  • The Improved Stratospheric and Mesospheric Sounder (ISAMS) measured vertical profiles of temperature and a number of atmospheric constituents. An instrument on board UARS (Upper Atmosphere Research Satellite) measured global stratospheric and mesospheric temperature, CO, H2O, CH4, O3, HNO3, N2O5, NO2, N2O and aerosol extinction. Gridded, global measurements between 80S and 80N, October 1991 - July 1992. Data include level 2 and 3A product (gridded in time or latitude along the satellite track). Data are version 9/10 for Level 3 and version 8 for Level 2. ISAMS data is public.

  • The ACES (Aerosol Coupling in the Earth System) project was an integrated research programme that aims to reduce uncertainties in our fundamental understanding of the formation of BSOA (Biogenic Secondary Organic Aerosol) and the subsequent impact on atmospheric composition, through coordinated chamber studies, field studies, process model development, and application of atmospheric models of chemistry and transport to assess coupling and feedbacks in the Earth system. This dataset contains measurements of concentrations of dust particles of specific sizes at ground level below the rain forest canopy. Data were collected for the period 9-23 July 2008 by the University of Manchester scanning mobility particle sizer (10-1000nm) based at the forest in-canopy site located at the FACE (Forests Absorbing CO2 Emissions) nursery at the Sabahmas Estate oil plantation in Malaysia.

This dataset contains measurements of concentration of different sized particles, measured from ground level up to 32 metres. Data were collected for the period 13 April to 23 July 2008 by the University of Manchester GRIMM optical particle counter based at the forest in-canopy site located at the FACE (Forests Absorbing CO2 Emissions) nursery at the Sabahmas Estate oil plantation in Malaysia. Measurements were made at fixed heights of ground level, 8 metres, 16 metres, and 32 metres. Measurements were also taken whilst the instrument was mounted on a winch which had a height range of 1 metre to 28 metres.

The dataset contains measurements of concentrations of aerosols between 50nm and 2nm, using a TSI Condesation Particle Counter model 3025A, near ground level below the rainforest canopy at the nursery site. These data were collected from the 9th to 23rd of July 2008 by the University of Manchester condensation particle counter based at the forest in-canopy site located at the FACE (Forests Absorbing CO2 Emissions) nursery at the Sabahmas Estate oil plantation in Malaysia.

  • HIRDLS was a mid-infrared limb-scanning radiometer (21 channels from 6.12 to 17.76 µm and provided sounding observations to observe the lower stratosphere with improved sensitivity and accuracy. HIRDLS was carried on the Aura mission, part of the A-train procession of polar orbiting satellites forming part of NASA's Earth Observing System (EOS). This dataset contains level 2 version 7.00 data of the global distributions of temperature, clouds, aerosols, and 10 trace species O3, H2O, CH4, N2O, NO2, HNO3, N2O5, CFC11, CFC12, and ClONO2 in the stratosphere and upper troposphere at high vertical and horizontal resolution in the Earth's atmosphere between about 8 and 100 km, from the High Resolution Dynamics Limb Sounder (HIRDLS) instrument.

This dataset contains measurements of mixing ratios of NO, NO2, NOX, and O3, using different gaseous precursors and concentrations. The following precursors were used: Alpha-pinene, Beta-caryophyllene, Isoprene, Limonene, Linalool, Myrcene at the following concentrations: 30 parts per billion, 50 parts per billion, 250 parts per billion

  • The ESA Climate Change Initiative Aerosol project has produced a number of global aerosol Essential Climate Variable (ECV) products from a set of European satellite instruments with different characteristics. This dataset comprises monthly images of Absorbing Aerosol Index (AAI), using the Multi-Sensor UVAI algorithm, Version 1.4.7. For further details about these data products please see the linked documentation.

  • The Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) was a joint-mission between NASA and the French space agency Centre National d'Etudes Spatiales. The main objectives of the mission was to supply unique data set of vertical cloud and aerosol profiles. This dataset contains cloud and aerosol lidar level 2 vertical feature mask version 3-30 data product describes the horizontal and vertical distribution of the cloud and the aerosol layers observed by the Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP). Version 3-30 was released in April, 2013. This version incorporates two ancillary input files updated from those used in versions 3-01 and 3-02: GEOS-5 processing system version 5.9.1 from version 5.2; and the enhanced Air Force Weather Authority (AFWA) Snow and Ice Datasets. The resulting changes are relatively small.
