Available in PDF, EPUB and Kindle. Book excerpt: During the 2- to 3-hr sunrise transition period, the relative change in foF2 is 20-60 percent per hour and is independent of solar activity. The change is largest in winter and smallest in summer. To prevent the skip distance from changing by more than 250 km, that is, to maintain continuous illumination of at least 50 percent of the barrier (nominal width 500 km), requires that the operating frequency be changed for every 6 percent change in foF2. Thus, in the case of an OTH system, the operating frequency has to be adjusted during the sunrise period every 6 to 20 min (seasonal dependence) for satisfactory performance. To accommodate such rapid changes, an empirical algorithm has been tested for improved foF2 predictions during sunrise. The prediction scheme is based on the availability of relevant (under the oblique raypath) real time ionospheric data.

Book Synopsis Improving the Global Ionospheric Predictions of F0F2 by : B. S. Dandekar
Download or read book Improving the Global Ionospheric Predictions of F0F2 written by B. S. Dandekar and published by . This book was released on 1976 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using the method of Rush and Gibbs (1973), weighted means of observed values have been used to update the global prediction of f(o)F2, which are based on monthly median values derived from the Institute of Telecommunications Sciences model (1969). This procedure improved the predictions for magnetically quiet periods, for times near minimum of the solar cycle phase, and for the equinoctial months. Furthermore, a closer grid of ionosonde stations resulted in reducing the error in the f(o)F2 prediction. For the method of Rush and Gibbs (1973) to be operationally successful in global predictions of f(o)F2 however, a closer grid of ionosondes than is presently available is needed. (Author).
