Landsat 8: status and on-orbit performance

SPIE Proceedings, 2015
Landsat 8 and its two Earth imaging sensors, the Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) have been operating on-orbit for 2 ½ years. Landsat 8 has been acquiring substantially more images than initially planned, typically around 700 scenes per day versus a 400 scenes per day requirement, acquiring nearly all land scenes.

Analyses of land surface temperature (LST) variability among local climate zones (LCZs) comparing Landsat-8 and ENVI-met model data

, 2021
The acceleration of urbanization has caused the urban heat island (UHI) phenomenon because it has changed the built and natural structure. In recent years, the common concept of a local climate zone (LCZ) has become the top priority for UHI studies for ...

Landsat-8 TIRS thermal radiometric calibration status

Earth Observing Systems XXII, 2017
The Thermal Infrared Sensor (TIRS) instrument is the thermal-band imager on the Landsat-8 platform. The initial onorbit calibration estimates of the two TIRS spectral bands indicated large average radiometric calibration errors, -0.29 and -0.51 W/m2 sr μm or -2.1K and -4.4K at 300K in Bands 10 and 11, respectively, as well as high variability in the ...

Crop Classification Using Multitemporal Landsat 8 Images

IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019
The objective of this study is to investigate the potential of multitemporal remote sensing images for crop classification. Multi-temporal Landsat 8 OLI/TIRS C1 Level-1 images were acquired. The surface reflectance of visible and near infrared bands was used to represent the characteristics of crops.

On-orbit performance of the Landsat 8 Operational Land Imager

SPIE Proceedings, 2014
The Landsat 8 satellite was launched on February 11, 2013, to systematically collect multispectral images for detection and quantitative analysis of changes on the Earth’s surface. The collected data are stored at the U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center and continue the longest archive of medium ...

Landsat Data Continuity Mission, now Landsat-8: six months on-orbit

SPIE Proceedings, 2013
The Landsat Data Continuity Mission (LDCM) with two pushbroom Earth-imaging sensors, the Operational Land Imager (OLI) and the Thermal InfraRed Sensor (TIRS), was launched on February 11, 2013. Its on-orbit check out period or commissioning phase lasted about 90 days.

Cross-calibration of Landsat 5 TM and Landsat 8 OLI with Aqua MODIS using PICS

SPIE Proceedings, 2014
The Thematic Mapper (TM) onboard the Landsat 5 (L5) has provided an unprecedented amount of earth observations for more than 25 years since its launch on March 1, 1984. The MODIS sensor onboard the Aqua satellite is a part of the afternoon constellation of spacecraft and has been successfully providing near-continuous observations of the earth’s ...

Landsat-8 TIRS radiometric calibration status

Earth Observing Systems XXV, 2020
The Landsat-8 Thermal Infrared Sensor (TIRS) has been acquiring two-band thermal infrared images of the Earth’s surface since 2013. The calibration of the two-band system has been monitored using the on-board calibrator and validated with vicarious calibration performed by NASA/Jet Propulsion Laboratory and Rochester Institute of Technology since ...
