SPC Geoscience Division

Pacific Island Countries are generally surrounded by large areas of ocean over which clouds easily build up within the lower atmosphere with increasing altitude. The micro-climate of the moisture-laden lower atmosphere is very inhomogeneous and can distort images captured by optical satellites. An atmospheric correction is therefore important in order to enhance image data. Beginning in 2011, atmospheric correction software has started to incorporate the digital elevation model to reduce relief related atmospheric disturbances.

The Applied Geoscience and Technology Division of SPC is the hub of satellite image data purchase within the region, and the Division also enhances the image data for Pacific users including the application of an atmospheric correction. SOPAC therefore maintains a working relationship with global software developers adjusting software specifically for Pacific conditions.
