European Comparison of Absolute Gravimeters ECAG-2011

Published on Tuesday December 07, 2010

Some of you have been asking me if there will be a comparison of absolute gravimeters in Walferdange in 2011. The answer is definitively “YES”.

As usual, I propose that all the gravimeters will measure at 3 different sites starting the Tuesday 8th of November 2011 at 8 pm and finishing the Friday 11th of November 2011 in the morning.

If you are not able to come at the propsosed dates, you are more than welcome to come at any time before or after the comparison. Your results will sill be included in the final report.
The superconducting gravimeter will provide a precise estimate of the geophysical gravity changes.

There are 16 sites in the underground laboratory. If there are more than 16 participants, I will have to organise the comparison on the basis of “first come, first serve”.

Once more, I have decide call this comparison “European” to avoid confusion with the official ICAG. For those who are interested, we will propose the comparison to be registrered as a EURAMET key comparison.

Anyway, I encourage teams from non-European countries to participate to ensure a link between other regional comparisons organized in other parts of the world.

I hope to see you or your team in November 2011!!
