Minimize SciSat-1/ACE
Web Content Image

SciSat-1/ACE is an atmospheric science mission of Canada. Through a 3rd party mission agreement ESA will make validated data from the ACE-FTS (ACE-Fourier Transform Spectrometer) available. The FTS measures the vertical distribution of trace gases, in particular of the regional polar O3 budget, as well as pressure and temperature (derived from CO2 lines).
