  • The Cloud_cci ATSR2-AATSRv3 dataset (covering 1995-2012) was generated within the Cloud_cci project, which was funded by the European Space Agency (ESA) as part of the ESA Climate Change Initiative (CCI) programme (Contract No.: 4000109870/13/I-NB). This dataset is one of the 6 datasets generated in Cloud_cci; all of them being based on passive-imager satellite measurements. This dataset is based on measurements from the ATSR2 and AATSR instruments (onboard the ERS2 and ENVISAT satellites) and contains a variety of cloud properties which were derived employing the Community Cloud retrieval for Climate (CC4CL; Sus et al., 2018; McGarragh et al., 2018) retrieval framework. The core cloud properties contained in the Cloud_cci ATSR2-AATSRv3 dataset are cloud mask/fraction, cloud phase, cloud top pressure/height/temperature, cloud optical thickness, cloud effective radius and cloud liquid/ice water path. Spectral cloud albedo is also included as experimental product. The cloud properties are available at different processing levels: This particular dataset contains Level-3C (monthly averages and histograms) data, while Level-3U (globally gridded, unaveraged data fields) is also available as a separate dataset. Pixel-based uncertainty estimates come along with all properties and have been propagated into the Level-3C data. The data in this dataset are a subset of the ATSR2-AATSR L3C / L3U cloud products version 3.0 dataset produced by the ESA Cloud_cci project available from https://dx.doi.org/10.5676/DWD/ESA_Cloud_cci/ATSR2-AATSR/V003.

  • The objective of the ADIENT (Appraising the Direct Impacts of aErosol oN climaTe) project was quantifying the direct effect of aerosols on the Earth's radiation budget, via scattering and/or absorption of radiation. This monthly data is a subset of the GlobAEROSOL climatology from the Along Track Scanning Radiometer (ATSR) instrument on-board ERS-2, data. It spans the period 1 July 1995 to 10 July 2009. The dataset contains measurements of the following parameters over the globe: Aerosol optical thickness due to aerosol Angstrom Coefficient average, Aerosol speciation (from a selection of 5 pre-defined types:maritime, continental, desert, urban/polluted and biomass burning).

  • The objective of the ADIENT (Appraising the Direct Impacts of aErosol oN climaTe) project was quantifying the direct effect of aerosols on the Earth's radiation budget, via scattering and/or absorption of radiation. This daily data was a subset of the GlobAEROSOL climatology from the Advanced Along Track Scanning Radiometer (AATSR) instrument on-board Envisat, data for the period 24 July 2002 to 25 February 2009. This dataset contains measurements of the following parameters over the globe: Aerosol optical thickness taken at 550nm and 870nm, Angstrom Coefficient, Earth surface albedo taken at 550nm, 670nm, 870nm, and 1600nm. Upwelling spectral radiance in the air (measured reflectance) at 550nm, 670nm, 870nm, 1600nm, and 3700nm. Brightness temperature taken at 11000nm and 12000nm. Cloud area fraction Aerosol speciation (from a selection of 5 pre-defined types:maritime, continental, desert, urban/polluted and biomass burning).
