| Zusammenfassung |
| A modified UFT-M version of the ultrafast airborne thermometer UFT, aimed at
in-cloud temperature measurements, was designed for the Physics of
Stratocumulus Top (POST) field campaign. Improvements in its construction
resulted in the sensor's increased reliability, which provided valuable
measurements in 15 of the 17 flights. Oversampling the data allowed for the
effective correction of the artefacts resulting from the interference with
electromagnetic transmissions from on-board avionic systems and the thermal
noise resulting from the sensor construction. The UFT-M records, when
averaged to the 1.4 and 55 m resolutions, compared to the similar records of
a thermometer in a Rosemount housing, indicate that the housing distorts even
low-resolution airborne temperature measurements. Data collected with the
UFT-M during the course of POST characterise the thermal structure of
stratocumulus and capping inversion with the maximum resolution of
~1 cm. In this paper, examples of UFT-M records are presented and
discussed. |
