Mid-Atlantic methane dashboard

This dashboard is set up to visualize the monthly Mid-Atlantic emissions products in:

../imi_output/Marcellus_operational_TROPOMI_12km_KF/kf_inversions/for_jpl/emissions

It now works as a regional grid explorer instead of a state-by-state CONUS dashboard:

  • The map shows gridded methane emissions for a selected dataset, month, and sector.
  • The bar chart summarizes regional totals for the selected month.
  • The line chart shows the monthly regional total over time for the selected sector.
  • Dataset options are discovered automatically from subdirectories under emissions/, with kalman_prior currently excluded from the dashboard. Display labels are mapped so prior shows as “GHGI”, posterior as “TROPOMI estimate”, and blended_posterior/posterior_blended as “Blended TROPOMI+GOSAT estimate”.

Build data assets

The dashboard expects data/manifest.json, GeoTIFFs, and copied NetCDF files generated by:

python scripts/build_tiles.py

The script reads monthly period labels from the local periods.csv files used by the inversion setup, and defaults the UI to the posterior dataset when available.

Serve locally

From the example-dashboard/ directory, serve the files with a static web server, for example:

python -m http.server 8000

Then open http://localhost:8000.
