Tropical leaf phenology as a thermoregulation trait: how changes in crown structure modulate thermal dynamics for two dominant Hawaiian trees

New Phytologist, EarlyView.
Study site and focal species. Summary Canopy and leaf temperatures often diverge from air temperature, influencing photosynthesis, water loss, and heat stress. While leaf traits are known to affect heat exchange, how changes in crown structure interact with environmental drivers to regulate canopy thermal dynamics is poorly understood, particularly in ...

Relative radiometric calibration of LANDSAT TM reflective bands [PDF]

, 1984
Raw thematic mapper (TM) calibration data from pre-launch tests and in-orbit acquisitions from LANDSAT 4 and 5 satellites are analyzed to assess the radiometric characteristics of the TM sensor.

Polarization Radiometric Calibration in Laboratory for a Channeled Spectropolarimeter

, 2020
The process of radiometric calibration would be coupled with the polarization properties of an optical system for spectropolarimetry, which would have significant influences on reconstructed Stokes parameters.

Multi‐Subunit Engineering of Photorespiratory Glycine Decarboxylase Refines Photosynthesis, Growth and Metabolic Robustness of Arabidopsis

Plant, Cell &Environment, EarlyView.
ABSTRACT Photorespiration secures oxygenic photosynthesis from metabolic constraints arising from the oxygenation reaction of Rubisco in today's oxygen‐rich atmosphere. Beyond this protective function, it is vital for primary metabolism, cellular redox balance, and stomatal regulation.

OpsSatNet: A Lightweight Sensor-Aware Attention Network for Satellite Telemetry Anomaly Detection

Sensors
Satellite housekeeping systems combine heterogeneous sensor channels that require continuous fault monitoring. Existing methods rely mainly on hand-crafted statistics or generic raw-signal models, which can obscure localized morphology and do not ...

Conditions and timing for the precipitation of early marine diagenetic dolomite in the Triassic Dolomia Principale (northern Italy)

Sedimentology, EarlyView.
ABSTRACT Thermodynamic constraints and empirical evidence often suggest that fabric‐retentive replacement dolomites are stable carbonate minerals that preserve ancient seawater properties. This study evaluates this hypothesis by examining the Upper Triassic Dolomia Principale in Northern Italy.

Radiometric Calibration of SAR-Sensors.

, 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 ...
