SPEXone-SG
Project Instruments
SPEXone-SG is a compact multi-angle spectropolarimeter for the quantification of atmospheric aerosol. The instrument is a copy of the SPEXone instrument for NASA’s PACE, but with an increased across-track swath of the telescopes of 250 km on the ground. Mission implementation for SPEXone-SG is still under development.
The telescopes look 50 and 20 degrees forward and backward, and straight down (nadir). Special Polarization Modulation Optics modulate the spectral intensity according the state of linear polarization. Each spectrum is then split in two polarizations and the ten modulated spectra are created in the spectrometer and projected on one CMOS detector array.

Project
TROPOMI
The Dutch Tropospheric Monitoring Instrument (TROPOMI) is flying onboard the Copernicus Sentinel-5p mission, launched in 2017. Every day it scans the entire globe for e.g. methane and carbon monoxide concentrations at city-scale level.
