The data

The world has produced extraordinary climate data over the last decade. Satellite verification of emissions. Real-time air quality from tens of thousands of stations. National inventories running back to 1750. The problem isn't a lack of data. It's that the data lives in dozens of fragmented systems, in different formats, with different schemas, different access rules, and different release cadences.

Jana surfaces, harmonizes, and serves the leading open climate datasets through one API. We don't replace the providers. We make their work usable in hours instead of months.

Climate TRACE: Satellite-verified emissions Asset-level greenhouse gas emissions for individual facilities, sectors, and countries worldwide. Measured by satellite remote sensing combined with AI/ML models, independent of company self-reporting. 53.4 million emission records across 1.3 million emitting assets in 251 countries, covering 26 sectors. Monthly updates. Provided by Climate TRACE.

OpenAQ: Ground-level air quality Real-time and historical air quality measurements from monitoring stations worldwide. What people actually breathe, measured at the ground level. 1.49 billion measurements from 50,514 stations across 159 countries, covering 24+ parameters including PM2.5, PM10, NO2, O3, SO2, CO, and black carbon. Updates in real time. Provided by OpenAQ.

EDGAR: Global emissions modeling Scientifically modeled emissions inventories at national and gridded level. The longest consistent time series available, 1970 to 2024, applied with the same methodology across 225 countries. 612 million+ records including gridded data at 0.1-degree resolution (about 11km). The gold standard for cross-country comparison. Provided by the Joint Research Centre, European Commission.

Global Carbon Project: Historical carbon budgets National CO2 emissions by country going back to 1750, plus global carbon and methane budgets. The dataset cited in every IPCC report. 221 countries, 1750 to 2024 for national totals. Annual updates timed to COP. Provided by the Global Carbon Project international research collaboration.

GLEIF: Corporate ownership linking (early-stage) The global registry of Legal Entity Identifiers with parent and subsidiary ownership relationships. 3.26 million legal entities across 236 jurisdictions. Today we have matched roughly 6,200 entities (about 2% of the GLEIF database) to Climate TRACE assets. The goal is to let an investor trace from a portfolio holding to real-world emissions. Active development.

NOAA Storm Events: US extreme weather (early-stage) Detailed records of significant weather events across the United States. 639,467 events across 54 types from 2015 to 2024. Loaded and queryable today, US only. Global extreme weather coverage is a longer-term goal.

The data is open. The work is the unification.

• One schema. Every dataset is reshaped into consistent, queryable structures so a single query can cross sources.
• One auth. One token, one set of rate limits, one place to manage access.
• Geospatial joins. Air quality stations link to nearby emitting facilities and EDGAR grid cells in a single query.
• GIS and notebook ready. Compatible with QGIS, ArcGIS, Google Earth Engine, and Jupyter via the Python SDK.
• AI-native. A Model Context Protocol server connects Claude, Cursor, and ChatGPT to live Jana data, not training data.

We are constantly evaluating new datasets. None of the items below are committed. They are shortlisted based on user demand, regulatory relevance, and technical fit.

Land, forests, and fire: Global Forest Watch (EUDR compliance, TNFD reporting), NASA FIRMS (active fire detection from MODIS/VIIRS satellites). Energy and infrastructure: Global Energy Monitor (power plants, pipelines, terminals, operational status worldwide). Climate and physical risk: ERA5 from ECMWF (climate reanalysis, hourly resolution back to 1940). Nepal and South Asia: Nepal Department of Environment air quality stations, DHM hydrology and meteorology, ICIMOD regional products, Open Data Nepal. Socioeconomic and corporate: World Bank Open Data, OpenCorporates. Reference geography: Natural Earth, geoBoundaries.

The data on Jana is not ours. The providers are independent scientific bodies, open-data foundations, and international research collaborations. We don't filter what they say. We don't second-guess their methodology. We make their work accessible. The result is climate evidence you can cite, defend, and act on, regardless of which side of any given argument you're on.
