 | Earth's water cycle. Powered by the Sun, Earth's finite water supply is constantly circulated between the oceans, the atmosphere and the land. This circulation and conservation of Earth's water is a crucial component of our weather and climate.

| | | |  | The Surface Energy Balance System (SEBS) model of daily evapotranspiration estimates based on data from the Advanced Along-Track Scanning Radiometer (AATSR) on ESA's Envisat satellite. The AATSR images were acquired for 17 July 2004 during the SPARC-2004 (SPECTRA Barrax Campaign-2004) campaign.

| | | |  | This image is the first data sent to Earth by the MIRAS instrument on ESA's SMOS satellite, launched on 2 November 2009. It was acquired as part of the initial functional verification test since the instrument was switched on on 17 November. The image depicts non-calibrated brightness temperature values colour coded from blue (low) to red (high). Although the image content cannot be interpreted at this time, it proves that the instrument is in good shape and the data reception and processing chain are working.
