Climate data ยท Geoscience evidence ยท AI tools

Research records, shipped tools, and field-informed systems.

Hao's Notes is the public surface for my climate data work, geoscience evidence, shipped tools, and local-first systems. It keeps the original al-folio homepage structure, while giving the active work a wider and more organized presentation.

Current work

Active tracks, organized as working lanes.

Updates are organized as maintained work lanes: public data systems, product builds, research engines, and training tools.

OP-01 LIVE SYSTEM

CCUS Policy Hub

Public policy and project intelligence layer for CCUS deployment, regulation, and dMRV evidence. Current work focuses on keeping the data and policy pages coherent as the database changes.

Open system โ†’
OP-02 PRODUCT BUILD

Ownly

Local-first ownership memory across Obsidian, web, PWA, and agent-readable CLI surfaces. The active track is reliability, terminology, onboarding, and cross-surface consistency.

Open app โ†’
OP-03 RESEARCH ENGINE

AlphaEngine

Experimental research platform for data foundations, factor panels, model training, and reproducible strategy records across selected US and China pools.
