Sea ice thickness (SIT) is an important parameter in the study of climate change. During past 20 years, satellite altimetry has been widely used to observe sea thickness. The Chinese Haiyang-2B (HY-2B) radar altimeter, launched October 2018, can provide data up 80.6° latitude and be as a supplementary means polar ice. Reliable HY-2B SIT products will contribute community. In this study, we aime...

Short-range ocean forecast and reanalysis systems routinely combine observations from satellite altimetry, satellite sea surface temperature (SST), and in situ temperature and salinity, to initialise global and regional ocean models. The most critical observation type for eddy-resolving applications is arguably satellite altimetry. To quantify the impact of satellite altimetry observations on a...

Abstract. Coastal Inundation is the amount of water levels that reach above normal level due to flooding in coastal areas. This natural phenomenon rising local sea level. study aims develop a inundation simulation along coastline Terengganu. To ensure success this study, rate and magnitude rise are calculated using Radar Altimetry Database System (RADS) from multi-mission satellite altimetry da...

Spaceborne radar altimeters provide information on the Earth's surface by transmitting a series of radio-frequency pulses and recording their echoes. Although the beamwidth of the instrument is typically more than a degree, a finer ground footprint is achieved by only recording the return within a narrow window. Geophysical information on the sub-surface pixel is then derived from analysing the...

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...

The capability of satellite radar altimeters to monitor the height changes of major lakes is well established. However, river systems present far more challenging targets. By retracking altimeter echoes using an expert system approach, river heights can be successfully monitored; this capability is bounded by the along-track sampling rate. However, a glimpse into the potential of future altimet...
