Abstract
Abstract. The advancement of satellite altimeter technology has generated many evolutions to oceanographic and geophysical studies. A multi-mission satellite altimeter consists with TOPEX, Jason-1 and Jason-2, ERS-2, Envisat-1, CryoSat-2 and Saral are extracted in this study and has been processed using Radar Altimeter Database System (RADS) for the period of January 2005 to December 2015 to produce the sea surface height (hereinafter referred to SSH). The monthly climatology data from SSH is generated and averaged to understand the variation of SSH during monsoon season. Then, SSH data are required to determine the localised and new mean sea surface (MSS). The differences between Localised MSS and DTU13 MSS Global Model is plotted with root mean square error value is 2.217 metres. The localised MSS is important towards several applications for instance, as a reference for sea level variation, bathymetry prediction and derivation of mean dynamic topography.
Highlights
Over the past years, the progression of satellite altimeter has been tremendously improved
According to Peacook and Laxon (2004), the satellite altimeter has been used in the measurement of the time invariant component of sea surface height or mean sea surface, on a global basis
This study aims to determine the mean sea surface (MSS) for Malaysian Seas
Summary
The progression of satellite altimeter has been tremendously improved. Majumdar and Bhattacharyya (2005) stated that satellite altimeter measures the instantaneous sea surface height at the nadir with good precision. According to Peacook and Laxon (2004), the satellite altimeter has been used in the measurement of the time invariant component of sea surface height or mean sea surface, on a global basis. The Mean Sea Surface (MSS) is an essential and important product of satellite altimeter for supporting to oceanographic and geophysical studies (Hwang et al, 2002). It is the time-averaged physical height of the ocean’s surface. The comparison of the new localised MSS model with global model the quality of this new MSS by various validations is defined
