Non-USGS entities have maintained mass balance measurement programs at different times, with varied lengths and observational records. USGS uses this data for regional scientific work, where appropriate, and as such provides the associated data to the public here. This data is derived from multiple sources, and may be of varying format and provenance. The details of each specific dataset should be studied carefully, and are well documented within each release.
