Figure 4.12. Normbeis3 input and output files for BEIS v3.14

Normbeis3 input and output files for BEIS v3.14

Figure 4.12, “Normbeis3 input and output files for BEIS v3.14” shows the input and output files for the Normbeis3 program for BEIS v3.14. The input files are the emission factors file (B3FAC), the gridded land use file for the first 120 land use types (BELD3_A), the gridded land use types for the next 110 types (BELD3_B), and the land use totals data file (BELD3_TOT).

Figure 4.13. Normbeis3 input and output files for BEIS v3.61

Normbeis3 input and output files for BEIS v3.61

Figure 4.13, “Normbeis3 input and output files for BEIS v3.61” shows the input and output files for the Normbeis3 program for BEIS v3.61. The input files are the emission factors file (B360FAC), the gridded land use file for the first 286 land use types (BELD4).

Figure 4.14. Normbeis3 input and output files for BEIS v3.7 or later version

Normbeis3 input and output files for BEIS v3.7 or later version

Figure 4.14, “Normbeis3 input and output files for BEIS v3.7 or later version” shows the input and output files for the Normbeis3 program for BEIS v3.7 or later version. The input files are the emission factors file (BEISFAC), the gridded land use file for the land use types (BELD5).

Normbeis3 outputs a gridded, normalized biogenic emissions file (B3GRD) and a log file (LOGFILE).

4.12.3.1. Input Files

Gridded land use data can be created using GIS software, such as ArcInfo. Another tool that can be used to generate gridded land use data is the SMOKE Tool in Models-3 (see Models-3 documentation). The typical database used to generate the BELD3_A, BELD3_B, and BELD3_TOT files is the BELD3. Future versions of SMOKE may include a method for creating land use files for use with Normbeis3.
