Characterization of LCDs Using Partition Scaling and Unique Hue Methods

open access: yesColor Research &Application, Volume 51, Issue 2, March/April 2026.
Partition scaling, a key method in the proposed visually based characterization model, produced experimental results that can be well described by the relationship between the normalized lightness step (LS) and luminance (Y). ABSTRACT This study investigates the feasibility of using psychophysical methods to establish a colorimetric characterization ...

Estimating Plant Species Richness With Sentinel and Landsat Data Across Ecosystems in China

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
438 field plots were used to estimate plant diversity across ecosystems; 18 spectral indices were derived from Sentinel and Landsat data; EVI, DVI, PSRI, NDVI, PRI, GNDVI, and GMEVI were identified as powerful indicators for predicting plant alpha diversity.

Quantifying river morphological changes using multi‐satellite observations and in situ measurements

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
This study integrates optical, radar and altimetry satellite data with river gauge measurements to estimate periodically submerged riverbed topography and quantify morphological change. By linking how often water covers the riverbed with water‐level variations, erosion and deposition patterns are mapped across a reach of Jamuna River.

Inversion of Net Photosynthetic Rate in Winter Rapeseed Based on UAV Multispectral Vegetation Indices and Texture Features

open access: yesFood and Energy Security, Volume 15, Issue 2, March/April 2026.
ABSTRACT Net photosynthetic rate (Pn) serves as a key indicator for evaluating plant growth and yield. In order to explore an effective method for monitoring winter rapeseed Pn using unmanned aerial vehicle (UAV) multispectral technology, the winter rapeseed was taken as the research object and the multispectral images were obtained through UAVs in ...

Methane Retrieval Algorithms Based on Satellite: A Review

open access: yesAtmosphere
As the second most predominant greenhouse gas, methane-targeted emission mitigation holds the potential to decelerate the pace of global warming. Satellite remote sensing is an important monitoring tool, and we review developments in the satellite ...

The Importance of Spatial Variability in Estimating Evapotranspiration From a Subalpine Wetland

open access: yesHydrological Processes, Volume 40, Issue 3, March 2026.
Spatial trends in evapotranspiration were quantified in a sub‐alpine wetland, with higher rates occurring in the wetlands' western portion. This spatial variability suggests care must be taken when estimating evapotranspiration via point measurements. The METRIC approach to modelling evapotranspiration performed reasonably well and should be explored ...
