Proximal remote sensing: an essential tool for bridging the gap between high‐resolution ecosystem monitoring and global ecology

New Phytologist, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 23, 2025

Summary A new proliferation of optical instruments that can be attached to towers over or within ecosystems, ‘proximal’ remote sensing, enables a comprehensive characterization terrestrial ecosystem structure, function, and fluxes energy, water, carbon. Proximal sensing bridge the gap between individual plants, site‐level eddy‐covariance fluxes, airborne spaceborne by providing continuous data at high‐spatiotemporal resolution. Here, we review recent advances in proximal for improving our mechanistic understanding plant processes, model development, validation current upcoming satellite missions. We provide best practices availability metadata sensing: spectral reflectance, solar‐induced fluorescence, thermal infrared radiation, microwave backscatter, LiDAR. Our paper outlines steps necessary making these streams more widespread, accessible, interoperable, information‐rich, enabling us address key ecological questions unanswerable from space‐based observations alone and, ultimately, demonstrate feasibility technologies critical local global ecology.

Airborne imaging spectroscopy surveys of Arctic and boreal Alaska and northwestern Canada 2017–2023

Scientific Data, Journal Year: 2025, Volume and Issue: 12(1)

Published: April 25, 2025

Abstract Since 2015, NASA’s Arctic Boreal Vulnerability Experiment (ABoVE) has investigated how climate change impacts the vulnerability and/or resilience of permafrost-affected ecosystems Alaska and northwestern Canada. ABoVE conducted extensive surveys with Next Generation Airborne Visible/Infrared Imaging Spectrometer (AVIRIS-NG) during 2017, 2018, 2019, 2022 AVIRIS-3 in 2023 to characterize tundra, taiga, peatlands, wetlands unprecedented detail. The AVIRIS dataset comprises ~1700 individual flight lines covering ~120,000 km 2 nominal 5 m × spatial resolution. Data include transects capture important gradients like tundra-taiga ecotone maps up 10,000 for key study areas Mackenzie Delta. enable diverse ecosystem science, provide crucial benchmark data validating retrievals from PACE, PRISMA, EnMAP satellite sensors help prepare SBG CHIME missions. This paper guides interested researchers fully explore spectral imagery complements our guide airborne synthetic aperture radar surveys.

Decelerating Response of Western US Runoff to Shrinking Snowpacks

Geophysical Research Letters, Journal Year: 2025, Volume and Issue: 52(9)

Published: May 10, 2025

Abstract Climate warming threatens snowmelt‐derived water supplies in the western US (WUS) by reducing snowfall and snowmelt runoff, yet future rates of these declines remain highly uncertain an evolving climate. Here, we analyze historical data, land surface model experiments, climate projections across three major WUS river basins. We find that runoff loss become less sensitive to as snowpack shrinks, stemming from reduced snowmelt‐radiation feedback, a consequence smaller snow‐cover changes shifts timing lower‐energy periods. Near‐linear projected with time (IPCC SSP245) exhibit stable, possibly decelerating decline ratios. Although do not eliminate broader water‐management challenges under continued warming, our findings complement view feedback drives highlighting negative shrinking on sensitivity. Our should facilitate more comprehensive supply assessments snow‐affected regions.
