Moist bias in the Pacific upper troposphere and lower stratosphere (UTLS) in climate models affects regional circulation patterns [PDF]

open access: yesAtmospheric Chemistry and Physics
Water vapour in the upper troposphere and lower stratosphere (UTLS) is a key radiative agent and a crucial factor in the Earth's climate system. Here, we investigate a common regional moist bias in the Pacific UTLS during Northern Hemisphere summer in ...

Three-dimensional tomographic reconstruction of atmospheric gravity waves in the mesosphere and lower thermosphere (MLT) [PDF]

open access: yesAtmospheric Measurement Techniques, 2018
Gravity waves (GWs) have been intensively studied over recent decades because of their dominant role in the dynamics of the mesosphere and lower thermosphere (MLT).

Midlatitude ClO during the maximum atmospheric chlorine burden : in situ balloon measurements and model simulations [PDF]

open access: yes, 2005
Chlorine monoxide (ClO) plays a key role in stratospheric ozone loss processes at midlatitudes. We present two balloonborne in situ measurements of ClO conducted in northern hemisphere midlatitudes during the period of the maximum of total inorganic ...

Recent Developments in Sustainable Composites for Printed Circuit Boards (PCBs): A Review

open access: yesMacromolecular Materials and Engineering, EarlyView.
This review presents the potential of using natural plant fibers and biodegradable polymers as sustainable printed circuit boards (PCBs). This review provides future directions in innovation and sustainable PCBs development. Bio‐composites PCBs are both environmentally friendly and sustainable due to the natural fibres they contain.

In-situ comparison of the NOy instruments flown in MOZAIC and SPURT [PDF]

open access: yes, 2006
Two aircraft instruments for the measurement of total odd nitrogen (NOy) were compared side by side aboard a Learjet A35 in April 2003 during a campaign of the AFO2000 project SPURT (Spurengastransport in der Tropopausenregion).

Environmental Impact Assessment of an Innovative Sustainable Thermoplastic Anticorrosion Coating for Aluminum Alloy AA2024

open access: yesPolymer Engineering &Science, EarlyView.
Life cycle assessment reveals that recyclable PPM coatings significantly reduce environmental impacts compared to epoxy, promoting sustainable aerospace corrosion protection. ABSTRACT This study evaluates the environmental performance of an innovative thermoplastic anticorrosion coating based on poly(phenylene methylene) (PPM) for aluminum alloy AA2024,

Morphology of the scattering target: Fresnel and turbulent mechanisms [PDF]

open access: yes, 1983
Further studies of VHF radar signals from the troposphere and stratosphere revealed not only scattering from isotropic turbulence at scales of half the radar wavelength but also partial or Fresnel reflection or scattering from horizontally stratified ...
