The Infrared Atmospheric Sounding Interferometer (IASI) methane dataset contains height-resolved and column-averaged volume mixing ratios of atmospheric methane (CH4). It also includes column-averaged water vapour (H2O), a scale factor for the HDO volume mixing ratio profile, surface temperature, effective cloud fraction, effective cloud-top pressure and scale factors for two systematic residual spectra which are jointly retrieved from the spectral range 1232.25-1290.00 cm-1. Also contains selected a priori values and uncertainties. Funded by NCEO.

Provides ocean colour products derived by merging satellite data from sensors MERIS, MODIS and SeaWiFS, after shifting the wavelength bands and correcting the bias among the sensors.

NCEO dataset of ozone profiles from radiances measured by the Global Ozone Monitoring Experiment (GOME) on-board the European Remote Sensing - 2 (ERS-2) satellite; includes total column ozone, column BrO, and column NO2, with cloud heights derived from the Along Track Scanning Radiometer (ATSR) included to aid interpretation of the ozone profiles.

This NCEO dataset contains cloud optical depth, aerosol optical depth (cloud free), cloud phase, cloud particle size, cloud top pressure, cloud fraction and cloud ice/water path along with associated error measurements. GRAPE aimed to produce a global cloud and aerosol dataset of the entire Along Track Scanning Radiometer 2 (ATSR-2) mission.

NCEO dataset of ocean properties estimated for 1998-2007 from the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) and SeaStar Level 3 data; includes Phytoplankton Size Class (1998-2007) calculated from SeaWiFS/SeaStar data and ocean optical properties and monthly climatology, 1998-2007 SeaWiFS/SeaStar data.
