This option specifies the number of refinement levels in a VAPOR data approximation hierarchy . Starting with where the native grid resolution , of each successive level in the hierarchy is a factor of two smaller finer along each dimension. If level is 0 no hiearchy hierarchy will be created (all data will be stored at their native resolution). If level is 1 a single approximation will be created, thus the hierarchy will have two levels: the first approximation (indexed as 0 in VAPOR) and the native grid resolution , and the first approximation(indexed as 1 in VAPOR). And so on.
The default value is: 2.
