Analysis and Interpretation of Density and Wind Data

  • Eelco Doornbos
Part of the Springer Theses book series (Springer Theses)


The previous chapter already provided several figures and tables, illustrating results of the density and wind processing algorithms. These output data will now be analysed more closely. The various data sets will be plotted in various ways, compared with each other and with output from models, and interpreted in terms of geophysical signals and error sources.
