This document outlines data requirements and methodology of spectral analysis applicable to station-based, model-based and satellite-based ionospheric data. The DISPEC analysis will provide new high-level data applicable in correlation analyses, modeling and other Scientific Data Applications (SDA) tasks. The report includes a very preliminary round of processing with example data, demonstrating spectral analysis workflow. The parameters applied in this demonstration are unadjusted, and the figures have a preview character.
