I am doing a bit of analysis for an Indian Ocean crossing.  I'm using the ECWMF reanalysis data for wind.  I noticed that wave data is also available.  After running the multiple optimizations, using the analysis feature I am able to create the heat map for TWA vs. TWS.  Just wondering if there is a way to extract the Significant Wave Height and Wave Direction from the data sets in a similar fashion.  Could be really interesting.  Thanks.
