Section 3 - Template 42 : Stretched Gaussian latitude/longitude

Octets Key Type Content
15-72 Same as Grid Definition Template 3.40 (see Note 1)
73-76 latitudeOfThePoleOfStretching signed Latitude of the pole of stretching
77-80 longitudeOfThePoleOfStretching signed Longitude of the pole of stretching
81-84 stretchingFactorScaled unsigned Stretching factor
85-nn pl unsigned List of number of points along each meridian or parallel (These octets are only present for quasi-regular grids as described in note 4)
Notes:

( 1) Basic angle of the initial production domain and subdivisions of this basic angle are provided to manage cases where the recommended unit of 10-6 degrees is not applicable to describe the extreme longitudes and latitudes, and direction increments. For these last six descriptors, unit is equal to the ratio of the basic angle and the subdivisions number. For ordinary cases, zero and missing values should be coded, equivalent to respective values of 1 and 106 (10-6 degrees unit).

( 2) The number of parallels between a pole and the equator is used to establish the variable (Gaussian) spacing of the parallels; this value must always be given.
