Files in this archive are grid files exported using gridascii command in ArcInfo (signified by the ga_ prefix in file names).
Spatial extent = pantropic delineation
Resolution = 30-minute (0.5 dd) except where noted.
Projection = geographic

scenario1_delta_ro_allgrids = change in annual runoff (in mm/yr) between synthetic contemporary and original landcovers for all grid cells in pantropic.
scenario1_delta_ro_forgrids = change in annual runoff (in mm/yr) between synthetic contemporary and original landcovers for grid cells that were originally forested.
contemporary_q_km3pyr = long-term annual average basin yield or discharge (Q) in km3/yr resulting from contemporary landcover dataset.
original_lc_runoff_mm = annual runoff (in mm/yr) resulting from original landcover dataset.
synthetic_lc_runoff_mm = annual runoff (in mm/yr) resulting from synthetic contemporary landcover dataset.
original_q_km3pyr = long-term annual average basin yield or discharge (Q) in km3/yr resulting from original (pre-industrial) landcover dataset.
scenario2_delta_ro = change in annual runoff (in mm/yr) between contemporary and scenario 2 landcovers.
scenario2_delta_q = change in annual basin yield or discharge (in km3/yr) between contemporary and scenario 2 landcovers.  This was generated by flow accumulation of scenario2_runoff on the flow direction grid.
scenario2_dq2q_ratio = ratio of scenario 2 delta_q to contemporary_q.
scenario2_lc_runoff_mm = annual runoff (in mm/yr) resulting from scenario 2 landcover dataset.
