How are scatterometer observations standardised before being fed into reanalysis models?
EraIntroduction to Scatterometer Observations Scatterometers are active remote sensing instruments that measure the backscatter of electromagnetic radiation from the Earth’s surface. This backscatter is directly related to surface roughness, which in turn is influenced by factors such as wind speed and direction over the ocean. Scatterometer observations have become an invaluable tool in meteorology and
