Plans for the 2021 NDACC Steering Committee annual meeting are underway. Originally scheduled to take place at the NOAA Center for Weather and Climate Prediction (NCWCP) in College Park, MD, the meeting has been changed to a virtual format because of ongoing COVID-19 restrictions. The meeting will take place the week of 13-17 September 2021. As with the 2020 meeting, Martine De Mazière and BIRA-IASB have
NDACC News and Events - 2021
As presented at recent Steering Committee Meetings the NDACC DHF has been transitioning from service at NOAA/CPC to NASA Langley Research Center (LaRC). In the Fall 2020 meeting we noted that the DHF at LaRC was running in mirror mode, with all files running through the format/ingest codes. Routine checking of database listings has confirmed that all files accepted at LaRC and at NOAA/CPC have been in sync.
A Cooperating Network Agreement between NDACC and the European Brewer Network (EUBREWNET) was finalized on 19 April 2021.
As a result of this agreement, John Rimmer (University of Manchester) and Alberto Redondas (State Meteorological Agency of Spain (AEMET) and the NDACC Brewer Working Group Representative) have been named EUBREWNET Co-Representatives to the NDACC Steering Committee.
The NDACC Lidar Working Group (LWG) has relocated and redesigned its website. The new website URL is https://lidar.jpl.nasa.gov/ndacc/index_ndacc.php. The website features a review of the NDACC lidar stations and instruments, with new links and functionality to check data availability and access them. Fine-tuning of the website content will continue over the upcoming weeks.
Updates and corrections to the GMI chemical mechanism and its input files have been used to create a new Hindcast simulation with MERRA2 meteorology. The changes compared to the previous GMI simulation are generally small and you probably won’t see any large impacts on chemical constituents. The greatest impacts are on temporal and spatial evolution of polar ozone depletion and on NOy partitioning globally due a change in stratospheric sulfate surface area. Mechanism and input changes are listed below.
