This archive includes a global set of Suominet reports updated in irregular intervals. Additionally, FSL network reports are now included in the set. The hourly reports, encoded in netCDF format, include surface pressure, surface temperature, relative humidity, and estimated column precipitable water vapor. Data spans the period from June 2001 to May 2007. Archived data includes real-time and post-processed reports.

Suominet is a network of ground-based GPS receivers and METPACKs which are used to estimate column precipitable water vapor, both in the zenith and along slanted ray paths to GPS satellites. Additional information, including a plot of suominet station locations can be found at the COSMIC Suominet site.
