Abstract:
A combination of snow depth, snow temperature, snow water equivalent (SWE), and albedo measurements were taken from the spring of 2000 to the fall of 2002 at five sites near Council, Alaska. The sites vary in land cover type from forest to tundra. The purpose of the investigation was to understand the potential effects of climate change on the region by measuring how conditions change along a vegetation gradient. These data, which characterize snow cover and snow-holding capacity of various vegetation types, can help scientists understand how key meteorological events impact the arctic landscape. Data files, available via FTP, are in Excel format and include plots of the data and supplementary data information.

Attribute_Accuracy_Report:
Snow Depth The brush at the Bear Creek site was so dense that the researchers found it difficult to collect the 100 m line data. Thus, they did not collect data as often here. Furthermore, the Bear Creek site was flooded in 2002, forming an aufeis (new ice formed on top of old ice), which prevented snow depths from being recorded. The 'long line' data--position (UTM meters) and snow depth (cm)--have not been adjusted for the natural tendency of the operator to 'wander' about a straight line. The plots were adjusted so that the raw data fit the actual length of the straight line, by forcing each line to a fixed length. Please see the 'Plots' tab in the LongLines Excel files and refer to the 'Notes' tab for further explanation. Snow Temperature The summer temperatures collected with the Campbell CR-10X data logger and thermistors have questionable accuracy due to lack of solar shielding. Because of a large number of equipment failures, large gaps exist in some of the snow temperature data records. Albedo In several cases, the albedo meter was shaded, and/or the recorded value was greater than one. The actual albedo of the snow cover and vegetation is not known in such instances. Snow Water Equivalent (SWE) Air temperatures that were above freezing were a common source of error. The wet snow stuck to the core barrel resulting in low values. These data were noted as 'bad samples'. Please refer to the 'Notes' page of the data file for information on questionable data measurements.
