Constraining Atmospheric Methanethiol Estimates Over the Southern Ocean

open access: yesGeophysical Research Letters, Volume 52, Issue 18, 28 September 2025.
Abstract Dimethyl sulfide (DMS) and methanethiol (MeSH) are biologically co‐produced marine volatile sulfur compounds, which play a critical role in climate‐cooling aerosol formation. The spatio‐temporal distributions of MeSH are poorly constrained, especially over the Southern Ocean.

Defining the Agricultural Wet Season in Africa Using Soil Moisture From the Soil Moisture Active‐Passive Satellite

open access: yesGeophysical Research Letters, Volume 52, Issue 18, 28 September 2025.
Abstract The wet season is commonly defined based on daily precipitation accumulation, which represents water inputs but does not account for losses from evaporation, infiltration, and runoff. Here, we estimate root‐zone soil moisture using observations from the Soil Moisture Active Passive (SMAP) satellite to capture year‐to‐year variations in ...

Applying the Dark Target Aerosol Algorithm with Advanced Himawari Imager Observations During the KORUS-AQ Field Campaign [PDF]

open access: yes
For nearly 2 decades we have been quantitatively observing the Earth's aerosol system from space at one or two times of the day by applying the Dark Target family of algorithms to polar-orbiting satellite sensors, particularly MODIS and VIIRS.

Going Off Grid: A Comparative Study of the Lagrangian and Eulerian Perspectives of New Particle Formation Events

open access: yesJournal of Geophysical Research: Atmospheres, Volume 130, Issue 18, 28 September 2025.
Abstract New particle formation and growth (NPF&G) is the process by which ultrafine particles are formed from gas‐phase precursors. NPF&G is the dominant source of global aerosol number with important influences on climate. Most observations of NPF&G events are conducted at stationary sites; however, NPF&G observed from stationary sites is influenced ...

TEMPO Aerosol Optical Depth and Aerosol Layer Height Retrieval Algorithm

open access: yesJournal of Geophysical Research: Atmospheres, Volume 130, Issue 18, 28 September 2025.
Abstract We developed an aerosol optical depth (AOD) and aerosol layer height (ALH) retrieval algorithm for Tropospheric Emissions: Monitoring of Pollution (TEMPO), the first geostationary sensor for monitoring air pollution over North America by enhancing state‐of‐the‐art algorithms originally developed for polar‐orbiting satellites to generate a ...
