Sentinel-5p and Suomi NPP tracks

An important feature of the SENTINEL-5P mission is the synergistic exploitation of simultaneous measurements of imager data from the Visible/Infra-red Imager and Radiometer Suite (VIIRS), embarked on the Suomi-NPP (National Polar-orbting Partnership) satellite of NASA/NOAA (NPP mission started in 28 October 2011). The SENTINEL-5P orbit is selected such that it trails behind Suomi-NPP by 3.5 minutes in Local Time Ascending Node (LTAN), allowing the SENTINEL-5P observation swath to remain within the scene observed by Suomi-NPP.
