At the start of the 1993-1994 field season, the Howard Glacier meteorological station was constructed at the same coordinates as stake 31 on the glacier's mass balance grid (latitude of 77-40-17.36222 S, longitude of 163-04-44.83507 E, and elevation of 472.49343 meters above sea level).  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 20 minutes between November 20, 1993 and November 27, 1995, and every 15 minutes thereafter.  This has resulted in approximately 20 values being recorded for final storage in every output interval.
