A Common Reference Material for Mass‐Dependent Sn Isotope Compositions: An Inter‐Laboratory Calibration Approach

open access: yesGeostandards and Geoanalytical Research, Volume 50, Issue 2, Page 341-367, June 2026.
Key Points We recommend using the notation δ122/118SnNIST SRM 3161a for mass‐dependent Sn isotope data. We derived conversion factors relative to NIST SRM 3161a for Puri Sn CEZA (0.132 ± 0.011‰), Sn Lyon (0.229 ± 0.016‰), Sn IPGP (0.162 ± 0.018‰). Tin isotope compositions are presented for SPEX CertiPrep Sn and nine USGS reference materials.

Role of Future Climate Change, Air Pollution Control and Methane Mitigation in Driving Hydroxyl Radical (OH) and Methane Lifetime

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract The hydroxyl radical (OH) determines the atmospheric lifetime of many pollutants like methane (CH4 ${\text{CH}}_{4}$). This study isolates climate change, air pollution control and CH4 ${\text{CH}}_{4}$ mitigation effects on OH concentrations ([OH]) and CH4 ${\text{CH}}_{4}$ lifetime, by analyzing Coupled Model Intercomparison Project Phase 6 (

Toward Closing the Hydroxyl Radical (OH) Budget: Assessing the Feasibility and Uncertainties in Constraining primary OH Production From Space

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract Recent progress in constraining the atmosphere's primary oxidant, the hydroxyl radical (OH), with machine learning (ML) and satellite data raises the intriguing possibility of also constraining individual OH chemical production and loss terms.
