A float-based Ocean color vicarious calibration program

Frontiers in Remote Sensing
Ocean color satellites require a procedure known as System Vicarious Calibration (SVC) after launch as the pre-launch and on-orbit calibration accuracy is insufficient.

Using Machine Learning to Uncover Ecological Mechanisms Controlling Abundance of Phytoplankton Size Classes From Large‐Scale Observations

Global Biogeochemical Cycles, Volume 40, Issue 4, April 2026.
Abstract Phytoplankton size classes (PSCs) and Phytoplankton functional types (PFTs) determine many fundamental biogeochemical processes including nutrient uptake, energy transfer through marine food webs, ocean carbon export, and gas exchange with the atmosphere. Discerning the causes of spatio‐temporal variability of PSCs is a scientific priority for

How Supply Networks Influence Sustainable Innovation: Evidence From Ghana's Public Works Procurement

Business Strategy and the Environment, Volume 35, Issue 3, Page 4309-4327, March 2026.
ABSTRACT Recent environmental and sustainability standards in procurement increase short‐term production and operational costs to suppliers, which are often recouped by charging price premiums for innovative solutions. However, public buyers are less likely to pay such price premiums, resulting in a disincentive among suppliers to bid for innovation ...

Consequences of Social Frontiers Segregation for Labour Income: Evidence From Oslo

Population, Space and Place, Volume 32, Issue 2, March 2026.
ABSTRACT We study the impact on earned income of living in neighbourhoods characterised by a special type of residential segregation, called social frontiers. Possible labour market outcomes of living in neighbourhoods marked by social frontiers have not been previously studied.

Algorithm Theoretical Basis for Version 3 TEMPO Level 0–1 Processor

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract The Tropospheric Emissions: Monitoring of Pollution (TEMPO) instrument is the first spaceborne hyperspectral spectrometer that measures backscattered sunlight over North America in a geostationary orbit. The two charge‐coupled device (CCD) detectors of TEMPO, with spectral coverages of 293–494 and 538–741 nm and resolutions of 0.53–0.63 nm ...
