Towards operational assimilation of surface‐sensitive microwave radiances over land at Environment and Climate Change Canada: Investigation of key factors using a 1D‐EnVar framework

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The study evaluates five factors affecting the assimilation of surface‐sensitive Advanced Microwave Sounding Unit‐A (AMSU‐A) radiances over land, including the simultaneous estimation of surface emissivity and the standard set of state variables, to improve numerical weather prediction (NWP) at Environment and Climate Change Canada (ECCC).

Ocean Meanders Modulate Extratropical Cyclone Energetics

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Extratropical cyclones primarily develop over the western parts of ocean basins, where strong sea surface temperature (SST) contrasts form along western boundary currents. While previous studies have highlighted the influence of the mean SST and SST gradient on cyclones developing over these currents, they have generally disregarded their ...

Long‐Range Transport Pathways of Intense Wildfire Plumes in the Northern Hemisphere Observed by the IASI/METOP Satellite Mission

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract Wildfires emit significant greenhouse gases and pollutants. Extreme fires disperse smoke plumes over long distances, necessitating a deeper understanding of their source regions and variability. This study introduces a plume back‐trajectory algorithm using carbon monoxide (CO) and peroxyacetyl nitrate satellite observations from the Infrared ...

A Comparative Study on the Irrigation Suitability of Kerala's Rivers Using Fuzzy AHP and Conventional Methods

Irrigation and Drainage, Volume 75, Issue 2, Page 815-839, April 2026.
ABSTRACT Food security in Kerala depends on effective irrigation, but poor‐quality irrigation water poses threats such as salinity, sodicity and reduced soil productivity. Although past assessments have been localised, this study presents the first comprehensive, statewide evaluation of irrigation water suitability across 44 major rivers in Kerala.

Distribution, Formation, and Evolution of Subsurface Secondary Acoustic Ducts From Global Ocean Modeling and Observations

Journal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract Monthly mean reanalysis from assimilating global ocean circulation models spanning 27 years is used to study subsurface secondary acoustic ducts, which provide waveguides for the transmission of mid‐frequency sound. A systematic diagnosis of secondary ducts from monthly mean temperature and salinity fields characterizes their distribution and ...

Spatializing energy justice

Energy Policy, 2017
This paper introduces the concept of spatial justice and inequality to understandings of energy poverty and vulnerability. By applying an explicitly spatial lens to conceptualize energy poverty as a form of injustice, it contributes to debates in the domain of ‘energy justice’, where previous examinations of energy deprivation through a justice framing
