Paper Abstract

At ALOMAR (Arctic Lidar Observatory of Middle Atmosphere Research, 69°N, 16°E) an exemplary co-location of tropospheric Lidar, sun-photometer and VHF Radar is used for aerosol investigations. Recently the University of Oslo, the Norwegian Institute for Air Research and the Andøya Rocket Range started to operate a new troposphere Lidar system. The system uses two elastic backscatter channels (1064nm, 355 nm), two polarization channels (532p nm and 532s nm) and a Raman channel (387nm). The co-located sun photometer is of Cimel type and the VHF Radar is operating at 53 MHz. The data from the Cimel instrument are collected in cooperation with a group from Valladolid (Spain) and the Radar is operated by the Institute for Atmospheric Physics from Kühlungsborn. The location of ALOMAR, north of the Arctic Circle and on an island, a few hundred meters from seashore and about 30 km off the continent, makes it ideal for investigations related to Sub-Arctic aerosols. The present paper presents the first results from simultaneous and collocated tropospheric measurements. We compare aerosol stratification derived from Lidar data with simultaneous measurements of total aerosol content, derived from Cimel data in dependence of simultaneous winds, stratified layers and echo power from radar data. Diurnal cycles for both summertime and wintertime are shown.
