It is the pistachio counterpart to [DASI](\u002Findices\u002Fdasi) for almonds, and uses the same construction principles — observable meteorological data, near-universal spatial coverage, and a base-100 relative scale.\n",{"question":50,"answer":51},"When will DPSI go live?","DPSI is currently in calibration with backtest data covering 2000 onwards. Live releases are scheduled to begin Q3 2026. To be notified when DPSI goes live, [sign up for our newsletter](\u002F#subscribe).\n",{"question":53,"answer":54},"How will DPSI compare to DASI?","DPSI uses the same framework as DASI but is parameterised for pistachio phenology. Pistachios are a long-cycle alternate-bearing tree crop with very different chilling and heat-unit requirements to almonds, so the variable weights and stage definitions differ materially.\n",{"question":56,"answer":57},"How can I access DPSI data?","Backtest series and methodology preview are available to Demeter subscribers via the [Demeter platform](https:\u002F\u002Fplatform.demeterdata.ag\u002F?utm_source=marketing-site&utm_medium=index_page_faq&utm_campaign=subscriber-platform).
