Extrapolate trend in gridded data - MathOverflow most recent 30 from http://mathoverflow.net 2013-05-24T12:55:55Z http://mathoverflow.net/feeds/question/78081 http://www.creativecommons.org/licenses/by-nc/2.5/rdf http://mathoverflow.net/questions/78081/extrapolate-trend-in-gridded-data Extrapolate trend in gridded data Anthony 2011-10-13T23:32:50Z 2011-10-13T23:32:50Z <p>I'm interested in extrapolating measured horizontal wind data of a vehicle into a forecast horizontal wind grid. Given the flight path you have a series of points that are "more accurate" than the forecast data. What would be the best way to extrapolate those deltas out into the neighboring points (especially in front of the vehicle), assuming the trends in the forecast data are likely to persist?</p> <p>I hope that was clear. I have a general idea of how I would do this, but I'm sure there's a name/algorithm for what I'm trying to do. Thanks!</p>
