Abstract:
From Oct. 2017 to August 2020 a field campaign at the Russian observatory “Icebase Cape Baranova” (79.280 N, 101.620 E) in the Laptev Sea area was carried out using SODAR measurements to investigate the atmospheric boundary layer. Data were collected continuously for almost three complete years. A SODAR (Sound Detection And Ranging) was installed in addition to the existing instrumentation at the observatory. A SODAR measures the Doppler signal of sound returns, which are used to derive vertical profiles of the wind speed, wind direction and the turbulence characteristics in the lower atmosphere. Sound pulses, emitted by the SODAR antenna, get backscattered at temperature inhomogeneities and then received by the same antenna (monostatic SODAR). SODAR measurements always contain information of an air volume. For the Scintec MFAS SODAR these air volumes have a dimension of 10 m in the vertical, and several meters horizontally depending on height. The Scintec MFAS SODAR emits at frequencies between 1650 HZ to 2750 Hz. The SODAR was installed about 400 m east of the main observatory, where the routine synoptic observations and radiosonde launches are performed.
The measurements were part of the BMBF funded projects “CATS” (grant 03F0776D) and “CATS-Synthesis” (grant 03F0831C). They were also endorsed as YOPP project CATS-BL and contribute to the Arctic YOPP SOPs Feb.-March 2018 July-Sept. 2018, and the Targeted Observing Periods (TOPs) during MOSAiC in 2019-2020.
