Description
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.
