Köppen climate classification

The Köppen climate classification, also known as the Köppen–Geiger classification, is one of the most widely used climate classifications. This project page contains information about the Köppen classification and output from Chen and Chen (2013).

Barents Oscillation

The Barents Oscillation (BO) is an atmospheric teleconnection pattern that influences weather and climate in the Arctic and parts of Eurasia. This page describes the spatial BO pattern identified by Chen et al. (2013) and provides data for the BO index.

Below is a list of other research projects that we are or have been involved with. Note that the links lead to external pages.


Attributing and Verifying European and National Greenhouse Gas and Aerosol Emissions and Reconciliation with Statistical Bottom-up Estimates (AVENGERS) is a Horizon Europe project that aims to develop methodologies to reconcile reported greenhouse gas emissions with top-down estimates based on atmospheric observations.

Copernicus CO2 (CoCO2) was an EU Horizon 2020 project whose main objective was to build a prototype system for an operational anthropogenic CO2 emissions monitoring and verification support capacity.

CO2 Human Emissions (CHE) was a predecessor to Copernicus CO2, funded by EU Horizon 2020 to carry out preparatory work for the CO2 emissions monitoring prototype.

CCFFDAS was an ESA project that investigated the potential of monitoring CO2 emissions using satellites using the comprehensive Carbon Cycle and Fossil Fuel Data Assimilation System.

Atmospheric Carbon and Transport – America (ACT-America) was a NASA-funded project that studied the regional atmospheric transport and surface fluxes of carbon over eastern United States through airborne field campaigns.
