This is an atmospheric hourly hindcast for parts of the Atlantic and Africa using COSMO-CLM version 4.8_clm_11 with spectral nudging from 1979-2012 and ERAinterim forcing. The model uses a rotated grid with 540 x 350 grid points and a grid point distance of 0.14 degrees, the rotated North pole is located at 10 W, 75 N. In rotated coordinates the model area extends from 40 W to 35.46 E, 25 S to 23.86 N, in geographical coordinates this corresponds to about 50 W to 25 E, 35 S to 8 N.
