Post processed value of the wind from direction in 10m altitude. Calculated according to: WIND_DIR=( pi/2 - atan(V_10M/U_10M)) * 180/pi for U_10M < 0 WIND_DIR=(3pi/2 - atan(V_10M/U_10M)) * 180/pi for U_10M > 0 WIND_DIR=180 for U_10M = 0 and V_10M > 0 WIND_DIR=0 for U_10M = 0 and V_10M < =0 Note: WIND_DIR=0 even if there is no wind. For this parameter the transformation procedure from the rotated grid (D2) to the regular grid (D3) is bilinear interpolation (cdo genbil, cdo remap).

Description
Due to technical reasons in data stream 2 (D2) the last record of every year was released with the time step(00.00 Hour, 01.January) of the following year in the netCDF header. The output of data stream 3 (D3) is not affected by this problem.
