Notes: 1. Negative values associate to this coordinate will indicate depth below ground surface. If values are all below the surface, use of entry 106 is recommended with positive coordinate values instead. 2. The Eta vertical coordinate system involves normalizing the pressure at some point on a specific level by the mean sea level pressure at that point.
