资源简介:
The lysimeter array is a collection of 105 snowmelt lysimeters that
collect discharge measurements at the base of the snowpack. Each
lysimeter is a polyethylene pan with 22 cm high vertical walls and 47
cm by 39.5 cm in horizontal extent resulting in a footprint area of
~1,850 cm2. The height of the lysimeter walls prevent both the loss of
water out of the lysimeters and the influx of water from saturated
zones along the snow-soil interface [Kattelmann, 2000]. This location
collected data during spring snowmelt (April through July) for water
years 1998 through 2003. From 1998 through 2001, the array was
organized as a two meter grid nested within a four meter grid. The
1998 water year had only 36 lysimeters installed. In the 2002 water
year, 15 of lysimeters on the perimeter were relocated to increase the
density of the inner grid. Lysimeters were moved from locations of low
snow accumulation on the eastern edge and a region that collects
debris during melt on the western edge. Meltwater collected by the
lysimeters flowed to an underground laboratory through flexible PVC
piping into Rainwise Rainew Tipping Bucket Rain Gauges. The cumulative
number of tips were recorded by a Campbell Scientific CR1O data logger
at one hour intervals summed to daily totals for this dataset. The
precision of outflow is approximately 11 ml (~0.06 mm given the
footprint of the lysimeter). This dataset includes the coordinates for
each lysimeter of the Soddie lysimeter array. Coordinates are in UTM
projection, zone 13N, datum NAD83.
