Abstract: The DoCTOr (Dome C Tropospheric Observer) project aims to establish an integrated monitoring system to measure simultaneously, continuously and with a high temporal resolution the water vapor and temperature vertical profiles and the radiative exchanges vs. altitude.
The monitoring will enable us to detect both long-term trends and fast-evolving phenomena, the latter useful in the interpretation of the causes of the first.
This task is performed mainly through remote sensing techniques, allowing for the study of a highly unperturbed atmospheric sample.
The integration of all the deployed instrumentation in a single acquisition system simplifies greatly the data analysis needed to retrieve the final products: The REFIR-PAD spectroradiometer (already operating in dome C since 2011) will provide spectrally-resolved
atmospheric downwelling radiances in the mid to far-infrared spectral range, while a laser diode based profiler will characterize the microphysics state of the first 3 km of the atmosphere.
A real-time data analysis system based on an atmospheric radiative transfer model will then retrieve from the acquired data the temperature and water vapor profiles and the cloud optical thickness in almost all weather conditions found at Dome C, with a temporal resolution of about 10 minutes.
