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: | Orthomosaic images and digital elevation models (DEMs) were created to derive snow cover area and subsequently snow depletion curves (orthomosaic images) as well as to understand the site-specific topography and the local hydrology at the respective sites (DEMs). |
| Data Usage: | Orthomosaic images (.tif) and DEMs (.tif) can be viewed in GIS software/ based on WGS84. All data products uploaded have been cut to size to cover mainly the area of the 200x20 m swath. |
