| Description | These are simulated river gauge data that are derived from Jason-2 and Envisat altimetric measurements. The purpose of this dataset is to provide hydrological altimetric measurements and to get the hydrology community accustomed to using satellite hydrology data before SWOT launches. |

| Platform/Sensor | ENVISAT / Platform Name: Environmental Satellite (ENVISAT) Orbit Period: 100.59 minutes Inclination Angle: 98.55 degrees Ascending Node: 1970-Jan-01 00:00:00 RA-2 SENSOR Name: Radar Altimeter 2 (RA-2) Swath Width: 5 km Description: Nadir pointing radar altimeter measuring at 13.575 GHz (Ku band) and 3.2 GHz (S band) OSTM/JASON-2 / Platform Name: Ocean Surface Topography Mission/Jason-2 (OSTM/JASON-2) Orbit Period: 112.43 minutes Inclination Angle: 66.04 degrees Ascending Node: 1970-Jan-01 00:00:00 POSEIDON-3 SENSOR Name: OSTM/Jason-2 RADAR alitmieter (POSEIDON-3) Swath Width: 5.1 km Description: The Poseidon-3 altimeter, operating at 13.575 GHz (Ku band) and 5.3 GHz (C band), is the primary sensor for the OSTM mission. The measurements made at the two frequencies are combined to obtain measurements of the altimeter range, wind speed, significant wave height, and the ionoshperic correction. The Poseidon-3 package consists of dual redundant altimeter units each of which has low mass and low power consumption. |
