The 2006/07 and 2007/08 US-ITASE traverses from Taylor Dome to South Pole in East Antarctica provided opportunities to survey the subglacial and englacial environments using 3MHz and 200MHz radar. We present first results of these new ground-based radar data. A prominent basal deformation layer indicates different ice-flow regimes for the northern and southern halves of the Byrd Glacier drainag...

Since turbid waters make it extremely difficult for light to penetrate the water column due attenuation, performing satellite-derived bathymetry using spectral images and/or photon-counting lidars is a very challenging problem in waters. The lidar borne on Ice, Cloud, and Land Elevation Satellite-2 (ICESat-2) can obtain high-resolution accurate height estimations of sea surfaces, that do not de...

The spatiotemporal sampling differences between ground-based and satellite lidar data can contribute to significant errors for direct measurement comparisons. Improvement in sample correspondence is examined by the use of radiosonde wind velocity to vary the time average in ground-based lidar data to spatially match coincident satellite lidar measurements. Results are shown for the 26 February ...

Abstract. Information about sea ice surface topography and related deformation is crucial for studies of mass balance, modeling, ship navigation through the pack. The Ice, Cloud, land Elevation Satellite-2 (ICESat-2), part National Aeronautics Space Administration (NASA) Earth Observing System, has been on orbit over 4 years, sensing with six laser beams capable capturing individual features su...

High-latitude lakes are sensitive indicators of climate change. Monitoring lake dynamics in high-latitude regions (e.g., pan-Arctic regions) is essential to improving our understanding the impacts change; however, lack situ water level measurements limits comprehensive quantification hydrologic regions. Fortunately, newly launched ICESat-2 laser altimeter can provide finer footprint and denser ...

The launch of NASA's Ice, Cloud, And Elevation Satellite-2 (ICESat-2) in September 2018 provides the scientific community an opportunity to observe high-resolution and three-dimensional surface elevations with global coverage. ICESat-2's Land Vegetation Height (ATL08) data product focuses on along-track terrain canopy heights observations at a 100 m × 11 spatial resolution. This work expands pa...

Continuous large-scale mapping of forest canopy height is crucial for estimating and reporting carbon content, analyzing degradation restoration, or to model ecosystem variables such as aboveground biomass. Over the last years, spaceborne Light Detection Ranging (LiDAR) sensor specifically designed acquire structure information, Global Ecosystem Dynamics Investigation (GEDI), has been used extr...
