      Matrix META data

      In AirWare, all model related spatial data use the same, common data format and are described as matrix OBJECT.
      Matrix objects are read-only, they are generated by mode pre-processors or are model generated output. Matrix objects (which can contain one or more 2D matrices, usually: 24 hourly) are described by the foolowing set ofMETA DATA from the TABLE: AIRMATRX.MATRIX_METADATA. The example below provides an example directly from the data base:
