The mean squared slope is a property of the sea surface that is often sensed by microwave radars [1] [2].

While spatial data for sea surface salinity, sea surface height, and significant wave height exist (Ex. [3] [4]), I've not been able to find spatial mean squared slope data, or wave spectrum data (from which mean squared slope can be derived). The only data I know of are from the National Buoy Data Center, but they are point measurements only.

I'm currently working on a microwave remote sensing project, and spatial mean squared slope data would prove to be helpful. Does anyone know if spatial mean squared slope or wave spectrum data exist anywhere?

    $\begingroup$ I can't help directly, but you may get better answers if you specify whether there's a particular part of the world that you're interested in (possibly US waters, since you link to NOAA?) or whether anywhere will do. $\endgroup$ Commented May 17, 2015 at 6:23
