Abstract: 

This ongoing dataset contains annual aboveground net primary productivity (ANPP) data from a study at the Jornada Experimental Range (JER) in southern New Mexico. The study was designed to assess the effect of interannual variability in precipitation on average aboveground net primary productivity (ANPP) in Chihuahuan Desert grasslands.

The study began in 2009, has five precipitation treatments (see Methods) and contains 50 plots (10 per treatment). This data package contains 6-year (2009 to 2014) means of ANPP per plot. Annual and more recent data are available and will be released pending an upcoming publication.

Abstract: 

This completed dataset contains soil moisture data from a study at the Jornada Experimental Range (JER) in southern New Mexico. The study was designed to assess the effect of interannual variability in precipitation on average aboveground net primary productivity (ANPP) in Chihuahuan Desert grasslands. The study began in 2009 and has five precipitation treatments (see Methods).

While the study began in 2009, contains 50 plots (10 per treatment) and is ongoing, these data were only collected from July 2011 to December 2013 in a subset of 20 plots (4 per treatment). This dataset is intended to provide information about the amount of water in the top 30 cm of soil as well as verify that experimental precipitation manipulations are effective.

Abstract: 

Surface evaporation is measured weekly to twice weekly using an evaporation pan compatible with standard National Weather Service evaporation measurements. Measurements are made twice per week during hot periods because of high evaporation rate.

The following data is collected: number of days between measurements, beginning and ending measurement period, current, minimum, and maximum water temperature; initial water level; final water level; rainfall since last evaporation measurement, and calculated evaporation (inches).
