In Situ VTOL Drone-Borne Observations of Temperature and Relative Humidity over Dome C, Antarctica
نویسندگان
چکیده
The Antarctic atmosphere is rapidly changing, but there are few observations available in the interior of continent to quantify this change due ground stations and satellite measurements. Concordia station located on East Plateau (75° S, 123° E, 3233 m above mean sea level), one driest coldest places Earth. Several remote sensing instruments at probe atmosphere, together with operational meteorological sensors. In order observe situ clouds, temperature, relative humidity supercooled liquid water (SLW) a high vertical resolution, new project based use an unmanned aerial vehicle (drone) take-off landing from DeltaQuad Company has been set up Concordia. A standard Vaisala pressure, temperature sensor was installed aboard drone coupled Anasphere SLW sensor. total thirteen flights were conducted 24 December 2022 17 January 2023: nine technology four science (on 2, 10, 11 13 2023). Drone-based profiles compared (1) balloon-borne 12:00 UTC, (2) ground-based microwave radiometer HAMSTRAD (3) outputs numerical weather prediction models ARPEGE AROME. No clouds present during period observations. Despite technical issues operation harsh environments encountered (altitude, geomagnetic field), drone-based consistent humidity. showed systematic negative bias 2 °C, two were, lowermost troposphere, systematically warmer (by 2–4 °C) moister 10–30%) than Our study shows great potential very resolution (a meters).

Brightness and Extinction at Dome C , Antarctica
The recent discovery of exceptional seeing conditions at Dome C, Antarctica, raises the possibility of constructing an optical observatory there with unique capabilities. However, little is known from an astronomer's perspective about the optical sky brightness and extinction at Antarctic sites. We review the contributions to sky brightness at high-latitude sites, and calculate the amount of us...

متن کاملSubmillimeter Site Testing at Dome C, Antarctica
We have developed a 350μm radiometer to perform automated site testing in remote regions of Antarctica. In summer 2000–2001 the instrument operated at Concordia, a new station under construction at Dome C on the Antarctic Plateau. We present the results, and compare them with the atmospheric opacity measured at the South Pole in the same five-week period. During these five weeks, observing cond...
متن کاملEnvironmental chamber for in situ dynamic control of temperature and relative humidity during x-ray scattering.
We have designed, constructed, and evaluated an environmental chamber that has in situ dynamic control of temperature (25 to 90 °C) and relative humidity (0% to 95%). The compact specimen chamber is designed for x-ray scattering in transmission with an escape angle of 2θ = ±30°. The specimen chamber is compatible with a completely evacuated system such as the Rigaku PSAXS system, in which the s...
