NDACC and ACTRIS signed a Memorandum of Understanding (MOU) on June 6, 2024 to collaborate and mutually exchange relevant expertise, to share data and research, and to promote both NDACC and ACTRIS communities to continue working closely together.

Following two years of equipment procurement and a visit earlier this month from Fernando Chouza (JPL) to help with receiver integration, Lauder finally have a redeveloped ozone lidar that is ready to return to routine operations. The original ozone lidar was installed at Lauder, New Zealand, in the early 1990s...

In November 2023, the solar FTIR instrument at Anhui Institute of Optics and Fine Mechanics (AIOFM) in Hefei, China was accepted as a formal NDACC station. The Infrared Working Group (IRWG) is composed of 22 active stations making daily observations and producing vertical profiles of 12 standard species.

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.
