[IGSMAIL-7672] IGS TWG Troposphere Comparison Site is open!

[Hackman, Christine CIV NAVOBSY, N3EO]

Dear Colleagues:  The IGS Troposphere WG Troposphere Comparison website is now open! It allows you to explore what kind of troposphere estimates are available at different locations around the world, and in some cases to compare them. Data types currently included: VLBI, GNSS, radiosondes, and numerical weather models.

 

Access it here: twg.igs.org/Tropo_Comp_Site/index.php

 

Or from the IGS TWG website (twg.igs.org/index.html): click "GOP-IGS Troposphere-Comparison Website" (towards top right of the page, on same line as the giant "Troposphere").

 

Some areas are not yet available, and many need improvement, but we hope you enjoy using the site.

 

Finally: we thank the many contributors listed below!

 

Sincerely,

Christine Hackman, Jan Dousa and Sharyl Byram
