ESA's SCISAT-1 satellite provides vertical profiles of atmospheric constituents from two instruments. The ACE-FTS Fourier Transform Spectrometer and MAESTRO dual-channel spectrometer measure trace gases, aerosols, temperature, and pressure via solar occultation to study ozone distribution in the upper troposphere and stratosphere. Data products are available as Level 2 data, with ACE-FTS at version 4.1 and MAESTRO at version 3.13.
Use Cases
- Modeling ozone distribution and depletion processes based on vertical profiles of O3, NO2, and BrO.
- Analyzing aerosol and cloud extinction in the stratosphere and troposphere based on MAESTRO spectral measurements.
- Studying polar ozone budget dynamics based on regional measurements from the ACE-FTS instrument.
- Retrieving atmospheric temperature and pressure profiles based on CO2 line measurements and solar occultation spectra.
Strengths
- Provides data from two complementary instruments: ACE-FTS and MAESTRO.
- ACE-FTS measurements are recorded every 2 seconds, providing fine temporal resolution.
- Retrieved results are interpolated onto a standardized 1 km vertical grid for consistency.
- MAESTRO uses two overlapping spectrometers (280-550 nm and 500-1030 nm) to improve stray-light performance.
