From February 14, 2000 to August 1, 2002, daily air samples were collected in Toronto and Vancouver to study the chemical composition of PM 2.5 and co-pollutants. The study, led by the Meteorological Service of Canada, aimed to investigate sources, formation, and potential health effects of fine particles. Data includes particle size, chemical content, and the presence of gaseous co-pollutants like NO2 and O3.
Four automatic weather stations collected air temperature, soil temperature, wind speed, and solar radiation data along a 370-meter altitudinal gradient on Mt Elder, Macquarie Island. The dataset underpins a climate change scenario study that analyzed 50 years of temperature data and made forecasts to 2030. Data was collected by the Australian Antarctic Data Centre (AU_AADC) and last updated in July 1999.
458 vertical profile files from two research vessels in October 1980 capture salinity, temperature, and velocity.

The data was produced by the NARSTO/EPA partnership, with filters extracted and compounds analyzed via gas chromatography-mass spectrometry. The study aimed to characterize PM composition and sources in Southeastern Texas and support health effects research.
August and September 2000 air quality measurements collected at 85 continuous ambient monitoring stations in Texas during the TexAQS2000 study. The dataset contains 5-minute readings for pollutants like CO, SO2, NOx, ozone, PM2.5, and meteorological variables including wind, temperature, and humidity. It was produced by the Texas Commission on Environmental Quality and partners under the NARSTO program.
Six-beam Doppler radar data from a 1999 Atlanta air quality experiment measured vertical wind profiles. The University of Alabama-Huntsville Mobile Integrated Profiling System collected this data from July to September 1999 using a 915 MHz radar with 41 range gates and 55-minute consensus averaging. This dataset was part of the EPA's Particulate Matter Supersites Program to test measurement techniques and study atmospheric particle processes.
NARSTO_ICARTT_NEAX_2004_DOE_G-1_DATA contains air chemistry, aerosol, and meteorological measurements collected by the DOE Gulfstream G-1 aircraft during the 2004 ICARTT/NEAX campaign. The data were gathered on 13 flights over approximately 300 nautical miles from Latrobe, PA between July 19 and August 15, 2004, and are reported at 1-second and 10-second intervals. This dataset was produced by the NARSTO partnership and is hosted by the National Aeronautics and Space Administration.
NARSTO_PAC2001_CASSIAR_TUNNEL_GAS_PM_DATA contains gaseous and particulate matter measurements from the Cassiar Tunnel in British Columbia, Canada. Data was collected from August 8-15, 2001 by the North American Research Strategy for Tropospheric Ozone (NARSTO) partnership to reduce uncertainty in mobile source emissions inventories. The study was part of the larger Pacific 2001 Air Quality Study conducted in the Lower Fraser Valley.
12 hourly reports of upper air data were collected globally from March 1962 to December 1972. The National Meteorological Center (NMC) operationally gathered radiosonde, pibal, and aircraft reports via the Global Telecommunications System (GTS). This data served as primary input for NMC's modeling and forecasting and for major reanalysis projects.
Volcaniclastic polygons published by the Department of Energy, Environment and Climate Action on data_gov_au. The dataset was last updated on 2026-04-09 04:00:03.548456. It likely contains vector polygon features representing volcaniclastic deposits or related geological formations.
