Template 4.59

Individual ensemble forecast control and perturbed interval for spatio temporal changing tile parameters deprecated point in time interval for spatio-temporal changing tile parameters

Notes:

(1)   The number of used tiles (NUT) is the number of used different spatial tiles, defining the cover structure of point. As each of these tiles has one or more different tile attributes A(NAT(ITN)), where (ITN=1,...,NUT), for example, (unmodified, snow-covered,...), there are NT=∑ITN=1NUT NAT(ITN) fields (that is, the total number of tile attribute pairs, defined in (octet 13) with indices (ITN,IAN) with the following meaning (IAN={1,...,ITN)}):     1,1                                    First tile - first attribute (e.g. unmodified) attribute     ...                           ...     1,NAT(1)                         First tile - NAT of first tile (last, e.g. snow-covered) attribute     2,1                                    Second tile - first attribute (e.g. unmodified)     ...                          ...     2,NAT(2)                         Second tile - NAT of second tile (last, e.g. snow-covered) attribute     ...                          ...     ...                          ...     NUT,1                             NUT tile - first attribute (e.g. unmodified)     ...                          ...     NUT,NAT(NUT)          NUT tile - NAT of last attribute (last) attribute

A single tile attribute index (ITN,IAN) with spatial tile index ITN(1,...,NUT) and attribute A(IAN) with (IAN=1,...,NAT(ITN)) is represented in the template. All NT partitions are linked by the normalization formula, which states that the sum of all partions must be equal to normalization term (N=1 for fractions and N = 100 for percentage) on each point of the grid.

The fields "tile class" and "tile fraction" must be provided in order to obtain the tile structure of each grid point. Please note that the field "tile fraction" is time-dependent in the case of defined attribute, whereas the field "tile class" is not affected by attribute (NT=NUT).
