DOGEx is designed to test automated offset detection algorithms against a known truth in the presence of realistic GPS timeseries signal, noise, offset frequency and gaps. DOGEx is a one-way blind experiment in that the actual offset times and magnitudes are not released with the site timeseries. The data set we supply is a simulated time series of daily NEU coordinates and the formal errors for 50 "sites". The experiment is being run jointly by Matt King (Newcastle University, Newcastle upon Tyne, UK; m.a.king@ncl.ac.uk) and Simon Williams (Proudman Oceanographic Laboratory, Liverpool, UK; sdwil@pol.ac.uk). The data set and further information may be found at http://www.cost-es0701.gcparks.com/working-groups/wg A poster will be presented at EGU in Vienna (session G3 Posters on Tuesday, 04 May 17:30-19:00). We look forward to hearing from you with solutions! Please circulate this email to other interested colleagues.
