`plumax` — Roadmap & Architecture

plumax — Roadmap & Architecture¶

Mathematical models for plume simulation, methane retrieval, source identification, and emission estimation.

The detailed roadmap now lives in roadmap/, one file per tier. This page is a one-screen pointer. Start with the roadmap index for the philosophy, the tier table, and the architectural principles.

Quick links¶

• Roadmap index — philosophy, tier table, principles
• Prerequisites — Met field infrastructure
• Tier I — Gaussian family
• Tier II — Lagrangian particle transport
• Tier III — Eulerian finite-volume transport
• Radiative transfer (RTM) stack — parallel track
• Tier IV — End-to-end coupled system
• Tier V — Source population & forecasting
  • V.A — Instantaneous emission estimation
  • V.B — Point process model (TMTPP)
  • V.C — Persistency
  • V.D — Total emission estimation
• Operational attribution — unified-stack success-story plan — projected end-to-end pipeline (3 instruments, 3 orchestration phases) showing how MARS-style attribution rebuilds on georeader + GeoCatalog + geotoolz + plumax. (Now lives in the research journal under notes/geotoolz/ alongside the rest of the geotoolz design notes.)

The cycle, in one diagram¶

Every tier in plumax follows the same six-step loop:

Simple model → model-based inference → emulator
            → emulator-based inference → amortized predictor → improve

The cycle structure is the architecture. Each tier swaps in a richer forward model, but the inference loop, the validation tests, and the upgrade discipline are the same. See the roadmap index for the full diagram and the rationale for each step.
