ISO 16698:2013 PDF

ISO 16698:2013 specifies the methods used for estimating geomagnetic indices for time intervals ranging from short-term (hours to a few months) to the long-term (months to years). Geomagnetic indices are used to describe the activity levels of the disturbance of the geomagnetic field. These indices can be used to estimate upper atmospheric and plasmaspheric densities and many other space environment models. They are also used as the input parameters for orbital lifetime prediction and worst-case environment analysis of electrostatic charging. ISO 16698:2013 is useful for users who want to predict future geomagnetic indices and space environment.
