Directory entires that have specified Dirigibile Italia, Ny-Ålesund as one of the geographic regions for the project/activity and are included in the AMAP, ENVINET, SAON and SEARCH directories. Note that the list of regions is not hierarchical, and there is no relation between regions (e.g. a record tagged with Nunavut may not be tagged with Canada). To see the full list of regions, see the regions list. To browse the catalog based on the originating country (leady party), see the list of countries.

The 2003 field activity will be mainly dedicated to coring activity which includes: 1. the sampling of snow and ice cores from a Ny-Ålesund nearby glacier (midre Lovenbreen). 2. the collection of near coast (Kongsfjorden) and lakes sediments (maximum under pack depth 30 m). Sampling collection of ice and sediment cores will be performed using a portable, electric operated, sampling corer. The transport of all materials up to each sampling station should be performed with snowcats.
Specific objectives of the proposal are: 1. the determination of the cloud coverage by means of a simple methodology based on radiometric measurements; 2. the determination of the radiative forcing produced by different type of cloud and coverage for applications into GCM’s as ‘cloud parameterisations’. The results will be obtained for two different radiative regimes by means of different experimental campaigns.
