Chinese-French Oceanography Satellite (CFOSAT), the first satellite which can observe global ocean wave and wind synchronously, was successfully launched On 29 October 2018. The CFOSAT carries SWIM that on a scale. Based National Data Buoy Center (NDBC) buoys Jason-3 altimeter data, this study evaluated accuracy of L2 level products from August 2019 to September 2020. results show nadir Signifi...

Abstract The Origins, Spectral Interpretation, Resource Identification, and Security–Regolith Explorer (OSIRIS-REx) spacecraft spent more than 2 yr characterizing near-Earth asteroid (101955) Bennu. OSIRIS-REx Laser Altimeter (OLA) was responsible for producing the most accurate reconstruction of asteroid’s surface—down to a global resolution around 5 cm with data precision ±1.25 cm. However, b...

The variability of the trend of the global mean sea level (GMSL) on decadal scales is of great importance to understanding the long-term evolution of the GMSL. Trend determination is affected by the temporally correlated processes in the record, which have often not been properly accounted for in previous studies. The problem is treated here as one of optimal estimation weighted by the auto-cov...

The wind/wave climatology for the Arctic Seas will be developed based on altimeter observations. It will have a major scientific and applied significance as presently there is no reference climatology for this region of the ocean available. The new versions of wave models for the Beaufort and Chukchi Seas will include new physics that is already under development, and the novel physics presentl...

High-resolution altimetric data define the detailed topography of the northern lowlands of Mars, and a range of data is consistent with the hypothesis that a lowland-encircling geologic contact represents the ancient shoreline of a large standing body of water present in middle Mars history. The contact altitude is close to an equipotential line, the topography is smoother at all scales below t...

In the present work, geophysical model func[ions (GMFs) for altimeter wind speed measurements are described. These GMFs account for an effect of [he actual degree of sea development on the radar cro~ section by utilizing information on the significant wave height. The wind speed mertsurement accuracy achieved (the overall bias 0.1 m/s and the rms error about 1.6 m/s) is higher than the accuracy...

A full-spectral third-generation ocean wind-wave model, Wavewatch-III, has been implemented in the South China Sea (SCS) for investigating wind-wave characteristics. This model was developed at the Ocean Modeling Branch of the National Centers for Environmental Prediction (NCEP). The NASA QuickSCAT data (0.258 resolution) 2 times daily were used to simulate the wind waves for the entire year of...
