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.

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). Formulas for these conversions are at Using the...
What are the acquisition schedules for the Landsat satellites? What are the acquisition schedules for the Landsat satellites?
The Landsat 8 and Landsat 9 satellites orbit the Earth at an altitude of 705 kilometers (438 miles) in a 185 kilometer (115 miles) swath, moving from north to south over the sunlit side of the Earth in a sun synchronous orbit. Each satellite makes a complete orbit every 99 minutes, completes about 14 full orbits each day, and crosses every point on Earth once every 16 days. The satellite orbits...
What are the band designations for the Landsat satellites? What are the band designations for the Landsat satellites?
The sensors onboard each of the Landsat satellites were designed to acquire data in different wavelengths within 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 Landsat 4 and Landsat 5 included those bands found on earlier...
