Downloading, cleaning and aggregation of NO2 (Nitrogen Dioxide) datas from the European satellite Sentinel5. This work is being carried out as part of the AMSECovid19 project.

MAJOR UPDATE : Complete overhaul of the file structure. Addition of a powerful logging system and a progressbar. Optimization of the code.

Increase of ~30-50% in file size and processing time, with the benefit of less RAM required and new information essential for data processing: Wind angle, surface altitude, number of observations, snow/ice flag, soil classification, quality decreased to > 0.5, surface pressure...

Change of the data source: ONDA DIAS imposed a restrictive archiving system. We now use CREODIAS.
