ODIAC version 2013a global high resolution fossil fuel CO2 emission dataset (ODIAC2013a)


1) Data format

Dimension  = 43200 (n of columns) x 21600 (n of rows)
Data type  = Float
Byte order = Little endian
Unit       = Tonne Carbon/cell/month 

2) Coordinate definition

The emission fields are defined on a geographical (longitude and latitude) coordinate system.  Longitude and latitude can be calculated as follows: 

Lon (i) = -180 + dx/2 + dx x i (i=0,43199)
Lat (j) =  90 + dy/2 + dy x j (j=0,21599)

where dx = dy = 30 arc-seconds (0.008333333333333 degrees or approximately 1km).
