Purpose of collection

Glacier volume is strongly influenced by climate factors, such as temperature and precipitation. Changes in glacier ice volumes give some indication of changing climate conditions in New Zealand.
This dataset relates to the "Change in glacier ice volume" measure on the Environmental Indicators, Te taiao Aotearoa website.

Method of collection/Data provider

This data was collected by NIWA. NIWA uses measurements of the annual end-of-summer snowline for 49 glaciers to estimate glacier ice volumes. This is based on photographs taken during aerial surveys. Adverse weather means not all glaciers can be measured each year. It can also be difficult to identify the end-of-summer snowline, for example, when a recent snowfall obscures the snowline, or cloud cover or backlighting makes it difficult to see.
