One on the Warm Arctic–Cold Eurasia pattern (Cai et al., 2023), and the other about estimating PM2.5 and ozone concentrations using machine learning algorithms (Yan et al., 2023).

A first paper describing the TRACE Regional Atmosphere–Carbon Ensemble system, developed by Hans Chen, has been published in JAMES: Chen et al. (2023).

Happy New Year!

Starting in 2023, Hans Chen will be working as an Assistant Professor at Chalmers University of Technology in Sweden.

At Chalmers, he will further develop new techniques to estimate greenhouse gas emissions and removals using atmospheric observations, as well as continue his research on climate variability and change with a focus on the polar regions.

Hans Chen was recently interviewed by Radio Sweden (Sveriges Radio) about monitoring emissions using new satellites. You can listen to the full interview in Swedish here:

Nya satelliter avslöjar dolda utsläpp av växthusgaser.

Hans Chen has been interviewed by the Extrakt online magazine about his research on estimating carbon dioxide emissions using satellites. You can find the full article online in Swedish: Bilder från rymden avslöjar koldioxidutsläpp.

We recently published an extensive review paper on permafrost characteristics and changes in the Arctic and the Third Pole: Wang et al. (2022).

Our study assessing potential measurements of atmospheric CO₂ and NO₂ from the upcoming CO2M satellite mission for estimating fossil fuel emissions has been published: Kaminski et al. (2022).

Our work on reconstructing Arctic amplification variations over the past millennium using paleoclimate data assimilation has been published: Fang et al. (2022).

Here is a press release in Swedish: Forskare har kartlagt tusenåriga temperaturförstärkningar i Arktis.

We recently published a paper about increasing carbon release from terrestrial ecosystems in autumn: Tang et al. (2022).

Here is the press release in Swedish: Trots kallare höstar ökar nettoutsläppen av koldioxid på norra halvklotet.

Hans Chen has received a starting grant from Formas for a four-year research project on “Improved monitoring of carbon dioxide emissions in Scandinavia using satellite and ground-based observations”.
