Description
Sentinel-3 is a polar-orbiting satellite completing 14 orbits of Earth daily. It carries five instruments for optical, temperature, radar, and microwave measurements of marine and terrestrial surfaces. The satellite was launched in 2016, with data available from July 2017 onwards from the European Commission's Copernicus programme.
Use Cases
Monitor ocean color and phytoplankton based on OLCI instrument data
Analyze sea and land surface temperature trends based on SLSTR instrument measurements
Measure sea surface height and ice topography based on SRAL radar altimeter data
Study atmospheric water vapor and cloud properties based on MicroWave Radiometer (MWR) observations
Track precise satellite orbit for geophysical studies based on Precise Orbit Determination (POD) data
Strengths
Data is collected from five distinct instruments providing multi-spectral measurements
Provides global coverage with 14 daily orbits since its operational phase began in 2017
Operational data stream is available from a major Earth observation programme (Copernicus)
