Expanded Low-resolution Cloud Motion Winds - MFG - Indian Ocean 57 degrees E - Reprocessed

Vectors at all heights below the tropopause, derived from the Meteosat First Generation (MFG) IR channel by tracking the motion of clouds. The MFG low resolution 80x80 segment matrix (with 32x32 pixel segments) is used and vectors are derived by tracking the motion of clouds only; height assignment is based on IR EBBT. Before 2 December 2002 the ELW product derived vectors from all three MFG channels. A typical ELW product contains about 2000 IR vectors.
