Deep Ocean Steric Sea Level Change in the Subtropical Northwest Atlantic Ocean

open access: yesGeophysical Research Letters, Volume 52, Issue 16, 28 August 2025.
Abstract The non‐closure of the global sea level budget, detected since 2017, stimulates the need to better understand limitations of satellite altimetry and gravimetry measurements, and breakdown in situ measurement contributions and gaps. Here, temperature and salinity profiles collected in the subtropical Northwest Atlantic Ocean between 2017 and ...

The Impact of Adaptive High‐Latitude Coordinates

open access: yesGeophysical Research Letters, Volume 52, Issue 16, 28 August 2025.
Abstract The high‐latitude ionosphere can be divided into three regions dominated by different types of coupling and characterized by distinctive behaviors. These are the polar cap, the auroral region, and the sub‐auroral region. Their locations are highly variable, changing in extent in response to driving conditions in the solar wind and within the ...

Deforestation Could Push Amazonia Close to a Tipping Point Under Future Climate Change

open access: yesGeophysical Research Letters, Volume 52, Issue 15, 16 August 2025.
Abstract We use a coupled land‐surface‐atmosphere single‐column model to examine the effects of deforestation and changed advective moisture flux (AMF) on the Amazonian system. We find that from current conditions, a reduction to 35% forest cover, or a ∼10% decrease in AMF (∼6% less precipitation), causes the system to transition from a wet climate ...

Impact of Raman Scattering on SIF Retrievals From Hyperspectral Satellite Observations

open access: yesGeophysical Research Letters, Volume 52, Issue 15, 16 August 2025.
Abstract Solar‐induced chlorophyll fluorescence (SIF) retrieved from spaceborne measurements is widely used as an indicator of vegetation activity. However, this weak emission can be confused with the inelastic scattering component of sunlight that lacks distinctive Fraunhofer lines.
