Our data

The receipts behind every report.

The main page keeps things plain on purpose. This page is for anyone who wants to check our work: every number TerraCube shows traces back to a named, public scientific dataset listed below. Nothing is bought from data brokers, and nothing is invented.

  • Weather forecast

    NOAA (GFS, HRRR) · ECMWF open data

    The week ahead is read from public numerical weather models run by NOAA and ECMWF, with a Hyperlocal / Regional / Global badge for how sharp the forecast is at your point.

  • Long-term climate

    NASA NEX-GDDP-CMIP6

    Future temperature, rainfall and seasonality come from NASA's downscaled CMIP6 projections — the same data climate scientists use — sampled at your address across low, medium and high emissions pathways.

  • Climate baseline & type

    CHELSA v2.1 · Köppen-Geiger

    Today's climate normals and the property's climate type are anchored to peer-reviewed global datasets at roughly 1 km resolution, not a coarse regional average.

  • Building energy

    RECS / CBECS (US) · TABULA (EU)

    Heating and cooling estimates use national building-stock data — US energy surveys and the EU's measured-calibrated TABULA typologies — combined with local climate.

  • Energy prices

    EIA (US) · Eurostat / IEA (world)

    Cost figures use published residential electricity prices by state or country, so the dollar amount reflects local rates rather than a single global guess.

  • Buildings & address

    Overture Maps · OpenStreetMap

    We locate the building footprint and geocode the address from open mapping data covering most addresses worldwide.

[ no data ]

The honest-gaps promise. When a point sits over ocean, falls outside a dataset, or has no measured coverage, TerraCube marks it “no data” and tells you why — rather than filling the gap with a guess. A number you can act on is a number you can trace.

Every report also states, on the page, which dataset, baseline and model produced each of its numbers — so the attribution travels with the answer. Want to see how those numbers are built? Read the full methodology or the FAQ.
