Ammonia sources include agricultural activities, and its measurement aids in monitoring global atmospheric composition.
UAEMRMRD_005 is a regional summary of Multi-angle Imaging SpectroRadiometer (MISR) Level 1 radiance parameters averaged over a month for the United Arab Emirates region. The NASA MISR instrument uses nine cameras at different angles to measure radiance in four spectral bands (443, 555, 670, and 865 nm) to monitor aerosols, clouds, and land surface cover. This version 5 product reports data on a geographic grid with a resolution of 0.5 degrees.
Version 4 of the Multi-angle Imaging SpectroRadiometer (MISR) Level 3 Component Global Radiance Product for the United Arab Emirates region. It provides a daily statistical summary of top-of-atmosphere Bidirectional Reflectance Factor and spectral expansive albedos, gridded at a 0.5-degree by 0.5-degree resolution. The data is produced by the National Aeronautics and Space Administration and was last updated in March 2026.
A geospatial dataset defining groundwater protection reservation areas within the Mittelhessen planning region. The data originates from the Bundesamt für Kartographie und Geodäsie and is based on the Regional Plan Mittelhessen 2010, which outlines large-scale spatial development concepts for the Giessen administrative district. The dataset was last updated on March 31, 2026.
August-September 2000 continuous measurements of formaldehyde (HCHO) and hydrogen peroxide (H2O2) collected during the Texas Air Quality Study 2000 at the Houston Regional Monitoring Site 3. The dataset contains integrated 3-minute samples collected every 10 minutes. It was produced by the NARSTO EPA Supersite program to characterize particulate matter sources and support health effects studies.
NARSTO and EPA collected size-segregated particulate mass data using a MOUDI sampler during the 2000 Texas Air Quality Study. Daily sampling occurred from August 17 to September 13, 2000, at two monitoring locations in the Houston area. The study aimed to characterize fine particulate matter composition and sources to support health effects research.
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.
