and lakes tend to look dark or lack detail on satellite images. This is especially true in the sediment-laden waters near coastlines, where subtle differences in the color of intensity can indicate what is mixed in the water. Scientists have used the coastal band to monitor chlorophyll concentrations and suspended sediments in the water, as well as phytoplankton and algae blooms.

How is the Landsat 8 and Landsat 9 Cirrus Band 9 used?
The Operational Land Imager’s Band 9 1.360-1.390 µm on Landsat 8 and Landsat 9 detects thin, high-altitude clouds composed of ice crystals that might not be visible in other spectral bands. In Band 9, cirrus clouds appear bright while most land surfaces appear dark through an otherwise cloud-free atmosphere containing water vapor.

What are the best Landsat spectral bands for use in my research?
The Spectral Characteristics Viewer is an interactive tool that can be used to visualize how the bands, or channels, of different satellite sensors measure the intensity of the many wavelengths (colors) of light. This is also known as the relative spectral response (RSR). By overlaying the spectral curves from different features (spectra), one can determine which bands of the selected sensor will...
Are there any restrictions on the use or redistribution of Landsat data?
There are no restrictions on Landsat data downloaded from the USGS; it can be used or redistributed as desired. We do request that you include a statement of the data source when citing, copying, or reprinting USGS Landsat data or images. Details are on the EROS Data Citation page.

How is the percentage of cloud cover calculated in a Landsat scene?
The C Function of Mask (CFMask) algorithm is used in Landsat Collection 1 Level-1 data processing. This algorithm provides a full-image “Scene Cloud Cover” estimation of the percentage of cloud cover calculated over an entire Landsat scene. Land Cloud Cover, which is also included, is determined by calculating the percentage of clouds over land-only pixels in a scene using a mask that...

Landsat 8 reveals algal bloom off Brazil's coast near Sao Paulo, 2017
In early September 2017, Landsat 8 captured this image of what looked like an oil spill off the coast of Brazil, near Sao Paulo. The "oil" turned out to be a vast algal bloom that covered more than 100 km. This bloom was the result of a species of tiny dinoflagellate that multiplied quickly to produce astronomical numbers -- enough to color the ocean water.
