Multisensor Validation of Ers-1 Sar Wave Mode and Altimeter-derived Significant Wave Heights Using Topex, Geosat and Seasat Data
A comparison of signiicant wave heights H s was performed using satellite altimeter data available between 1978 to 1994 from SEASAT, GEOSAT, ERS-1 and TOPEX. The purpose was to estimate the degree of accuracy between the diierent instruments. Statistical properties of H s as obtained from the altimeters are found to be compatible with those from in situ measurements in the North Atlantic. All H...
متن کاملEffect of High-Frequency Sea Waves on Wave Period Retrieval from Radar Altimeter and Buoy Data
Wave periods estimated from satellite altimetry data behave differently from those calculated from buoy data, especially in low-wind conditions. In this paper, the geometric mean wave period is calculated from buoy data, rather than the commonly used zero-crossing wave period . The geometric mean wave period uses the fourth moment of the wave frequency spectrum and is related to the mean-square...
متن کاملSelection of Remotely Sensed Data
An increasing number of sensors are available for forest ecologists and managers seeking to map attributes of forest canopy cover, forest structure and composition, and their dynamics. This Chapter seeks to put these advances within the context of the needs of forest managers and scientists. To do so, we review the basic physics behind a variety of imagery types, discuss fundamental limitations...
متن کاملA Comparison of Two Altimeter Wave Period Algorithms Using Data from a N. E. Pacific Buoy
Two recent algorithms for estimating zero-upcross wave periods from altimeter data are investigated using data from a buoy in the North East Pacific with a relatively high occurence of swell. Both algorithms performed well in wind seas, with low wave age, but only one – developed using a neural network – was satisfactory when the wave age was high.
