In this version of ATRIP, we provide the 1.0 degree and 0.5 degree global flow direction map.
In this version of TRIP2, we provide the 1.0 degree and 0.5 degree global flow direction map.
Note: In the flow direction map, the longitude values were saved from "small to big". The latitude values were saved from "big to small".

Missing value is -9999.
"9" implies that no outlet from that grid point. It could be a river mouth or an inland depression.

You can build a flow direction map with different resolution and for different regions by yourself. Some "rules" for the flow direction map that you should follow are listed below:
