Capability Demonstration of a JEDI‐Based System for TEMPO Assimilation: System Description and Evaluation

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 5, May 2026.
Abstract The launch of the Tropospheric Emissions: Monitoring of Pollution (TEMPO) mission in 2023 marked a new era in air quality monitoring by providing high‐frequency, geostationary observations of column NO2 across most of North America. In this study, we present the first implementation of a TEMPO NO2 data assimilation system using the Joint ...

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

Environment and Behavior, 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. Nearly 70% of the residents living within the flight corridors reported

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 APPROACH NOISE TRIALS

Inter-Noise 2022, 2023
This article presents the results from a series of aircraft approach trials that were conducted with the aim to investigate noise reduction procedures within the boundaries of a normal ILS approach. The significant decline in air traffic at Stockholm Arlanda, that occurred during the pandemic meant that the empty airspace and the availability of ...

Aircraft noise and psychiatric morbidity

Psychological Medicine, 1973
SynopsisAn earlier investigation which showed that admission rates to a psychiatric hospital were higher from the higher noise zones close to Heathrow Airport than from relatively quieter areas was repeated. The present paper could not confirm those results, although a trend in agreement with the original findings was found.

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.

Aircraft Noise and Incidence of Hypertension

Epidemiology, 2007
An association between aircraft noise exposure and hypertension prevalence has been suggested but there are no longitudinal studies of this association. Our aim was to investigate the influence of aircraft noise on the incidence of hypertension.A cohort of 2754 men in 4 municipalities around Stockholm Arlanda airport was followed between 1992-1994 and ...

Aircraft Noise

Noise & Vibration Worldwide, 2003
Various noise measurement parameters/indices used to define aircraft and airport noise are explained. The noise zone limits used around airports in some countries are given. Noise prediction software can be used to generate noise contours around airports.
