Daily rawinsonde data for San Cristobal Island (Galapagos) were
keyed from the original hardcopy forms as part of NCDC's Climate
Modernization Database Program and then sent to DSS for
post-processing and quality control. The overall period of record is
December 1990 to December 1998, but there are missing months.
Generally, soundings are available once-daily, but there are
occasionally two per day, and there are days with no soundings at
all. The data are presented in two sets: a conventional stack of
mandatory and significant levels, and a stack of level data at
high-resolution (levels every 10 seconds up to 5 minutes, then every
30 seconds up to 15 minutes, then every minute).
