Geoscience Australia contributes to Sentinel -4, -5 and -5p validation
Satellite instruments require ground-based measurements against which they can be calibrated and their products validated. This is as true for meteorological satellites as it is for the Copernicus Sentinels.
Geoscience Australia, the Australian public geoscience organisation, has installed and deployed a pair of spectrometers capable of measuring concentrations of trace gases in the Earth’s atmosphere (such as sulphur dioxide, ozone and nitrogen dioxides).
Data provided by these instruments supports validation of the measurements made by several of the Copernicus Sentinels.
The data contributes to the Pandonia network.
