Snow-substrate interface temperature and air temperature for the SALVO 2022 Campaign

Overview:

The springtime, surface-albedo transition in the Alaskan Arctic and the forcings that determine the duration and nature of that transition are the focus of our Snow ALbedo eVOlution (SALVO I & II) campaign. The SALVO team are assessing the “whys” and “how longs” of the stages of the spring melt during which albedo values drop from 0.8 to 0.1, the largest and most significant change of the year. The near-shore location of the ARM NSA observatory makes this an ideal place to investigate these melt stages.

Abstract:

The springtime, surface-albedo transition in the Alaskan Arctic and the forcings that determine the duration and nature of that transition are the focus of our Snow ALbedo eVOlution (SALVO I & II) campaign. The SALVO team are assessing the “whys” and “how longs” of the stages of the spring melt during which albedo values drop from 0.8 to 0.1, the largest and most significant change of the year. The near-shore location of the ARM NSA observatory makes this an ideal place to investigate these melt stages.
Purpose:

In addition to spot snow temperatures from snow pits, we installed BTS (Bottom Temperature Snow: Hiller et al., 2014) sensors connected to data loggers (Onset Computers model U23) at the snow-substrate interface. At each site, we chose a landscape feature representative of the respective site (ARM: drainage channel, BEO: LCP/ trough, ICE: barchan dune, CHK: drift apron after small pressure ridge) specifically to monitor water movements within the snow and get insight into the arrival of water at the base of the snow. Air temperature measurements were collected for site-specific temperature monitoring (sensors 5B - see metadata file).
Data Usage:Data is stored in excel files as a function of time (GMT). Temperatures are recorded in degree C in ten minute intervals. The measurements are instantaneous.
