AMAP Project Directory
The AMAP Project Directory (AMAP PD) is a catalog of projects and activities that contribute to assessment and monitoring in the Arctic. The Arctic Monitoring and Assessment Programme (AMAP), is a working group under the Arctic Council, tasked with monitoring and asessing pollution, climate change, human health and to provide scientific advice as a basis for policy making.
The directory, which is continously updated, documents national and international projects and programmes that contribute to the overall AMAP programme, and provides information on data access as well as a gateway for the AMAP Thematic Data Centres.
Other catalogs through this service are ENVINET, SAON and SEARCH, or refer to the full list of projects/activities.

- 1. Investigations of tropospheric aerosols by lidar
-
A tropospheric lidar system with a Nd:YAG-Laser was installed at the Koldewey-Station in 1998. It operates at a laser wavelengths of 355, 532, and 1064 nm with detection at 532 nm polarised and depolarised, and at Raman wavelengths like 607nm (nitrogen). It records profiles of aerosol content, aerosol depolarisation and aerosol extinction. During polar night the profils reach from the ground up to the tropopause level, while during polar day background light reduces the altitude range. The main goal of the investigations is to determine the climate impact of arctic aerosol. Analysis of the climate impact will be performed by a high resolution regional model run at the Alfred Wegener Institute (HIRHAM). The lidar system is capable to obtain water vapour profiles in the troposphere. Water vapour profiles are crucial for the understanding of the formation of aerosols. The water vapour profiles are also used for the validation of profiles measured by the CHAMP satellite from 2001 onwards.
