(Abstract): These data are results from the KAMM/WASP
studies for Ethiopia. The KAMM/WAsP methodology uses a set of wind classes to represent wind conditions for the mapped region. A mesoscale simulation for each wind class, using KAMM (Karlsruhe Mesoscale Model), is performed and statistics performed on the model output. The results are a summary of the simulated wind climate, and ii.a wind atlas, a summary of the wind climate standardized to flat,
uniform roughness terrain.
(Purpose): The product is intended to be used to estimate the wind resource potential in the country including the spatial variability. This map covers regions where long term measurements are not available. In a sense this is the point of the mapping exercise, but it also means that verification of results has not been as complete would be ideal. There is some concern that the results may underestimate the resource. However, new measurement data is coming and revisions to the map may be made if necessary as verification is carried out.
(Supplemental Information): This is a short description of the files in this directory. The four data files are as follows.
1) AtlasDataETH_f_z50.10.wrm.u_i.ASC. This file contains the simulated annual mean wind speed [m/s] at 50 m a.g.l. over the terrain as
described in the mesoscale model.
2) AtlasDataETH_f_z50.10.wrm.e_i.ASC. This file contains the simulated annual mean wind power density [W/m^2]
at 50 m a.g.l. over the terrain as described in the mesoscale model.
3) AtlasDataETH_f_z0.10.wam.u_i.ASC This file contain the generalize annual mean wind speed [m/s] at 50 m a.g.l. over the flat terrain and uniform roughness of 0.03 m.
4) AtlasDataETH_f_z0.10.wam.e_i.ASC This file contains the generalized annual mean wind power density [W/m^2] at
50 m a.g.l. over the flat terrain and uniform roughness of 0.03 m.
