The station was set up to sample sensors every 30 seconds and send summary statistics (for example, averages and maximums) to solid-state storage modules every hour between December 30, 1994 and November 24, 1995, and every 15 minutes thereafter. This has resulted in approximately 20 values being recorded for final storage in every output interval.
