Updated: 2004 Oct 28 1343 UTC Data from 59 real-time stations over the CORS network were used for these calculations.

Product generated by a data assimilation model driven by CORS ground-based GPS data.
Model resulted from a Space Weather Prediction Center - National Geodetic Survey collaboration.

The US-TEC product includes maps over the Continental US (CONUS) of

the vertical total electron content (TEC)
an estimate of the uncertainty in the map
the recent trend based on the departure of the TEC from the previous 10-day average
ACSII Data files of the vertical and slant path TEC

The slant path data files specify the line-of-sight electron content to the GPS satellites in view at the time. This ionospheric product is designed for estimating the signal delay for single and dual frequency GPS applications. Note that TEC values in regions outside of the CONUS have no data and should be treated with caution.

US Total Electron Content Real-time Specification is an experimental product. Evaluation will begin Nov. 1, 2004 and last until Mar. 22, 2005. We encourage your comments or suggestions for improvements using the electronic survey provided. Your feedback will help us determine product utility, if modifications are needed, and whether the product should become part of our operational suite. Feedback Form
