Raw neutron counts from a soil water content hydroprobe at 15 NPP study sites at the Jornada Basin LTER, 1989-2019

This data package contains raw neutron count data for monthly soil
water probe measurements made at 15 net primary production (NPP)
study locations on Jornada Experimental Range (JER) and Chihuahuan
Desert Rangeland Research Center (CDRRC) lands. Once a month, soil
water content measurements are made at 10 depths (where possible) at
each of 10 access tubes at each of the 15 NPP sites using a neutron
probe (CPN Model 503DR Hydroprobe). This dataset consists of the
count of thermalized neutrons at 30 cm depth intervals to a maximum
depth of 300 cm. These counts are subsequently converted to
volumetric water content as provided in a separate EDI package
(knb-lter-jrn.210013003). The NPP sites these measurements are made
at represent the 5 dominant vegetation types of the Jornada Basin,
which consist of 3 shrub (creosotebush, mesquite dune, and tarbush)
and 2 grass (upland grassland and playa) types. Three NPP sites are
located in each of the types. Collection of this dataset was
discontinued when the neutron probe instrument was replaced in
mid-2019. Neutron probe soil water content data are still collected
from the same NPP locations using a new instrument, and the raw
neutron counts and corrected VWC data are found in EDI dataset
knb-lter-jrn.210013003. This dataset is complete.
