Minimize Mission Objectives

SENTINEL-5P mission, as a part of the COPERNICUS space component programme, is intended to provide reliable and up-to-date information about the Earth's atmosphere. This information will be accessible via COPERNICUS services such as the ‘atmosphere monitoring service' or the ‘climate change service'. Decision makers will use it in order to take the right actions on environmental policies from which depends the well-being and security of EC citizens and future generations.

The overall TROPOMI/SENTINEL-5P mission objective can be defined as:

"to measure the troposphere with sensitivity down to the Earth's surface, for scientific research and in support of services to society, with sufficiently high spatio-temporal resolution to quantify anthropogenic and natural emissions and atmospheric life cycles of the main tropospheric pollutants (O3, NO2, CO, HCHO and SO2) and two major greenhouse gases (tropospheric O3 and methane (CH4)). In addition, aerosol particles will be monitored, which impact on air quality and climate forcing from the regional to the global scale".(ref: Science Requirements Document for TROPOMI, Volume I, Mission and Science Objectives and Observational Requirements)

With launch scheduled for 2017, the mission is intended to reduce gaps in the availability of global atmospheric data products between SCIAMACHY/Envisat (which ended in April 2012), the OMI/AURA mission and the future SENTINEL-5 and SENTINEL-4 missions.

TROPOMI/SENTINEL-5P combines the strengths of SCIAMACHY, OMI and state-of-the-art technology to provide observations with performances that cannot be met by the current instruments in space. Performance of current in-orbit instruments will be surpassed in terms of sensitivity, spectral resolution, spatial resolution and temporal resolution.
