st: constant variable as IV in panel?

Hi everyone,
I want to estimate a panel model with observations on approx. 90
countries for five points in time between 1980 and 2005. However, one of
my explanatory variables is endogeneous. The only possible instrument is
a variable on climatic zones. So it would be the same for each country
over all points in time. How can I put this into my model? Do I just put
the same value for each country over all the points in time and then use
xtivreg?
Best
Matthias
