The TanDEM-X mission will derive a global digital elevation model (DEM) with satellite SAR interferometry. Two radar satellites (TerraSAR-X and TanDEM-X) will map the Earth in a resolution and accuracy with an absolute height error of 10m and a relative height error of 2m for 90% of the data. In order to fulfill the height requirements in general two global coverages are acquired and processed....

Satellite laser altimetry has been widely used for monitoring surface height changes in inland waters. However, constructing time series of water levels is partially limited temporal resolution only based on the individual orbit altimeter observations. To densify and optimize altimetry-based crucial to scientific understanding lake hydrologic dynamics. This paper focuses synthesizing multi-orbi...

Monitoring large bodies of water, such as the Laurentian Great Lakes in North America, can be challenging and costly. The bathymetry, diffuse attenuation coefficient for downwelling irradiance ( Kd ), particulate backscattering xmlns:xlink="http://www.w3.org/1999/xlink">bbp</sub...

Forest structure is a useful proxy for carbon stocks, ecosystem function and species diversity, but it not well characterised globally. However, Earth observing sensors, operating in various modes, can provide information on different components of forests enabling improved understanding their variations thereof. The Ice, Cloud Elevation Satellite (ICESat) Geoscience Laser Altimeter System (GLA...

Abstract. Advances in geodetic altimetry instruments are providing more accurate measurements, thus enabling satellite missions to produce useful data for narrow rivers and streams. Altimetry spatially dense land water surface elevation (WSE) measurements remote areas where situ scarce that can be combined with hydraulic and/or hydrodynamic models simulate WSE estimate discharge. In this study,...

Canopy metrics from ICESat/GLAS lidar waveforms were applied to estimate stemwood volume for a mixed temperate forest. Gaussian decomposition from product GLA14 was used to infer a ground surface return from within the waveform. The region of the waveform returned from the vegetation was subsequently taken to be between this position and the beginning of the waveform signal. The heights of vege...

The Shuttle Radar Topographic Mission (SRTM) digital elevation data provides near-global coverage at about 90 m resolution and in much of the world is now the best available topographic data. Its application for quantitative analysis is limited by random noise and systematic offsets due to vegetation. This paper describes a multiscale Kalman smoothing algorithm for removing vegetation effects a...
