520 |a"The objective of this work is to develop near-real time riometer data processing techniques, including data filtering and quiet day curve fitting to improve the accuracy of real-time riometer data. This report describes the algorithm NRCan has developed for processing riometer data in near-real time. In Section 2, riometer instruments used in the NRCan riometer array are described. The basic algorithm for near-real time processing of riometer data for operational use is described in Section 3. Section 4 explains how to identify periods where shortwave fadeout, auroral absorption, and polar cap absorption are expected to be observed in riometer data based on observed conditions. Identification of these periods is vital for modeling the quiet-day riometer response necessary for calculating absorption. Section 5 describes techniques for downsampling riometer data to calculate the quiet day curve, which is described and evaluated in Section 6. The methodologies described in this report form a robust data processing algorithm for handling real-time riometer data for operational use"--Introduction, page 2.
