Landsat Collections Real-Time (RT) data is provided 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 immediately after acquisition. Estimated radiometric and geometric calibration parameters are applied to these scenes. When final radiometric and geometric calibration parameters are calculated (about 16 days for Landsat 8), the RT scenes are reprocessed with the more precise calibration parameters and placed into either Tier 1 or Tier 2.
Newly acquired Landsat 9 scenes are immediately placed into Tier 1 or Tier 2 and available for download within 4-6 hours after acquisition.

Landsat Collection Tiers are the inventory structure for Level-1 data products and are based on data quality and level of processing. The tier definition purpose is to support easier identification of suitable scenes for time-series pixel-level analysis, and provide temporary data that are processed immediately upon downlink to be dispensed quickly in emergency response situations with limited...
Data that is processed to meet Collections specifications has a Landsat Product Identifier, as opposed to the historical Landsat Scene ID. Along with information inherited from the Scene ID, the Landsat Product Identifier includes the processing level, processing date, collection number, and collection category (bolded below). Scene ID Landsat Product Identifier LXSPPPRRRYYYYDDDGSIVV LXSS_LLL...
In 2016, the USGS reorganized the Landsat archive into a tiered collection. This structure ensures that Landsat Level-1 products provide a consistent archive of known data quality to support time-series analyses and data “stacking”, while controlling continuous improvement of the archive and access to all data as they are acquired.

The Landsat Collection 1 Level-1 product identifier includes the Collection processing levels, processing date, collection number, and collection tier category: LXSS_LLLL_PPPRRR_YYYYMMDD_yyyymmdd_CC_TX Where: L = Landsat X = Sensor (“C”=OLI/TIRS combined, “O”=OLI-only, “T”=TIRS-only, “E”=ETM+, “T”=“TM, “M”=MSS) SS = Satellite (”07”=Landsat 7, “08”=Landsat 8) LLL = Processing correction level (L1TP...
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...
Landsat scenes become available through EarthExplorer within 6 hours after acquisition and become visible in GloVis within 24 hours. See Landsat Acquisitions for acquisition calendars and information about daily schedules.
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.

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...
The tragic fires sweeping across the Greater Los Angeles area in January 2025 have burned more than 40,000 acres, destroyed more than 12,300 structures, and prompted evacuation orders and warnings for as many as 200,000 residents. Exceptionally dry conditions, coupled with strong Santa Ana winds, have fueled the fires.

Found along the Pacific Ring of Fire, Russia’s Shiveluch Volcano began erupting on April 11, 2023. Huge ash clouds spewed from the main crater blanketing over 40,000 square miles (108,000 square kilometers). The tiny village of Klyuchi, about 30 mi (50 km) from the volcano, plunged into darkness.

Landsat images from March of 2018 and March of 2019 show a stretch of the Missouri, Platte, and Elkhorn rivers in a full scene that stretches from just north of Sioux City, IA, to south of Omaha, NE. The first image shows the rivers at normal levels.
