I downloaded the data and I need to get the elevation values. The data contain different variables and now I am unable to select the right variable which will give me elevation.
Hi. If your data are in NetCDF format, you can read the files and extract variables with "ncread" function in MATLAB. The variables you need to calculate the water levels are "satellite altitude", "the distance between satellite and water surface (Range)", geophysical corrections such as "pole tide", "solid earth tide", "Sea State bias (for sea waters)", ... , media corrections such as "Wet tropospheric correction", "Dry tropospheric correction", "Ionospheric correction" and retracking correction that is done by algorithms. These corrections are added to the range and the corrected range is subtracted from the satellite altitude to find the water level.
Hi, firstly, you can download and install the BRAT program. after installing the program open the program and click an option and choose RADS to download cryosat2 data. the program can read downloaded data in NetCDF format.
finally, you can download the pdf "Radar Altimetry Tutorial" for more information.
