Improving the Intercalibration of σ 0 Values for the Jason-1 and Jason-2 Altimeters
The normalized backscatter from a radar altimeter, σ, is a measure of the surface roughness at scales of a few radar wavelengths; over the ocean this is used to infer wind speed. Long-term studies of wind speed rely on consistent measurements within an altimetric mission and good intercalibration between missions. For the Jason-1 and Jason-2 altimeters the derivation of σ from the full waveform...
متن کاملJason-1 / Jason-2 metocean comparisons and monitoring
The initial tandem phase of the Jason-2 mission is important for the calibration of the entire altimetric system, not just the records of sea surface height. However, as well as allowing a bulk comparison of metocean parameters such as wave height and backscatter strength (used to infer wind speed), it affords a more detailed opportunity to understand the artefacts within each instrument. The w...

In the pre-Internet era there was a significant time lag between the creation of a work by an author and the time a consumer read that work. The Internet has allowed authors to create and publish their work and disseminate across the world quickly. There has been an explosion of online content and publishing over the last decade. Most people believe that this trend is going to continue on a ste...
متن کاملOptimizing σ0 Information From the Jason-2 Altimeter
A radar altimeter's normalized backscatter, σ, is used in many oceanographic applications, to infer values of wind speed, wind stress, rain rate and the presence of biogenic slicks. The waveform retracker used to estimate the key geophysical variables for the altimeters on the Jason-1 and Jason-2 satellites shows increased small-scale variability since the problem is ill-conditioned. A simple e...
