****************************************************************************** BSW Electronic Mail 14-Nov-2002 19:10:02 CET Message Number 0153 ****************************************************************************** Author: Stefan Schaer Subject: CODE ionosphere product change Dear BSW users, The ionosphere model change as announced in IGS Mail 4162 http://igscb.jpl.nasa.gov/mail/igsmail/2002/msg00500.html also affects CODE's global ionosphere products made available in the Bernese ION file format. The software version 4.2 should be able to handle the new ION files. The main advantage of the new TEC parameter representation (based on piece-wise linear functions) is that discontinuities (specifically at the 2-hour interval boundaries) are no longer possible. Best regards, The BSW Team ----------------------------------------------------------------------- How does the Earth's ionosphere currently develop?
