Estimating ocean climatologies for short periods: A simple technique for removing the effect of eddies from temperature and salinity profiles

摘要: [1] Existing temperature and salinity ocean climatologies are usually mean fields based on observations collected over many decades. Because of low frequency variability major features such as the Gulf Stream it is often more appropriate to define for shorter periods, but there subsequently fewer problems with aliasing mesoscale variability. We present a method removing eddy-related noise from using satellite altimeter sea surface height measurements. demonstrate technique Argo northwest Atlantic produce an eight year period. The reduction in variance achieved quantified. Comparison existing climatology shows that good agreement between two analyses representation realistic new climatology.
