Important notice concerning CXML wind speeds from NCEP and CMC ensembles
Wind speeds given in CXML files from NCEP and CMC have units of knots.
CXML files for dates through 21 Oct 2010 (20101021) incorrectly specify that the wind speeds are given in m/s when in fact the correct units are kt.
A correction was made on 22 Oct 2010. The wind speed units are now correctly specified as kt.
