Sensitivity of L-Band SAR Backscatter to Aboveground Biomass of Global Forests

open access: yesRemote Sensing, 2016
Synthetic Aperture Radar (SAR) backscatter measurements are sensitive to forest aboveground biomass (AGB), and the observations from space can be used for mapping AGB globally.

Aerosol Retrieval Over Ocean From DPC‐2/GF‐5(02): Using RemoTAP Extended With a 3‐Parameter Ocean Bio‐Optical Model and Comparisons With a 1‐Parameter Model

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Multi‐angle polarimetric instruments (MAPs) enable the retrieval of essential aerosol properties over oceanic regions. MAPs retrieval algorithms commonly use a 1‐parameter ocean bio‐optical model (OBM), based on chlorophyll‐a concentration only to represent optical properties over open waters (case‐1), whereas the coastal water (mixture of ...

Surface‐Constrained Reconstruction of Spatiotemporal Turbulence Dissipation in the Convective Boundary Layer Using Physics‐Guided Machine Learning

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Turbulence dissipation rate (EDR) governs the conversion of turbulent kinetic energy to heat and thereby controls vertical mixing, transport, and energy exchange in the convective boundary layer (CBL). The spatiotemporal structure of EDR remains poorly constrained, as observations are limited to point measurements or sparse vertical profiles ...

Drizzle Measurements Using High Spectral Resolution Lidar and Radar Data

open access: yesEPJ Web of Conferences, 2016
The ratio of millimeter radar and High Spectral Resolution Lidar (HSRL) backscatter are used to determine drizzle rates which are compared to conventional ground based measurements.

Climatology of Atmospheric Boundary Layer Height Over Nearshore and Open Ocean Regions of the Western North Pacific

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Atmospheric boundary layer height (ABLH) plays an important role in air–sea interactions and regional climate over the western North Pacific (WNP). Using ERA5 reanalysis data from 1979 to 2025, this paper investigates the interannual variability, monthly variations, and seasonal spatial patterns of ABLH.

How Well Can the Surface Water and Ocean Topography (SWOT) Satellite Mission Observe Irrigation Canals?

open access: yesGeophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract The capability of the Surface Water and Ocean Topography (SWOT) satellite for observing irrigation canals has remained relatively unexplored. Here, we assess SWOT observability of irrigation canal networks across 22 Asian countries using a new confidence level (CL) metric.

Assessing Co‐Located NISAR and Sentinel‐1 Observations for Atmospheric Characterization

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract Tropospheric delay remains one of the largest sources of uncertainty in repeat‐pass Interferometric Synthetic Aperture Radar (InSAR) measurements, while accurate three‐dimensional deformation retrieval continues to be limited by the geometry of current spaceborne SAR systems.
