Unprecedented Carbon Accumulation in the Indian Ocean During 2016–2017

open access: yesGeophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract During 2016–2017, the Indian Ocean experienced a pronounced increase in dissolved inorganic carbon (∼0.39 PgC/yr), approximately four times greater than the annual mean air–sea CO2 flux. Using a reconstructed data product and a state‐of‐the‐art ocean biogeochemical model, we attribute this anomaly to an enhanced Southern Ocean inflow and a ...

Hourly Precipitation Intensities at 4‐km Resolution Show Statistically Significant Increasing Trends From 1991 to 2022 in the CONUS‐404 Hydroclimate Reanalysis

open access: yesGeophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract Trends in hourly and daily precipitation statistics are studied using the CONUS‐404 hydroclimate reanalysis at 4‐km spatial resolution over the 1991–2022 period. Only a small fraction of CONUS shows statistically significant trends in the annual precipitation volume, number of wet days and mean wet‐day intensity.

Linking Very Near‐Earth Reconnection (VNERX) to Mid‐Latitude GICs: Evidence From the 7 September 2017 Storm

open access: yesGeophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract Geomagnetically Induced Currents (GICs) are a hazard to power systems. In this letter, we present a case study to understand why a Sudden‐Commencement‐associated 20A GIC spike, measured at mid‐latitude in Virginia, US, increased to 30A within 2 min of interplanetary shock arrival.
