Dear sir/ma'am, I am a bachelor of Survey Science and Geomatic student from Malaysia. This is my final year and I have to complete a research, where my research is about to evaluate marine gravity and satellite altimetry data on coastal region. 1. The problem statement, all variables and given/known data I am in the middle of processing a satellite altimetry data on coastal region. I am using basic radar altimetry tool software and using Jason2 satellite coastal product. The problem is I do not know what correction and formulas involve in this process. 2. Relevant equations 1) What is the formulas or correction can I use to put in the field expression to determine marine gravity anomaly using basic radar altimetry tool (BRAT) software? 2) What type of data in the 'dataset' should I choose for this process? 3. The attempt at a solution I have try to use SSHA data to execute the process, the result come out in error.
