Glazman, Roman E.; Greysukh, Alexander, 1993, "Satellite Altimeter Measurements of Surface Wind", https://hdl.handle.net/2014/35442, IGARSS '93 Proceedings, JPL Open Repository
In the present work, geophysical model functions (GMFs) for altimeter wind speed measurements are described. These GMFs account for an effect of the actual degree of sea development on the radar cross section by utilizing information on the significant wave height. The wind speed... |
