NASA’s Ice, Cloud, and land Elevation Satellite-2 (ICESat-2) provides exceptional opportunities for characterizing the structure of ecosystems through acquisition along-track, three-dimensional observations. Focusing on canopy cover as a fundamental parameter assessing forest conditions, overall goal this study was to establish framework generating gridded 30 m product with ICESat-2. Specifical...

There are an increasing number of digital elevation models (DEMs) available worldwide for deriving elevation differences over time, including vertical changes on glaciers. Most of these DEMs are heavily post-processed or merged, so that physical error modelling becomes difficult and statistical error modelling is required instead. We propose a three-step methodological framework for assessing a...

Water level fluctuations of inland lakes are related to regional-scale climate changes, and reflect variations in evaporation, precipitation and glacier meltwater flowing into the lake area in its catchment. In this paper, Ice, Cloud and land Elevation Satellite (ICESat) altimeter data and Landsat imagery (2002–09) are used to estimate Nam Co lake (Nyainqentanglha range, Tibetan Plateau) water ...

Spatially-detailed forest height data are useful to monitor local, regional and global carbon cycle. LiDAR remote sensing can measure three-dimensional forest features but generating spatially-contiguous forest height maps at a large scale (e.g., continental and global) is problematic because existing LiDAR instruments are still data-limited and expensive. This paper proposes a new approach bas...

The ICESat-2 Precision Orbit Determination (POD) system computes the precise position of laser altimeter instrument in inertial space, a measurement necessary for accurate geolocation individual photon surface returns. POD solutions are generated by reduction Global Positioning System (GPS) double-difference carrier phase observable residuals with NASA Goddard Space Flight Center's GEODYN softw...
