| Zusammenfassung |
| Measurement of atmospheric temperature as a function of pressure,
T(P), is key to understanding many atmospheric processes and
a prerequisite for retrieving gas mixing ratios and other parameters
from solar occultation measurements. This paper gives a brief overview
of the solar occultation measurement technique followed by a detailed
discussion of the mechanisms that make the measurement sensitive to
temperature. Methods for retrieving T(P) using both broadband
transmittance and refraction are discussed. Investigations using
measurements of broadband transmittance in two CO2 absorption
bands (the 4.3 and 2.7 μm bands) and refractive bending are
then presented. These investigations include sensitivity studies,
simulated retrieval studies, and examples from SOFIE. |
