The brief message below came to me from:
Message for immediate release:

The Abdus Salam International Centre for Theoretical Physics, Trieste, Italy, has recently released a new web-based platform that aims to automate and simplify the use of an ionosphere model and the way to obtain TEC calibrated from GNSS.

The platform consists of two web services:

(1) The NeQuick 2 web model (Reference: Nava, B, Coisson, P, Radicella, SM (2008). "A new version of the NeQuick ionosphere electron density model", Journal of Atmospheric and Solar-Terrestrial Physics, 70(15):1856-1862, link to document DOI: 10.1016/j.jastp.2008.01.015


(2) The experimental GNSS TEC Calibration online (Reference: L. Ciraolo, F. Azpilicueta, C. Brunini, A. Meza, S. M. Radicella . "Calibration errors on experimental slant total electron content (TEC) determined with GPS". Journal of Geodesy 81.2 (2007): 111-120 link to document DOI: 10.1007/s00190-006-0093-1

These tools are publicly available within one simple, reliable and user-friendly resource. The services are free online for web users at
