Added the section called “Lambert azimuthal equal area”.

the section called “Polar stereographic”: Added latitude_of_projection_origin map parameter.

Section 5.7, “Scalar Coordinate Variables”: Added note that use of scalar coordinate variables inhibits interoperability with COARDS conforming applications.

Example 5.11, “Multiple forecasts from a single analysis”: Added positive attribute to the scalar coordinate p500 to make it unambiguous that the pressure is a vertical coordinate value.

Section 7.3, “Cell Methods”: Changed several incorrect occurances of the cell method "standard deviation" to "standard_deviation".

Added Example 5.7, “Lambert conformal projection”.

the section called “ Atmosphere hybrid height coordinate ”: Fixed definition of atmosphere hybrid height coordinate.

Added the section called “Azimuthal equidistant”.

Added the section called “ Atmosphere natural log pressure coordinate ”.
