Abstract Project: AWIPEV_0001

Marion Maturilli (AWI)

The program of the AWIPEV Meteorological Observatory includes measurements of surface radiation as well as surface and upper-air meteorology. The radiation measurements are operated since 1992 in the frame of the Baseline Surface Radiation Network (BSRN), providing high quality data of all net surface radiation balance components. Close by, the meteorological surface data for pressure, air temperature, relative humidity and wind are obtained using a 10m weather mast. The surface-based observations are supplemented by a ceilometer providing cloud base height. To capture the vertical distribution of the meteorological parameters temperature, rel.humidity and wind, balloon-borne radiosondes are launched daily. The near-real time data of the soundings are transferred via Met.no to the global system for weather data to be used in numerical weather prediction and meteorological reanalyses. Furthermore, the AWIPEV radiosonde program is a certified datastream for the GCOS Reference Upper-Air Network (GRUAN). In April/May 2024, the new station personnel on site will be introduced to BSRN measurements, particularly to radio and ozone soundings with emphasis on GRUAN reference quality. The radiation sensors will be exchanged for calibration. The monitoring activities are operated throughout the year, with the daily check-up routine for the surface radiation and meteorology measurements, adding to the >25 year dataset of continuous radiation and meteorological measurements.
The maintenance stay will include the visit of one participant who is responsible for the similar instrumentation at the Antarctic Neumayer station, to ensure technical exchange and future similarity between the two AWI Meteorological Observatories.
