Concurrent Cloud and Drizzle Observations From Synergistic Ground‐Based Measurements

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Drizzle, a common feature of marine boundary layer clouds formed through collision‐coalescence, plays a key role in cloud microphysics and evolution. However, simultaneously retrieving cloud and drizzle properties from remote‐sensing observations remains challenging because drizzle droplets often dominate radar signals, masking cloud ...

Resolving Convective‐Scale Cloud and Precipitation Structures in Tropical Cyclone Rainbands With Novel Raman Lidar Observations

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Low‐level clouds in the tropical cyclone (TC) rainbands modulate the radial inflow of warm, moist boundary layer air, which can impact TC intensity. Yet, precisely measuring rainband cloud boundaries with existing remote sensing techniques remains a challenge.

Refining the Simulation of Mixed‐Phase Clouds Over Coastal Antarctica With a Tailored Ice Nucleating Particle Parameterization

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Climate models have substantial biases in downwelling shortwave radiation over the Southern Ocean (SO) and Antarctica, primarily due to their inability to accurately represent the frequent occurrence of low‐level mixed‐phase clouds. Building on the evaluation of the Unified Model (UM) Regional Atmosphere and Land version 3 (RAL3), this study ...

Aircraft noise immission modeling

CEAS Aeronautical Journal, 2019
This contribution to the CEAS special edition Aircraft Noise Generation and Assessment focuses on the simulation of the aircraft noise immission, i.e., the aircraft noise received on the ground. This process includes two steps, the description of the sound emission by the aircraft and the modeling of the sound propagation through the atmosphere.

Aircraft noise.

Technical documentary report. SAM-TDR. USAF School of Aerospace Medicine, 1998
A questionnaire distributed to two groups, one living within the flight pattern of a major airport and the other in a nonflight area, sought to determine whether these groups would respond differently to questions pertaining to noise, health perception, and quality of life issues.

Military aircraft noise

9th Propulsion Conference, 1973
Opportunities to reduce military aircraft noise without inhibiting mission capability are considered. Emphasis is placed on the need for a comprehensive military aircraft noise abatement program involving compatible land use in the vicinity of military airports, operational constraints, and procedures to reduce noise impact and source noise reduction ...

Masking of Speech by Aircraft Noise

The Journal of the Acoustical Society of America, 1966
Word-intelligibility tests at various intensity levels were administered to a crew of trained listeners in the presence of recorded noise from jet and propeller-driven aircraft. The noise was that which would be present outdoors and in a house as the result of engine runup operations and if aircraft were flying overhead shortly after takeoff and prior ...

Aircraft noise and birth weight

International Archives of Occupational and Environmental Health, 1981
Data from six infant welfare centres in the vicinity of Amsterdam airport were analysed. Birth weights of 902 infants were related to aircraft noise levels to which the mother was exposed in pregnancy. The analysis was restricted to deliveries in hospital, single births and mothers aged 20–34 years.
