| Description | The Global Lake/Reservoir Surface Inland Water Height Time Series is derived from the G-REALM10 lake level product https://ipad.fas.usda.gov/cropexplorer/global_reservoir/ The purpose of this dataset is to provide surface water dynamics for several hundred lakes and reservoirs across the globe. These time series potentially span a 25 year time period, from late 1992 to 2017, satisfying the project goal of ESDR creation with a suitable level of quality that supports long-term trend analysis and global water dynamics models. Water level variation is also a key component required for the determination of surface water storages and fluxes. This product is readily accessible and is of direct use to both water managers and the scientific community worldwide, and allows for improved assessment and modeling of the human impact on the global water cycle. |

| Platform/Sensor | 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. |
