The Benefits of High Resolution Multispectral TIR Data and Its Impending Loss by NASA After Four Decades

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract NASA has led multispectral (≥3 wavelength bands) thermal infrared (TIR) sensor development from the earliest days of the agency. These data are critical in addressing a wide range of scientific questions and administration priories by measuring both temperature (for wildfire and volcanic eruption monitoring, agricultural plant stress, and ...

Image‐Based Multivariate Curve Resolution and Scalar Field Analysis of ERA5 Precipitation Over the Iberian Peninsula

Journal of Chemometrics, Volume 40, Issue 11, November 2026.
ABSTRACT Gridded climate reanalysis datasets can be viewed as image cubes, yet chemometric decomposition methods remain underutilized in climate data analysis. This study applied pixel‐based Multivariate Curve Resolution–Alternating Least Squares (MCR‐ALS) with a trilinearity constraint to ERA5 precipitation data over the Iberian Peninsula (1940–2024).

Hyperspectral images segmentation: a proposal [PDF]

, 2009
Hyper-Spectral Imaging (HIS) also known as chemical or spectroscopic imaging is an emerging technique that combines imaging and spectroscopy to capture both spectral and spatial information from an object. Hyperspectral images are made up of contiguous

Models of DG‐Carbon Bands in Raman Spectra: Effects of Basis Functions and Initial Values on the Uniqueness and S/N of Fits Obtained for Atmospheric Aerosol Using Automated Methods

Journal of Raman Spectroscopy, Volume 57, Issue 11, Page 1840-1864, November 2026.
Raman spectra containing D/G features are fit using combinations of basis functions and initial conditions. Fits with two Lorentzian functions converged to a single optimized fit even with variation of initial peak positions. For five‐band fits, sometimes the final fit varied with initial conditions, and constraints on peak center position were ...

HoloSpec: Dispersion‐Based 4D Computational Holographic Hyperspectral Imaging

Laser &Photonics Reviews, Volume 20, Issue 21, 6 November 2026.
HoloSpec, a compact dispersion‐based computational holographic system, achieves four‐dimensional imaging by retrieving 3D spatial structure and high‐resolution spectra from only two monochromatic snapshots. Using a single prism and a monochrome sensor, it resolves 430 spectral channels with 3 nm experimental resolution and 30 μm$\mathrm{\mu}\mathrm{m}$

Quantifying soil ammonium and nitrite via soil gas emissions

Soil Science Society of America Journal, Volume 90, Issue 6, November/December 2026.
Abstract Monitoring the soil mineral nitrogen (SMN) status of cropland is challenging due to large spatiotemporal variability. Here, we present a novel approach that correlates NH3, NO, and HONO emissions with SMN content, pH, and soil moisture, eliminating the need for destructive soil sampling. We conducted incubation experiments with five soils with

CaSSIS Resampled Data Record (CaRDR): A Near‐Global Multispectral View of Mars From CRISM‐CaSSIS Resampling

Earth and Space Science, Volume 13, Issue 11, November 2026.
Abstract The Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) Visible‐to‐near‐infrared Hyperspectral Reduced Data Record (VRDR) data set provides near‐global (∼99%) coverage of the Martian surface between 0.371 and 1.017 μm across 92 spectral channels, at a spatial resolution of 90 m/pixel.

Oil Spill Vulnerability in the Arabian/Persian Gulf Threatens Regional Water Security and Global Energy Supply

Earth's Future, Volume 14, Issue 11, November 2026.
Abstract The Arabian/Persian Gulf contains more than half of the world's proven oil reserves and is a critical hub for global energy transport, yet it faces increasing oil spill risk from intense tanker traffic, geopolitical tensions, and clandestine oil smuggling operations.
