BEC team offers a Singularity Analysis GUI. Processing is restricted to registered users (registration is free and completing it is a matter of seconds). Presently, there is no limitation in the amount of NetCDF files you can process, but a maximum number can be imposed in the future if we experience server overload.
Why should we be interested in such a mathematical, abstract concept? Because if a flow exhibits horizontal turbulence – and the ocean is a quasi-2D turbulent flow at scales greater that a few kilometers – singularity exponents derived from any ocean scalar are the same and, in fact, they represent the streamlines of the flow! (Turiel et al., Physical Review Letters, 2005; Isern-Fontanet et al, Journal of Geophysical Research, 2007; Nieves et al, Geophysical Research Letters, 2007; Turiel et al., Remote Sensing of Environment, 2008; Turiel et al., Ocean Science, 2009).
Since January 2013, daily maps of singularity exponents derived from OSTIA SST are available at our server. In response to some researchers’ need to compute the singularity exponents from their own datasets, we have created an experimental web service that allows users to compute the singularity exponents field from any input image saved in a NetCDF file, to visualize it (individually or fused with the original image) and to download the output image in NetCDF for its later use.
