Very Long Baseline Interferometry (VLBI) Earth Orientation Parameters (EOP) Products from NASA CDDIS
Listed in NASA Earthdata CMR
These derived data products are intensive (1-hour experiments) and series Earth orientation parameter (EOPI and EOPS, respectively) solutions obtained with Very Long Baseline Interferometry (VLBI).
Description
The CDDIS archive contains EOPI solutions provided by various analysis centers of the International VLBI Service for Geodesy and Astrometry (IVS). The VLBI EOP products include one for each Universal Time (UT1) intensive session with a minimum of one year of data.
The operational EOP products are available at IVS Data Centers 24 hours after the Intensive data become available.
