Advanced Energy and Sustainability Research, Volume 7, Issue 3, March 2026.Hydrogen‐powered aviation offers a transformative pathway to zero‐emission flight by eliminating in‐flight CO2 emissions. Key considerations include propulsion systems (fuel cells and hydrogen combustion), cryogenic storage and insulation challenges, infrastructure and cost barriers, and supply‐chain constraints.

Properties of young contrails – a parametrisation based on large-eddy simulations [PDF]
Atmospheric Chemistry and Physics, 2016 Contrail–cirrus is probably the largest climate forcing from aviation. The evolution of contrail–cirrus and its radiative impact depends not only on a multitude of atmospheric parameters, but also on the geometric and microphysical ...

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 2, 28 January 2026.Abstract Line‐shaped contrails formed behind aircraft can evolve into broadly spread and long‐living cirrus clouds under favorable conditions. These contrail‐cirrus contribute significantly to the aviation‐induced radiative forcing. While past modeling studies have examined contrail‐cirrus across various atmospheric and aircraft‐type dependent ...

Formation of Hole Punch Clouds
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 1, 16 January 2026.Abstract Hole‐punch clouds (HPCs) are circular or oval cloudless holes in thin supercooled cloud layers. They are believed to be generated by aircraft passing through supercooled cloud layers; however, the exact formation mechanisms remain poorly understood due to the scarcity of observations.

Freshly Generated Super Sunrise Plasma Bubbles During the Geomagnetic Storm on November 5–6, 2023
Space Weather, Volume 24, Issue 1, January 2026.Abstract During the geomagnetic storm on November 5–6, 2023, freshly generated super sunrise equatorial plasma bubbles (EPBs) and associated irregularities over the 80°–140°E sector were observed combining ground‐based and space observations from GNSS, ionosondes, HF Doppler records, and several satellite missions (COSMIC2, Swarm, and DMSP).

Ground-based mobile scanning LIDAR for remote sensing of contrails [PDF]
Annales Geophysicae, 1994 Air traffic is a source of trace gases in the upper troposphere and lower stratosphere. Contrails readily form from water vapor exhausts under favorable meteorological conditions. Since contrails are ice crystal clouds like natural cirrus clouds, they

Dermoscopy in the Treatment Monitoring of Cutaneous Infectious Diseases: A Review
Dermatologic Therapy, Volume 2026, Issue 1, 2026.Dermoscopy represents a powerful, noninvasive tool for assessing both active infection and therapeutic resolution in a broad spectrum of infectious skin diseases. Despite the different causative agents (parasitic, viral, or fungal), it allows to identify characteristic pathogen‐associated structures at baseline and sequential morphological changes ...

Selected topics on the interaction between cirrus clouds and embedded contrails [PDF]
Atmospheric Chemistry and Physics, 2012 Persistent contrails and natural cirrus clouds often coexist in the upper troposphere and contrails can be embedded within cirrus clouds. The present paper deals with some questions regarding the interaction of cirrus clouds and embedded contrails.

Dermatologic Therapy, Volume 2026, Issue 1, 2026.Dermoscopy is a noninvasive tool that enables the visualization of skin lesions with magnification, allowing for more accurate diagnosis. Over the years, it has evolved from a utility in differentiation between malignant and benign neoplasms to administration in the vascular, inflammatory, and infectious dermatoses.
