This study introduces a space-based instrument for measuring atmospheric temperature and wind. Simulations show it is suitable for most conditions, despite potential errors from small-scale atmospheric structures.
Area of Science:
- Atmospheric science
- Optical physics
- Remote sensing technology
Background:
- Accurate measurement of atmospheric temperature and wind is crucial for weather forecasting and climate modeling.
- Existing remote sensing techniques face limitations in spatial and temporal resolution.
Purpose of the Study:
- To describe a novel space-based instrument, the tempo-spatially modulated polarization atmosphere Michelson interferometer (TSMPAMI).
- To present the interferogram acquisition method for the TSMPAMI.
- To evaluate the instrument's capability in deriving atmospheric temperature and horizontal wind data.
Main Methods:
- Utilizing the relative motion between the TSMPAMI and target to modulate optical path difference.
- Acquiring interferograms through the described method.
- Performing simulations to analyze measurement errors for atmospheric parameters.
Main Results:
- The TSMPAMI successfully derives atmospheric temperatures and horizontal winds from optical observations.
- Simulations indicate measurement errors are influenced by scene mismatch in adjacent CCD sub-areas for small-scale atmospheric structures.
- The instrument demonstrates suitability for atmospheric parameter measurement under most realistic orbital and atmospheric conditions.
Conclusions:
- The developed TSMPAMI is a viable instrument for space-based atmospheric remote sensing.
- Understanding error sources related to orbital velocity and exposure time is key for data interpretation.
- The instrument shows promise for advancing atmospheric science research and applications.
