Snow water equivalent data for Niwot Ridge and Green Lakes Valley, 1993 - ongoing.

Snow pits were excavated at various locations on Niwot Ridge and
within the Green Lakes Valley. Temperature and snow density were
measured at various depths throughout the snow cover profiles to
characterize the temperature and snow water equivalent (SWE) of the
snowpack throughout the year. Snow density was measured at 10-cm
intervals using a 1000-ml cutter. This dataset contains derived
values of SWE from snow profile measurements.

研究团队于尼沃特岭（Niwot Ridge）及绿湖谷（Green Lakes Valley）的多个点位开挖雪坑。
沿积雪剖面的不同深度测定温度与雪密度，以表征全年积雪的温度及雪水当量（Snow Water Equivalent, SWE）。
雪密度采用1000毫升雪样采样器，以10厘米为间隔完成测量。
本数据集包含由积雪剖面测量所得的雪水当量衍生值。
