The Atmospheric Carbon-dioxide Grating Spectrometer (ACGS) instrument is pushbroom spectrometer operating in NIR and SWIR bands which allows the measuring of CO2 mole fraction.

The available ACGS products have a temporal coverage between March 2017 and January 2020 (not all days included in the time frame):

  • L1A DS: Sample Dark Calibration sample product
  • L1A GL: Sample Glint Sample products
  • L1A LS: Sample Lamp Calibration sample product
  • L1A ND: Principal-Plane Nadir Sample product
  • L1A ZS: Sample Z-Axis Solar Calibration Sample
  • L1B CAL DS: Sample Dark Calibration product
  • L1B CAL LS: Sample Lamp Calibration product
  • L1B CAL ZS: Sample Z-Axis Solar Calibration product
  • L1B SCI GL: Sample Glint Science product
  • L1B SCI ND: Principal-Plane Nadir Science product.


The Cloud Aerosol Polarization Imager (CAPI) is a pushbroom radiometer in VIS, NIR and SWIR bands for the observation of aerosols and clouds optical properties.

The CAPI products are available in a time range from July 2019 and January 2020 (not all days included in the time frame):

  • L1A ND: Principal-Plane Nadir product
  • L1B ND 1000M: Principal-Plane Nadir products at 1000 m resolution (1375 nm, 1640 nm)
