MCIP METCRO2D units - Wind Direction


The wind direction variable (WDIR10) in the MCIP file “METCRO2D” is reported in degrees. Is this the trigonometric reference, where East is 0 degrees and North is 90 degrees (increasing counterclockwise)?
Or is it the meteorological reference, where North is 0 Degrees and East is 90 degrees (increasing clockwise)?

Is there a standard in the meteorological modelling and measurement community?

Thank you,

Standard practice in meteorology (or so I am told) is 0 means from the north, 90= from the east, 180= from the south, and 270= from the west.
