Hillslope hydrologic monitoring data following the 2009 Station Fire, Los Angeles County, California, November 2015 to June 2017

This data release includes time-series data from two monitoring stations in drainage basins burned in the 2009 Station Fire, Los Angeles County, California. Both stations are located near the upper boundary of their respective watershed and were installed to study the effects of vegetation recovery on hillslope hydrology and debris-flow occurrence. The coordinates of the Arroyo Seco site are 34°14'13.10"N, 118°11'44.72"W. The coordinates for the Dunsmore Canyon hillslope site are 34°15'54.27"N, 118°14'14.41"W. The data include 1-minute time series of rainfall, soil water content, soil temperature, and soil matric potential recorded at two locations at both stations: AS1, AS2, DC1, DC2. The two locations at each site have the primary distinction of being in a non-vegetated location (AS1, DC1) or under vegetated canopy (AS2, DC2). The soil water content measurements were made at 3 depths below the ground surface in each pit (10, 25, and 50 cm). Soil temperature measurements were made in each pit (10 cm). Soil matric potential was measured with a tensiometer at AS1 (50 cm) and DC2 (50 cm), and includes an integrated soil temperature reading from the same instrument. All available data from the time period is included, but occasional lapses exist in the time-series due to various system issues and/or maintenance. The tensiometer data includes erroneous values where in-situ matric potential is outside of the range of the instrument and a data quality flag has been added to aid in the interpretation of these. Details of this study are described in the journal article: Smith, J.B., and J.W. Kean. 2018.
