Global biological nitrogen fixation from 1900 to 2100

Global biological N fixation from 1900 to 2100 (yearly rate and 10-year rates per file) as estimated using a global land model (CABLE) with two different approaches (A1 and B1) for N fixation. Check out "readme.txt" for further information.\nA NCL script for plotting is also provided.\nLineage: These data were produced using CABLE with a model of biological N fixation (see Wang et al. 2007, Global Biolgoehcmical Cycles, 21, GB1018,doi:10.1029/2006GB002797) under the historical climate, N deposition and CO2 concentration from 1901 to 2005, and RCP8.5 scenarios of climate, N deposition and CO2 concentration from 2006 to 2100.
