Daily composites of measurements of the integral NO2 content in the atmosphere obtained with the TROPOMI (TROPOspheric Monitoring Instrument) spectrometer were processed. The data source was the IKI-Monitoring Collective Use Center (http://ckp.geosmis.ru/). The processing resulted in daily global fields of the integral NO2 content without data gaps and horizontal gas transport vectors on a regular 0.25×0.25° grid. Contextual image filling methods were used to fill in missing data within the daily global field. Optical flow estimation methods were used to reconstruct the horizontal dynamics. The data were processed for the period from May 1, 2018, to August 31, 2025, and will be presented as a product at the IKI-Monitoring Collective Use Center.
Keywords: nitrogen dioxide, horizontal dynamics, satellite monitoring, shared use center, TROPOMI
