Precipitation at 1 minute intervals for rain gauges 2-5 with R1 excluded due to periods of interruption. Spatially averaged rainfall over the watershed is calculated in this dataset based on relative coverage of each rain gauge determined from a Theissen polygon map.
This files presents all of the flux data post-EdiRe processing at 30 minute resolution. Included in this file is: Ux = Mean wind speed in the x-direction, Uy = mean wind speed in the y-direction, Uz = mean wind speed in the z-direction, Co2 = CO2 atmospheric concentrations, H2O = Water atmospheric concentrations, Press = barometric pressure, Air Temp = atmospheric temperature, wind speed = mea
n wind speed towards 216 degrees from north, H Flux = sensible heat flux, LE Flux = latent heat flux, C Flux = carbon flux.
Distance of crust surface to a crossbar set into the soil. Three "torvane" measurements that measure the torque needed to break the crust is also recorded. These measurements are made monthly near each of three monitoring towers (East, Middle, West) on the Scrape Site.

A 2-year experiment with ambient, reduced, and enhanced precipitation as well as nitrogen additions was designed to compare the performance of the encroaching C3 shrub (honey mesquite Prosopis glandulosa) to the dominant C4 grass (black grama Bouteloua eriopoda) in terms of photosynthetic rates and leaf water status. Precipitation manipulations dramatically enhanced natural variability and generated a range of rainfall scenarios that could have only been studied only after a multi-decade effort using natural conditions.We use vegetation cover as a proxy for plant biomass to avoid confounding spatial and temporal variability or confounding the impact of harvesting. Individual cover of plant species was measured using three parallel transects per plot. This study is complete.

Stocking rates for cattle, horses, and sheep are provided for the Jornada Experimental Range beginning in 1916. Goats were few and are included as part of the sheep category and not differentiated.
