To investigate this question in more detail, a pair of experiments using the U.S. Navy's NWP system is presented that compares the NRL superobbing procedure with the ECMWF thinning procedure. The NRL superobbing procedure collects AMVs from a particular satellite and channel in a prism that is 2° latitude by 2° longitude at the equator and averages the u and v components to form superobs only if the individual AMVs to be averaged are sufficiently similar. If they are not, an attempt is made to form a superob after rejecting one or two outliers; failing that, the prism is divided into quarters horizontally, and an attempt is made to form superobs within each quarter. The ECMWF thinning procedure simply selects the AMV with the greatest Quality Indicator (QI) value. The experiments are run using data after January 2012 so that hourly winds are available from all satellites and providers. Verification is done in comparison to both self-analyses and ECMWF analyses in addition to an evaluation of observation impact.
