This was done using a merging approach developed in the framework of the European Space Agency's (ESA's) Climate Change Initiative Ozone project.   Firstly, the separate pixel-based level-2 observation - produced by the GOME-type Direct FITting v4 retrieval algorithm (GODFIT) are converted into level-3 products per sensor i.e. daily and monthly averages on a regular grid of 1x1 degree in latitude and longitude.  Before the individual level-3 data records are finally merged into one single product, adjustments are applied in order  to minimize possible inter-sensor biases and/or temporal drifts. Due to its notable long-term stability one sensor (OMI/Aura) was selected to serve as a reference for the other instruments,  which are then adjusted in terms of a correction that depends on latitude and time. A detailed description of the merging approach, the generation, and the geophysical validation of GTO-ECV is provided in Coldewey-Egbers et al. (2015, 2022), Garane et al. (2018) and Lambert et al. (2022).","keywords":"","inputDescription":null,"outputDescription":null,"softwareReference":null,"identifier_set":[]}],"acquisitionComponent":[{"ob_id":42314,"independentInstrument":[],"instrumentplatformpair_set":[{"ob_id":13964,"platform":"https://catalogue.ceda.ac.uk/api/v2/platforms/7813/?format=json","instrument":"https://catalogue.ceda.ac.uk/api/v2/instruments/2747/?format=json","relatedTo":{"ob_id":42314,"uuid":"65cdb261d5714d62a1267132a797cdf2","short_code":"acq"}},{"ob_id":13965,"platform":"https://catalogue.ceda.ac.uk/api/v2/platforms/846/?format=json","instrument":"https://catalogue.ceda.ac.uk/api/v2/instruments/8029/?format=json","relatedTo":{"ob_id":42314,"uuid":"65cdb261d5714d62a1267132a797cdf2","short_code":"acq"}},{"ob_id":13966,"platform":"https://catalogue.ceda.ac.uk/api/v2/platforms/3883/?format=json","instrument":"https://catalogue.ceda.ac.uk/api/v2/instruments/4119/?format=json","relatedTo":{"ob_id":42314,"uuid":"65cdb261d5714d62a1267132a797cdf2","short_code":"acq"}},{"ob_id":13967,"platform":"https://catalogue.ceda.ac.uk/api/v2/platforms/8207/?format=json","instrument":"https://catalogue.ceda.ac.uk/api/v2/instruments/8208/?format=json","relatedTo":{"ob_id":42314,"uuid":"65cdb261d5714d62a1267132a797cdf2","short_code":"acq"}},{"ob_id":13968,"platform":"https://catalogue.ceda.ac.uk/api/v2/platforms/8299/?format=json","instrument":"https://catalogue.ceda.ac.uk/api/v2/instruments/8208/?format=json","relatedTo":{"ob_id":42314,"uuid":"65cdb261d5714d62a1267132a797cdf2","short_code":"acq"}},{"ob_id":13969,"platform":"https://catalogue.ceda.ac.uk/api/v2/platforms/32134/?format=json","instrument":"https://catalogue.ceda.ac.uk/api/v2/instruments/8208/?format=json","relatedTo":{"ob_id":42314,"uuid":"65cdb261d5714d62a1267132a797cdf2","short_code":"acq"}}]}],"identifier_set":[],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/203914/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/203915/?format=json"]}
