How is the Landsat 8 Coastal/Aerosol Band 1 used?

Landsat 8’s Band 1 (0.433-0.453 µm) is useful for imaging shallow water and tracking fine atmospheric particles like dust and smoke.

Since water absorbs and scatters light, oceans and lakes tend to look dark or lack detail on satellite images, especially in the sediment-laden waters near coastlines. Band 1 reflects blues and violets and displays subtle differences in the color of water; these changes in color 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.

This band is also useful in tracking and estimating the concentration of fine aerosol particles such as smoke and haze in the atmosphere.

How is the Landsat 8 Cirrus Band 9 used?

Landsat 8's Band 9 1.360-1.390 µm 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 band designations for the Landsat satellites?

The sensors aboard each of the Landsat satellites were designed to acquire data in different ranges of frequencies along the electromagnetic spectrum ( View Bandpass Wavelengths for all Landsat Sensors ). The Multispectral Scanner (MSS) carried on Landsat 1,2,3,4 and 5 collected data in four ranges (bands); the Thematic Mapper (TM) sensor on...

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-...

What Landsat data products are available?

There are several Landsat data products that are useful for science applications and land use/land change studies: Landsat Collections Level 1 - Ensures that the data in the Landsat Level-1 archive are consistent in processing and data quality to support time-series analyses and data stacking. Each Level-1 data product includes individual spectral...

Does Landsat Level-1 data processing include atmospheric correction?

Landsat Collection 1 Level-1 data are not corrected for atmospheric conditions, however Landsat Science Products , which include Level-2 Surface Reflectance and Provisional Surface Temperature, and Level-3 Burned Area, Dynamic Surface Water Extent, and Fractional Snow Covered Area are atmospherically corrected.

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.

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...

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.
