2. USE OF DATA

These data are made freely available to the public and the
scientific community. Their wide dissemination
will benefit the society and lead to better understanding and new scientific insights.
If the data are obtained for potential use in a publication or presentation, 
Dr. Hanqin Tian should be informed at the outset of the nature of this work.  
If the data are essential to the work, or if an important 
result or conclusion depends on the data, co-authorship
may be appropriate. Manuscripts using the data should be sent to Dr. Hanqin Tian
for review before they are submitted for publication so we can
make sure that the quality and limitations of the data are accurately
represented.

3. DATA CONTENT

The variables include river discharge, and dissolved inorganic carbon (DIC).

The gridded datasets are in ASCII format at a spatial resolution of 5 arc-minute 
covering the period of 2010-2099. The datasets include:

(1) M1-A2-leachDIC: The spatial distribution of DIC leaching from land. The unit is g C/m2/year;
(2) M1-B1-leachDIC: The spatial distribution of DIC leaching from land. The unit is g C/m2/year;
(3) M2-A2-leachDIC: The spatial distribution of DIC leaching from land. The unit is g C/m2/year;
(4) M2-B1-leachDIC: The spatial distribution of DIC leaching from land. The unit is g C/m2/year;
(5) M3-A2-leachDIC: The spatial distribution of DIC leaching from land. The unit is g C/m2/year;
(6) M3-B1-leachDIC: The spatial distribution of DIC leaching from land. The unit is g C/m2/year.

Two csv. files include river discharge, and DIC export driven by three general circulation models (GCMs) 
under SRES A2 (high level) and B1 (low level) scenarios at the outlet of the MRB basin covering the period of 2010-2099:

(1) MRB-Discharge-future.csv: river discharge. The unit is km3/year;
(2) MRB-C-future.csv: DIC export. The unit is Gg-C/year.
