I am learning that I need to ask better questions. This sea level rise seems significant right?
If the foot print of the altimeter is between 2km^2 and 11km^2, how many datapoints would you expect to find in the data?
I understand that summarized data is more useful for most people. I am uncomfortable when the line item data is not readily available. Let us just approximate on the short side how many data points there likely should be...
Google gets me 360,000,000 square km of ocean. At 11km^2 per point that makes 32,000,000 data points per pass. The time between revisiting each point is 9 hours. 1 year of data should then contain 3.6*10^13 lines of data.
30 years of data is quite a chunk.
Maybe it isn't quite possible to push that data to a server. ... Then again, maybe they aren't storing actual height measurements...
