To put the animation of GHCN-v2 stations with data in perspective, I decided to put together charts of data availability for every country in the GHCN-v2 data set for the period January 1850 to April 2010.
See also E.M. Smith's NOAA/NCDC: GHCN – The Global Analysis and a related thread on ClimateAudit.
You can find all of the charts here.
Here are the graphs for a few cases:
