The global COVID-19 pandemic and its associated restrictions on human activity presented a unique opportunity to study changes in atmospheric composition. The analysis of the impact of stay-at-home measures on air quality has primarily relied on surface in-situ measurements and satellite platforms.

This year’s NDACC Steering Committee meeting took place from September 11th to 14th at the Kultur- and Tagungszentrum in Murnau, Germany. Murnau is a small town close to the Bavarian Alps, about 60 km south of Munich. Deutscher Wetterdienst Hohenpeissenberg hosted the meeting choosing the picturesque location with meeting venue, hotels, and restaurants in easy walking distance.

An International Symposium Celebrating 35 Years of Global Atmospheric Research Enhanced by NDACC/NDSC Observations

The Sonde Working Group is pleased to announce the activation of their new webpage.

Bahramvash-Shams performed a detailed analysis of recent Sudden Stratospheric Warmings (SSW) using the Modern-Era Retrospective Analysis for Research and Applications, Version 2 (MERRA-2) dataset. This study took advantage of the continuous observations provided by the NDACC at five Arctic Infrared working group (IRWG) and ozonesonde stations, where vertical profiles of ozone are routinely measured consistently over the long term.

The Ozone Mapping and Profiler Suite (OMPS) Nadir Mapper (NM) instruments onboard the Suomi NPP and NOAA-20 satellites have been used to produce a HCHO record from 2012 to the present. Formaldehyde products from the OMPS-NM instruments were recently updated, compared with TROPOMI observations over 12 geographical regions, and validated with NDACC FTIR HCHO observations at 24 ground stations.

The Quadrennial Ozone Symposium Organizing Committee announces QOS 2024: Boulder, Colorado, USA from 15-19 July 2024. The meeting includes both in-person and hybrid virtual options.

On 25 April 2023, ACTRIS was established as a European Research Infrastructure Consortium (ERIC) for state-of-the-art data and services in atmospheric research. The establishment of ACTRIS ERIC brings to fruition a long-term effort by several European countries to create a sustainable infrastructure supporting atmospheric and climate research. With ACTRIS, researchers, industry, and countries get access to key information on the state of the atmosphere and to the best research platforms in Europe for understanding and predicting the evolution of atmospheric composition and its impact on air quality and climate.

The second phase of the Tropospheric Ozone Assessment Report (TOAR-II) is organized in focus working groups that should produce the papers for the TOAR-II Community Special Issue (the first step of the second Tropospheric Ozone Assessment Report).

For 2023 and beyond, model support for the FTIR, Lidar, Dobson, and Sonde working groups will be provided from a GEOS called Replay. Replay meteorology is very close to MERRA2, particularly below 10 hPa. It is run with the same chemistry mechanism as the GMI CTM.
