Radiometric Calibration of SAR-Sensors.

open access: yes, 1997
Radiometric calibration of Synthetic Aperture Radar (SAR) sensors requires three major steps: Internal calibration including preflight characterisation of the sensor electronics and inflight monitoring of any variations of the transmit power and the ...

Impact of Urban Environmental Indices on Surface Temperature in Dhaka: A Policy‐Oriented Perspective

open access: yesClimate Resilience and Sustainability, Volume 5, Issue 1, June 2026.
ABSTRACT Dhaka's rapid urban expansion has intensified surface heating and degraded environmental quality. This study analyzes environmental indices from 2015 to 2025, revealing a strong positive relationship between built‐up growth and land surface temperature, and negative associations with vegetation and water presence.

Quantification of the Eocene–Oligocene transition in the Zagros Foreland Basin: Palaeogeographic control on sequence architecture and tectonic signal preservation

open access: yesThe Depositional Record, Volume 12, Issue 3, June 2026.
New bio‐sequence framework for the Eocene–Oligocene transition in Zagros. Geochemical data validate basin depth control on SB1 vs. SB2 boundaries. SEM‐EDS analyses confirm subaerial exposure versus continuous deposition. Sensitivity analysis quantifies sub‐10% uncertainty in stratigraphic interpretations. Resolves the Pyrenean orogeny's variable impact

Traceable Radiometric Calibration of Synthetic Aperture Radars

open access: yes, 2016
Synthetic aperture radar (SAR) systems allow to quantitatively measure the radar backscatter of an imaged terrain region. In order to achieve comparability between measurement results, traceable radiometric calibration is indispensable.

Determinants of Bird Richness in the Louzishan National Nature Reserve: Effects of Productivity and Habitat Heterogeneity Across Taxonomic and Functional Dimensions

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
We want to reveal the relationship between the alpha and beta diversity of birds and its two components with vegetation productivity and habitat heterogeneity from both taxonomic and functional perspectives. Our findings reveal productivity, as an important environmental variable, influences bird species richness and compositional differences from two ...

PROBA-V Commissioning: Radiometric Calibration

open access: yes, 2013
The Belgian-ESA Proba-V(egetation) satellite is to be launched in April 2013. The aim of the Proba-V mission is to ensure data product continuity with SPOT-VEGETATION, which ends its operations in 2014.

Vegetation on the move: elevational shifts and greening dynamics across the Himalayan alpine zone

open access: yesEcography, Volume 2026, Issue 6, June 2026.
This study investigates alpine ‘vegetation line' (the upper limit of continuous plant community) dynamics in the Himalayan alpine zone (HAZ) over a 24‐year timescale (1999–2022) using maximum NDVI products derived from Landsat series datasets, adjusted for sampling bias using phenological modelling.

Radiometric Calibration of Osmi Imagery Using Solar Calibration

open access: yes, 2000
OSMI (Ocean Scanning Multi-Spectral Imager) raw image data (Level 0) were acquired and radiometrically corrected. We have applied two methods, using solar & dark calibration data from OSMI sensor and comparing with the SeaWiFS data, to the radiometric ...
