The data in this product support analyses in the paper titled "The ecosystem wilting point defines drought response and recovery of a Quercus-Carya forest". The data in this submission include leaf area index (LAI_MOFLUX_2008_2009_2012.csv) and soil water retention curves (MOFLUX_SWRC_data.csv). Leaf area index Each data record in LAI_MOFLUX_2008_2009_2012.csv consists of transect level mean single-sided leaf area index (LAI) values for 5 transects measured during the growing seasons of years 2008, 2009, and 2012. Records are uniquely identified by Year and DOY (day of year). Data were collected using a plant canopy analyzer (model LAI-2000). Data columns are defined by headers. Missing data are represented by values of -9999. Table 1. Header definitions of LAI_MOFLUX_2008_2009_2012.csv data file. Column Header name Definition 1 Year Year of observation 2 DOY Day of year of observation 3 LAI_SE Mean LAI of southeast transect 4 LAI_S Mean LAI of south transect 5 LAI_SW Mean LAI of southwest transect 6 LAI_W Mean LAI of west transect 7 LAI_NW Mean LAI of northwest transect Soil water retention curves Soil water retention curves for two soil depth ranges (0-30 cm and >30 cm) are reported in MOFLUX_SWRC_data.csv. Soil samples were collected near the MOFLUX tower. Samples were evaluated periodically for soil water potential using a dewpoint potentiometer (Decagon Devices, Model WP4C) and a pressure plate as they dried over time. There are 4 columns of data in MOFLUX_SWRC_data.csv. The first two columns contain data for the 0-30 cm depth range, and the second columns contain data for the >30 cm depth range. Each curve is defined by volumetric water content (VWC, %) and soil water potential (SWP, MPa). Missing data are represented by values of -9999.
