Teal: Explore climate data easily    


Teal is a free visualisation tool that enables you to explore climate variables for the past 70+ years, from 1950 to near real time, and carbon emissions from 1960.

A global map shows climate data by country and sub-country. These show as temporal resolutions.

Teal is not an acronym, rather the name comes from its colour!



Teal provides free access to easy-to-use climate data. You don’t need technical expertise in complex datasets to use Teal. . The hard work has already been done for you by WEMC climate data specialists. In a few clicks you can visualise and download the data, as well as graphs, that can be used to inform  your decisions.


Plan long and short term scenarios

Make management decisions

Raise awareness about climate change

Invest in infrastructure assets


TEAL was built on previous C3S demo tools: the European Climatic Energy Mixes (ECEM, 2015-2018) demo http://ecem.wemcouncil.org and the C3S Climate & Energy Educational Demo (2019-2020): https://edudemo.climate.copernicus.eu/

The carbon emission data comes from the Global Carbon Project (GCP, https://www.globalcarbonproject.org). The best and only reference to the data is https://doi.org/10.5194/essd-11-1783-2019 which is updated every year. Additional information can be found at the GCP budget page: https://www.globalcarbonproject.org/carbonbudget

Teal is a free visual tool that enables you to explore climate variables, carbon emissions and other indicators and features which are being actively developed and added. Documentation, guidance, functionality and data are periodically generated and reviewed for inclusion. The developers are not liable for consequences due to decisions taken on the basis of the data displayed in and provided through the tool.

Climate Variables

The following climate variables can be selected via the Edu Demo: air temperature, wind speed (at 10m height), total precipitation and solar radiation. These are chosen both for their importance as climatic indicators, but also because the are the main factors affecting the energy variables displayed with the Edu Demo.

Air temperature is the main indicator of how the climate evolves. It is linked to electricity demand, and can also affect solar power production.

Wind speed provides an indication of the strength of the atmospheric circulation. It is also linked to wind power production.

Precipitation provides an indication of how wet or dry the earth system is. It is also linked to hydroelectric production (the latter is not currently available on the Edu Demo).

Solar radiation is the amount of energy coming from the sun that reaches the ground. It is also linked to solar power production.

Carbon dioxide (CO2) is a colourless, odourless and non-poisonous gas formed by combustion of carbon and in the respiration of living organisms and is considered a greenhouse gas. Emissions means the release of greenhouse gases and/or their precursors into the atmosphere over a specified area and period of time.

Frequently Asked Questions:

Why is there only historical data?

Currently, Teal uses ERA5 historical reanalysis data from the Copernicus Climate Data Store.

In the future there will be climate projections and seasonal forecasts (for Europe) added.

Why does the data end at 2020?

At launch, Teal supports historical data until end 2020. However in future updates we will bring the available historical data close to ‘real-time’ (1 week lag).

Including the planned climate projections updates, this will expand the total covered time range to 1979 – 2100.
