The Chromospheric Solar Limb Brightening at Radio, Millimeter, Sub-millimeter, and Infrared Wavelengths

, 2016
Observations of the emission at radio, millimeter, sub-millimeter, and infrared wavelengths in the center of the solar disk validate the auto-consistence of semi-empirical models of the chromosphere.

Charge towards green finance ignores risks of nature commodification: Evidence from the UK's climate and nature recovery policy landscape

People and Nature, Volume 8, Issue 5, Page 1297-1308, May 2026.
Abstract The urgent need for up‐scaled finance has become central to the climate and nature recovery discourses worldwide. With most existing investments coming from public sources, closing the financing gap has become the overpowering argument for calling for private investments into nature restoration and conservation.

The Relation between the Radial Temperature Profile in the Chromosphere and the Solar Spectrum at Centimeter, Millimeter, Sub-millimeter, and Infrared Wavelengths

, 2014
Solar observations from millimeter to ultraviolet wavelengths show that there is a temperature minimum between photosphere and chromosphere. Analysis based on semi-empirical models locate this point at about 500 km over the photosphere.

Sharing the light, impact of solar parks on plant productivity, soil microbes and soil organic matter

PLANTS, PEOPLE, PLANET, Volume 8, Issue 3, Page 1000-1013, May 2026.
Solar parks enable renewable energy production at a large scale, thereby reducing greenhouse gas emissions. However, the effects of this change in land use on vegetation and soil health are still largely unknown. In this study, we determined the impacts of solar parks on vegetation, soil biota and soil carbon between and below solar panels.

Actualización del currículum en educación química: la importancia de la luz solar en nuestra vida [PDF]

, 2014
Els processos induïts per la llum solar són vitals per als éssers vius. La naturalesa ens demostra que els processos tèrmics i fotoquímics es complementen per donar lloc a molècules valuoses per als éssers vius.
