Abstract:

This data package contains 30-minute standard meteorology and ancillary data collected at an eddy covariance tower in the Tromble Weir Watershed area of the Jornada Basin in southern New Mexico, USA. These data are used to quantify the water and energy balances in a small experimental watershed, including observational studies to calculate groundwater recharge as a water balance residual, to build relations between soil moisture state and ET flux, and to quantify land-atmosphere interactions and improve our understanding of the eddy covariance method. Additionally, they have been used in modeling studies as a validation of model performance. This file presents the ancillary data collected at the eddy covariance tower, excluding the 20Hz flux measurements that are archived at AmeriFlux (site US-Jo2; http://ameriflux.lbl.gov/sites/siteinfo/US-Jo2). This includes soil moisture and temperature at 4 depths, air temperature and pressure, humidity and vapor pressure, ground heat flux, incoming and outgoing longwave and shortwave radiation, photosynthetically active radiation for a subset of the study period, and surface soil temperature. Instrument descriptions and detailed procedures are found in the references listed in the Methods section of this package. This is an ongoing dataset that will be updated annually.

Description:

General study design

The Tromble Weir Watershed is a small experimental watershed located in the East Bajada geomorphic unit of the Jornada Basin in southern New Mexico, USA. We have instrumented this watershed, which consists of a mixed Chihuahuan Desert shrubland, and have on-going measurements and modeling studies of hydrological, meteorological and phenological processes. The instrument network consists of 20 soil moisture profiles around an eddy covariance tower and 15 soil moisture profiles arranged along hillslope transects. A network of rain gauges and channel runoff flumes is also deployed.

This data package contains standard meteorology data and ancillary variables collected at the Tromble Weir Watershed tower (same location as eddy flux measurements). This eddy covariance tower is listed as an AmeriFlux site (US-Jo2; https://ameriflux.lbl.gov) and flux data from the location is archived in AmeriFlux standard formats at the link below (see "AmeriFlux data location"). Some of the variables present in this data package may also be present in the AmeriFlux files.

AmeriFlux data location

DOI links to AmeriFlux holdings of eddy covariance data from this tower are found in another EDI package for this site (knb-lter-jrn.210338005). Data at AmeriFlux can also be found by visiting their page for this site:

Instruments and measurement methods

Measurements in this file were all taken from the Tromble eddy covariance tower and averaged over 30-minute intervals. Volumetric water content measurements were performed using CS-616 soil water content reflectometers from Campbell Scientific that were installed near the EC tower at 5, 15, 30, and 50 cm depths. The soil moisture measurements were verified with gravimetric samples. Air temperature and atmospheric humidity were measured at 3.4 m height using a HMP45C sensor from Campbell Scientific. Different variables representing humidity (Relative Humidity and vapor pressure deficit) are provided for convenience. Incoming and outgoing shortwave radiation were measured with Apogee Instruments silicon-cell pyranometers that were installed in 2015 and mounted at 7 m height. Ground heat flux was measured using two ground heat flux plates, HPF01-SC from Hukseflux, installed at 5 cm depth. One plate was installed under bare soil and the second was installed under a vegetated soil. Thermocouples installed at 2 and 4 cm were used to estimate the surface soil heat storage. Total incoming solar radiation was measured using a pyranometer mounted at 5 m height (CMP3-L, Campbell Scientific). Net shortwave and net longwave radiation were measured using a radiometer mounted at 5 m height (CNR2-L, Kipp & Zonen). Soil surface temperature was measured with a SI-111 infrared radiometer made by Apogee instruments. Data was recorded at 30-minute intervals using a Campbell Scientific CR5000 datalogger. Data quality was assured by graphical analysis. Periods of instrument malfunction, or periods when instruments were removed from the tower for calibration or regular maintenance are indicated as data gaps filled with missing values.

Abstract:

The Jornada Basin Long-Term Ecological Research (LTER) program is part of a national network of long-term ecological research sites funded by the US National Science Foundation (NSF). The Jornada LTER program has been continuously funded since 1982 to develop general principles governing changes between grassland and shrubland ecosystems based on long-term data collected in the Chihuahuan Desert. We translate our findings to dryland ecosystems around the world, and forecast the dynamics of future ecosystem states in response to changing climate and land use.
