Matrix Export Output

All spatially distributed models in AirWare produce their output as MatrixObjects.

These matrices can be exported in CSV format using the export button at the details model results display page.

The exported CSV file starts with 16 lines of header information with the META data describing the exported matrix:

    Source CAMx
    Resolution 1000 m
    Substance NOx
    Unit ug/m3
    Start time 2008-08-25 19:00
    Duration 24 hours
    Interval 1 hour
    Time steps 24
    Layers 1
    Components 1
    Rows 300
    Columns 300
    Domain name TEHRAN
    NW corner of domain (UTM coordinates) x=380000 m - y=4105000 m
    Domain extent in x direction 300000 m
    Domain extent in y direction 300000 m

This is followed by the data ( comma separated floats ) for each grid cell.

For each time step the matrix is given in the following format (time steps are separated by an empty line):

  • Data start at the north-west corner of the domain.
  • Each line corresponds to a row of the matrix containing values ordered from west to east:
    • The first value corresponds to the north-west corner of the domain,
    • The last value of the first line corresponds to the north-east corner.
    • The first value of the last line corresponds to south-west corner of the domain,
    • The last value of the last line corresponds to the south-east corner.
