Intercomparison of Global Solar Induced Chlorophyl Fluorescence Products

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Satellite observations of Sun‐Induced Chlorophyll Fluorescence (SIF) provide a powerful means to assess terrestrial photosynthesis at regional to global scales, yet major SIF products differ in retrieval strategy, radiometric stability, and sensitivity to environmental conditions.

Landsat-8 data processing evolution

SPIE Proceedings, 2014
Shortly after Landsat-8 launched in February 2013, the U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center began creating radiometrically and geometrically corrected products. In order to provide these products as soon as possible, the Landsat Product Generation System (LPGS) was developed based on instrument designs and

Statistical relative gain calculation for Landsat 8

Earth Observing Systems XXII, 2017
The Landsat 8 Operational Land Imager (OLI) is an optical multispectral push-broom sensor with a focal plane consisting of over 7000 detectors per spectral band. Each of the individual imaging detectors contributes one column of pixels to an image. Any difference in the response between neighboring detectors may result in a visible stripe or band in ...

Landsat 8 TIRS calibration with external sensors

Earth Observing Systems XXII, 2017
This paper deals with a calibration algorithm to be used with data from the Thermal Infrared Sensor (TIRS) on board Landsat 8. Some non-uniform banding calibration errors have been observed in TIRS data since it was launched in 2013. Investigations have shown that this artifact is due to out-of-field radiance that scatters onto the TIRS focal plane.

การจำแนกการใช้ประโยชน์ที่ดินด้วยวิธีการซัพพอร์ตเวกเตอร์แมชชีนจากภาพถ่ายดาวเทียม LANDSAT 8 เพื่อประเมินปริมาณการใช้น้ำในพื้นที่จังหวัดกาฬสินธุ์

2023
งานวิจัยนี้มีจุดประสงค์เพื่อเปรียบเทียบการจำแนกการใช้ประโยชน์ที่ดินจากภาพถ่ายดาวเทียม Landsat 8 ในปี พ.ศ. 2557 และ 2559 ด้วยวิธีซัพพอร์ตเวกเตอร์แมชชีน (Support Vector Machine: SVMs) กับวิธีความน่าจะเป็นไปได้สูงสุด (Maximum Likelihood Classifier: MLC) ในพื้นที่จังหวัดกาฬสินธุ์ นำผลที่ได้จากการจำแนกมาวิเคราะห์การเปลี่ยนแปลงการใช้ประโยชน์ที่ดิน เพื่อประเมิ

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.

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 ...
