In January 2021, the solar FTIR instrument at NCAR in Boulder was accepted as a formal NDACC station. The Infrared Working Group (IRWG) is composed of 20 stations making daily observations and producing vertical profiles of 12 standard species. The Boulder station has been operating since 2010 at NCAR by PI James Hannigan. In 2017, the instrument was upgraded to a Bruker 125 that is the standard across the NDACC.
On October 18-20,2021, the NASA/GSFC Greenbelt ozone group of Ryan Stauffer (NDACC Sonde WG Co-Chair), Debra Kollonige, and Anne Thompson (former NDACC SC Co-Chair) traveled to the NASA/WFF NDACC station to meet with Rhonie Wolff and Tom Northam and perform two dual ozonesonde test launches. The test launches were part of the ongoing ozonesonde data quality assurance effort, and compared different ozonesonde (EnSci and Science Pump Corp.; SPC) and radiosonde manufacturers, and ground receiving stations.
Mea culpa, mea culpa! This summer we discovered there was another bug hiding in our 2020 simulation. If you happened to look at tropospheric ozone from May-Dec you might have wondered how the world got so polluted…especially with reduced travel during the pandemic. This affected all 2020 files. Please replace any 2020 file you currently have with a new one!!!
The new Dobson, Sonde, and Lidar files have ‘MR2V4’ in their name, while the current FTIR files are ‘MR2V3’. All files can be downloaded via anonymous ftp from
Dobson Observations from Utqiaġvik, Alaska have been operated by the National Oceanic and Atmospheric Administration, Global Monitoring Laboratory since 1973 (Figure 1).
It is our pleasure to send you the First Announcement of the 30th International Laser Radar Conference (ILRC-30), to be held from June 26 to July 1st, 2022 in Big Sky, Montana, USA. The announcement flyer is here. Note that ILRC-30 will be co-located and held in parallel with the Coherent Laser Radar Conference (CLRC).
