vars_N2Otier2: vars_N2Otier2
In emissions: What the package does (short line)

Description Details Author(s) References See Also Examples

This is a data.frame that allows you to input data on land areas of differet land use/land cover types and/or amounts of emitting substances. In other words, this data frame contains quantities of emission sources, dissagregated to the user's desired level based on the specificity of emission factors available.

This data frame is nearly identical to vars_N2Otier1, except that it is expected that the user will want to enter data representing a greater level of disaggregation of sources compared to the tier1 methodology. As such, you will notice that this example data frame has the same column headers (emission source types) as vars_N2Otier1, except each type is repeated with an 'A' and a 'B', representing one level of disaggregation. You may wish to disaggregate their sources to arbitrary levels, and therefore should modify this data frame (and EF_N2Otier1) accordingly. As with the tier 1 functions, it is a requirement that for any column header in vars_N2Otier2, there must be a matching column header in EF_N2Otier2. For details on the specific meaning of input data (column headers) in this table, please refer to the help file for vars_N2Otier1.
