| Zusammenfassung |
| Two types of temperature sensors are designed and tested: a thermocouple and
a fine wire resistance thermometer. The intention of this study is to figure
out which kind of measurement principle is in general more suited for
atmospheric boundary layer meteorology with small remotely piloted aircraft (RPA). The sensors are
calibrated in a NIST traceable climate chamber and validated in flight
against tower measurements, radiosondes and remote sensing. The sensors have
a measurement range of at least −10–50 °C, an absolute RMS
error of less than ±0.2 K which is stable over the lifetime of the
sensors, and a resolution of about 0.01 K. Both devices are tested for
typical errors like radiation error and adiabatic heating, as well as for
their dynamic response. Spectral resolutions of up to approximately 10 Hz
can be obtained with both sensors, which makes them suitable for turbulence
measurement. Their low cost of less than 100 EUR in pure hardware is a major
advantage for research with small RPA. |
