Hi,<div><br></div><div>I am using GrADS 2.0.a9 and need to use tcorr in a specific way. Whilst the use of tcorr is relatively simple (correlating two spatial parameters over time), I would like to correlate a spatial parameter (example U-wind across the globe) with the time series of a station like value (ex. the NAO index). The station values I have are at the moment stored in excel format but I can easily convert them to text such as the attached file.</div>
<div><br></div><div>What I need to know is the format of the station data I have to prepare (and if necessary how, unless its a common procedure) and how to tell GrADS to do what I need using tcorr or something similar. </div>
<div><br></div><div>I do not want one value but a spatial correlation plot.</div><div><br></div><div>Regards,</div><div><br></div><div>James</div>
