SOCAT: decimation also consider time delta #1737

Open karlmsmith opened 6 years ago

karlmsmith commented 6 years ago

Reported by @karlmsmith on 9 Mar 2016 23:03 UTC I notice that for some moorings the decimated data only consists of a couple of points. The longitude and latitude do not change, so under the current decimation scheme only significant changes in fCO2 triggers a new point, and apparently the changes in fCO2 for mooring are pretty small.

Seems like there should also be point at least every 6 hours in the decimation scheme. I suggest this time step because the coarsest decimation in SOCATv2, which was only on time, was every 6 hours and resulted in a much smaller set of points.

Is this something that could be added to the decimation scheme?
