The first IONEX map refers to 00:00 UT, the last map to 24:00 UT (instead of 01:00 and 23:00 UT, respectively). The time spacing of the maps (snapshots) is still 2 hours. Due to the fact that each new daily file contains ionospheric information covering not only 22 but 24 hours, data interpolation becomes much more user-friendly. This change concerns not only our final product (delivered to the CDDIS data center) but also our rapid and predicted IONEX products (made available through the CODE data base). Note that we hereby comply with a coordinated model change within the IGS ionosphere community. Best regards, Stefan Schaer ----------------------------------------------------------------------- How does the Earth's ionosphere currently develop? Look at http://www.aiub.unibe.ch/ionosphere/
