MERIT-DrainAttr: Baseline drainage attributes for the global 90 m drainage network

Four baseline drainage attributes of the global 90 m MERIT Hydro drainage network (22.2 billion land pixels): flow length downstream, flow length upstream, Strahler stream order, and upstream drainage area. These are the standard outputs of flow-routing kernels, computed with the topological structures of the companion record MERIT-FlowTopo (doi:10.5281/zenodo.20653059) and released as ready-to-use rasters. Derived from MERIT Hydro (Yamazaki et al., 2019; doi:10.1029/2019WR024873), not redistributed here.

Global upstream drainage area is already distributed with MERIT Hydro, so it is not duplicated here. See MERIT-DrainAttr_README.md for full documentation.
