Ashley Dene Dry FLUXNET Release 2025_r1

<br>This release consists of flux tower measurements of the exchange of energy and mass between the surface and the atmospheric boundary-layer using eddy covariance techniques. Data were processed using PyFluxPro (v3.4.21) as described by Isaac et al. (2017) for the quality control and post-processing steps. The final, gap-filled product containing Net Ecosystem Exchange (NEE) partitioned into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER) has been produced using the ONEFlux software as described in Pastorello et al (2020). This data set has been produced as part of the FLUXNET Shuttle project.</br> <br>Ashley Dene Dry is a paired site, growing irrigated and non-irrigated lucerne & #40;Medicago sativa L.& #41; until 2020, then converted to dairy pasture with rotational grazing. It is located on a research dairy station on the Mid-Canterbury plains, South Island, New Zealand, owned and managed by Lincoln University. The lucerne crops and the pivot-irrigation system were established in spring 2015. The flux sites began operating in 2015/16. The research is supported by the Endeavour Fund and the Strategic Science Investment Fund from New Zealand’s Ministry of Business, Innovation and Employment, and for the pasture phase also from the New Zealand Agricultural Greenhouse Gas Research Centre.</br>
