Simulations of data compression of satellite geophysical data

Data compression techniques are frequently discussed for data which are in the form of images. Some forms of geophysical data can be considered as matrices, similar to images. Results are shown of the effectiveness of several compression techniques on data from the plasma wave experiments flown on three scientific satellites. The use of actual data shows that an average telemetry bandwidth saving of a factor of two or three can be achieved without serious degradation. This saving can be used to increase the data quality, usually by way of improved resolution (either spectral or spatial), when regions of scientific interest are encountered.
