Hello M.Sarika;
In XBuild, select 'Environment' from the main menu and pull-down for sub-menu and look for 'Environmental Modifications'. Here, you can add various CO2 conc. levels.

Hello,
For crop modeling , I need to provide DSSAT CERES-Rice model
with CO2 levels from different scenarios.
There appears to be an option in the File X simulation controls
to let CO2 be read from the weather file when the switch is set to
"W".However, looking through associated documentation (weather.cde,
DSSAT manuals, source code for CO2val.for), I don't see how one provides
CO2 as a variable in the .WTH file.I have tried entering a "CO2"
variable in a .WTH file also, but the model doesn't take it and
defaults to the 380 ppm value.
Thank you
