AERONET
AERONET (AErosol RObotic NETwork) is a federation of ground-based aerosol networks established by NASA and the French PHOTONS program in 1993, operating robotically controlled sun photometers worldwide.
Aeronomy of Ice in the Mesosphere
Aeronomy of Ice in the Mesosphere (AIM) was a NASA satellite launched in 2007 to study noctilucent clouds; it operated 16 years, far beyond its planned two, until 2023.
Aeroperú Flight 603
Aeroperú Flight 603 was a Lima-to-Santiago Boeing 757 flight that crashed into the Pacific in 1996, killing all 70 aboard, after taped-over static ports left false instrument readings.
Aerophone
Aerophone: class 4 of the Hornbostel-Sachs (1914) instrument classification, instruments sounding mainly by vibrating air, free (accordion, harmonica) or non-free (flutes, reeds, brass); also Roland's digital wind instrument line.
Aeroplan
Aeroplan is the frequent-flyer loyalty program of Air Canada, founded in 1984, spun off in 2005, bought back in 2019, and relaunched in November 2020 with no fuel surcharges on flight rewards.
Aeroponics
Aeroponics: soilless growing of plants with roots suspended in air and misted with nutrient solution. Developed with NASA funding in the 1980s; used for space experiments and fivefold seed potato production gains; ROI 3–7 years commercially.
Aeroporti di Roma
Aeroporti di Roma is the Italian company, founded in 1974 and controlled by Mundys, that manages Rome's Fiumicino and Ciampino airports under a concession to 2044.
Aeroports de la Côte d'Azur
Aéroports de la Côte d'Azur (ACA) is a French airport operating company managing the Nice Côte d'Azur, Cannes Mandelieu, and Golfe de Saint-Tropez airports on the French Riviera.
Aeroports de Paris
Aéroports de Paris, also known as Groupe ADP, is the French listed company operating Paris-Charles de Gaulle, Orly, and Le Bourget, with 26 airports in 17 countries carrying 363.7 million passengers in 2024.
AeroPress
AeroPress: manual coffee brewer invented by engineer Alan Adler, introduced at Coffee Fest Seattle in November 2005. Combines immersion, paper micro-filtration, and plunger-driven air pressure for fast single-cup brewing; home of the World AeroPress Championship.
AeroScope
AeroScope was a DJI drone-detection system, unveiled in 2017, that identified and tracked DJI drones by passively monitoring their radio links; it was discontinued in 2023.
Aerosinusitis
Aerosinusitis, also called barosinusitis or sinus squeeze, is sinus mucosal injury from un equalized ambient pressure change during flight, diving, or hyperbaric exposure; frontal pain and epistaxis are leading symptoms.
Aerosmith
Aerosmith is an American hard rock band formed in Boston in 1970 by Steven Tyler and Joe Perry. Known for Toys in the Attic, Walk This Way, the Run-D.M.C. collaboration, and a 1980s comeback; over 70 million albums sold.
Aerosmith (album)
Aerosmith (1973) is the Boston hard rock band's self-titled debut on Columbia, recorded at Intermedia Studios; includes Dream On and Mama Kin, reissued as the 2026 Legendary Edition.
Aerosol
An aerosol is a suspension of solid or liquid particles in a gas, usually air, ranging from smoke and dust to sea salt and volcanic ash.
Aerosol and Chemistry Model Intercomparison Project
The Aerosol and Chemistry Model Intercomparison Project (AerChemMIP) was a set of CMIP6 climate model experiments quantifying the climate and air quality impacts of aerosols and chemically reactive gases.
Aerosol indirect effect
The aerosol indirect effect is the change in Earth's radiation balance caused when airborne particles modify clouds, a cooling that is the most uncertain climate forcing.
Aerosol jet printing
Aerosol jet printing (AJP) is a maskless, non-contact additive manufacturing technique that aerodynamically focuses ink droplets to print 10–50 µm electronic features on curved and flexible substrates.
Aerosol mass spectrometry
Aerosol mass spectrometry is the real-time measurement of the size-resolved chemical composition of airborne particles, a central tool of atmospheric chemistry and organic aerosol source apportionment.
Aerosol optical depth
Aerosol optical depth (AOD), also called aerosol optical thickness, is a unitless measure of sunlight extinction by aerosols, with values above 1.0 indicating heavy loading.
Aerosol-assisted chemical vapor deposition
Aerosol-assisted chemical vapor deposition (AACVD) is a thin-film deposition method in which precursor solutions are atomized and carried to a heated substrate, so precursors need only be soluble, not volatile.
Aerosol-cloud interaction
Aerosol-cloud interaction is the process by which atmospheric aerosol particles alter cloud microphysics, radiation, and precipitation, assessed by the IPCC as the largest single uncertainty in near-term climate projections.
Aerosonde
The Aerosonde is a small robotic fixed-wing unmanned aircraft for inexpensive environmental observation and surveillance, known since 1998 for long-endurance meteorological sampling and flights into tropical cyclones.
Aerospace
Aerospace is the industry and engineering field covering vehicles that fly in Earth's atmosphere and in space, combining aeronautics and astronautics, spanning aircraft, missiles, satellites, and other space vehicles.
Aerospace engineering
Aerospace engineering is the branch of engineering that designs, tests, and operates aircraft and spacecraft, combining aeronautical engineering for atmospheric flight and astronautical engineering for space flight.
Aerospace industry in the United Kingdom
The aerospace industry in the United Kingdom is the world's second-largest aerospace sector, contributing £13.6 billion to the economy in 2024 and employing around 113,000 people.
Aerospace Lithium (Hangtian Lithium)
Aerospace Lithium (Hangtian Lithium) is a Chinese battery manufacturer founded in 2020 in Gaoyou, Jiangsu, producing large cylindrical lithium iron phosphate cells including 38121 and 46950 formats.
Aerospace manufacturer
An aerospace manufacturer, also called an aerospace manufacturing company, is a firm that designs and builds airplanes, spacecraft, missiles, and their engines and parts under regulation.
