Abstract. The Terrestrial Ecosystem Carbon Monitoring satellite will be the first of China with multi-beams laser altimeter and repetition frequency equal to GLAS on world altimetry ICESat, but smaller diameter than GLAS. This a milestone Chinese from single elevation control application multi-scene applications, such as forest height, water level measurement so on. In this paper, basic paramet...

SUMMARY The Ice, Cloud and land Elevation Satellite 2 (ICESat-2) laser altimetry mission, launched in September 2018, uses six parallel lidar tracks with very fine along-track resolution (15 m) to measure the topography of ice, ocean surfaces. Here we assess ability ICESat-2 data recover oceanographic signals ranging from surface gravity waves marine geoid. We focus on a region tropical Pacific...

Accurate measurements of terrain elevation are crucial for many ecological applications. In this study, we sought to assess new global three-dimensional Earth observation data acquired by the spaceborne Light Detection and Ranging (LiDAR) missions Ice, Cloud, Land Elevation Satellite-2 (ICESat-2) Global Ecosystem Dynamics Investigation (GEDI). For this, examined “ATLAS/ICESat-2 L3A Vegetation H...

Accurate bathymetric and topographical information is crucial for coastal marine applications. In the past decades, owing to its low cost high efficiency, satellite-derived bathymetry has been widely used estimate depth of shallow water in areas. However, insufficient spectral bands availability situ depths limit application bathymetry. Currently, investigation about potential hyperspectral ima...

Abstract Water diversion is crucial for maintaining sustainable development in populated lake areas. However, there has been no clear evaluation of how water affects health these areas, which are often limited by scarce situ observations. To address this issue, we selected Baiyangdian, a fragmented freshwater shallow Xiongan New Area, as our study area. We conducted time series analysis Baiyang...

The Ice, Cloud, and Land Elevation Satellite-2 (ICESat-2), launched in September 2018, has been widely used forestry surveying. A high-accuracy digital elevation model (DEM)/digital surface (DSM) for terrain matching can effectively evaluate the ICESat-2 design requirements provide essential data support further study. conventional terrain-matching methods regard laser ground track as a whole, ...

Abstract. We present a comparison of Ice, Cloud and land Elevation Satellite-2 (ICESat-2) geolocated photon heights operational ice charts from the Finnish Ice Service in Bay Bothnia spring 2019. show that ICESat-2 (IS2) retrievals areas with different ridging characteristics, more precisely degree (DIR), differ significantly. DIR is particularly useful parameter for navigators, as it provides ...
