APPENDIX D: FULL LISTING OF
NDP050.DAT (FILE 2)
The following is a full listing of ascii file ndp050.dat (File 2), which is
also provided, in binary
spreadsheet format, as file ndp050.wk1 (File 3). This
file lists the estimated net flux of carbon, in
units of 1000 Gg of carbon (1 gigagram = 109 g), to the atmosphere
from land-use change, from
1850 through 1990, by year and by region, along with the global totals. The
values in this listing
replace the values in files netflux.* in Houghton and Hackler (1995), the
previous version of this
database.
