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.

Square satellie image that is mostly grey with small blobs and wisps of white clouds

Landsat 8 Path 112 Row 66 acquired August 3, 2013. Image shows cirrus clouds visible using Cirrus band 9. Landsat 8's Band 9 (1.360-1.390 µm) provides detection of high-altitude cloud contamination that may not be visible in other spectral bands. Cirrus clouds appear bright while most land surfaces will appear dark through cloud-free atmospheres containing water vapor.

How do I search for and download Landsat data?

Landsat data products held in the USGS archives can be searched and downloaded at no charge from a variety of sources. Visit the Landsat Data Access web page for information about how Landsat data products can be downloaded individually or in bulk. Landsat imagery not found in the USGS archive might have been collected by one of the USGS...

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...

Can Landsat Collection Real-Time scenes be used in my research?

Landsat Collections Real-Time (RT) data provide temporary data within 12 hours of acquisition in support of the International Charter to help mitigate the effects of disasters on human life and property. The RT tier contains data received from Landsat 8 and Landsat 7 immediately after acquisition. Estimated radiometric and geometric calibration...

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-...

Why do Landsat 7 Level-1 products contain two thermal bands?

Landsat 7 acquires thermal data in two bands from one detector in both high (Band 6H) and low (Band 6L) gain. The difference in gain settings is important to different types of studies (i.e., clouds vs. deserts). Aside from the resolution differences and saturation on the high and low ends, the two bands provide the same Digital Numbers (DN) for...

How do I rescale Landsat Level-1 digital numbers to reflectance, radiance, and brightness temperature?

Landsat Level-1 data can be rescaled to the top of atmosphere (TOA) reflectance and/or radiance using radiometric rescaling coefficients provided in the metadata file (MTL.txt) that is delivered with the Landsat Level-1 product. The MTL file also contains the thermal constants needed to convert thermal band data to TOA brightness temperature (BT...

What are the acquisition schedules for the Landsat satellites?

The Landsat 7 and Landsat 8 satellites orbit the Earth at an altitude of 705 kilometers (438 miles) in a 185-kilometer (115-mile) swath, moving from north to south over the sunlit side of the Earth in a sun synchronous orbit, following the World Reference System (WRS-2) . Each satellite makes a complete orbit every 99 minutes, completes about 14...

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...
