GRIB2 - GRID TEMPLATE 3.41

 
Rotated Gaussian latitude/longitude

Created 07/29/2005


Octet Contents
15-72 Same as grid definition template 3.40 (see Note 1)
73-76 Latitude of the southern pole of projection
77-80
Longitude of the southern pole of projection
81-84
Angle of rotation of projection


Notes:

1. Basis 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, the 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.

3. See Note (2) under grid definition template 3.1 ― rotated latitude/longitude (or equidistant cylindrical, or Plate Carree).
