TL;DR: In this paper , the authors used ozone lidars from NASA's Goddard Space Flight Center to better evaluate the characterization of ozone throughout the TROPOspheric Monitoring Instrument (TROPOMI) validation campaign.
Abstract: Abstract. A TROPOspheric Monitoring Instrument (TROPOMI) validation campaign
was held in the Netherlands based at the CESAR (Cabauw Experimental Site for
Atmospheric Research) observatory during September 2019. The TROpomi
vaLIdation eXperiment (TROLIX-19) consisted of active and passive remote
sensing platforms in conjunction with several balloon-borne and surface
chemical (e.g., ozone and nitrogen dioxide) measurements. The goal of this
joint NASA-KNMI geophysical validation campaign was to make intensive
observations in the TROPOMI domain in order to be able to establish the
quality of the L2 satellite data products under realistic conditions, such
as non-idealized conditions with varying cloud cover and a range of
atmospheric conditions at a rural site. The research presented here focuses
on using ozone lidars from NASA's Goddard Space Flight Center to better
evaluate the characterization of ozone throughout TROLIX-19. Results of
comparisons to the lidar systems with balloon, space-borne and ground-based
passive measurements are shown. In addition, results are compared to a
global coupled chemistry meteorology model to illustrate the vertical
variability and columnar amounts of both tropospheric and stratospheric
ozone during the campaign period.

TL;DR: The Ruisdael Consortium as mentioned in this paper is an agenda setting body in the atmospheric sciences, and contributes to the long term strategy of science in the Netherlands, and with its combination of academia, applied institutes and agencies it embodies a direct link between education, research, application and public outreach.
Abstract: <p>As of&#160; 2018 the atmospheric research community in the Netherlands, including universities, agencies and institutes, joined forces in the Ruisdael Consortium, named after the 17th century painter who depicted the skies over Holland with a realistic interplay of light, clouds, and the land surface. The consortium centres its activities around the combined use of experimental facilities and model development, aiming at better forecasts of the weather and air quality, as well as getting deeper insights into climate processes. While the driving force behind the consortium results from the urge to advance science, the societal spin-off is hard to neglect. The observational data as well as the high resolution models increasingly find their use in industrial applications such as the generation of sustainable energy, or the evaluation of air quality in urban areas. The Ruisdael Consortium acts as an agenda setting body in the atmospheric sciences, and contributes to the long term strategy of science in the Netherlands, and with its combination of academia, applied institutes and agencies it embodies a direct link between education, research, application and public outreach.</p><p>Selected examples of the Ruisdael activities are</p><ul><li>Coordinated actions in Amsterdam to study the urban climate for improving climate adaptation strategies in cities,</li> <li>Studies in Rotterdam of the interplay between climate change and potentially enhanced virus outbreaks,</li> <li>Fine weather forecasts for the wind and solar energy production.</li> </ul><p>With the Ruisdael stations currently confined to land, plans are being developed to install additional station on the North Sea, making use of the proliferation of wind farms in a co-creative setting of the scientific and industrial communities.</p>
