CATALOGUE OF ANTARCTIC CLIMATE DATA

ITALY

INTRODUCTION

The Italian Government signed the Antarctic Treaty in 1981. In 1985, the Italian National Antarctic Research Program (PNRA) was set up, thanks to Law 284 approved by Paliament. Following the enactment of Law 2284, ten scientific expeditions were completed and a permanent station was set up at Terra Nova Bay, on the western coast of the Ross Sea. During the first expedition, an Automatic Weather Station was set up nearby the base. At present, nine AWS's and one upper air rawinsonde system are operated by PNRA. In addition, several research programs concerning atmospheric physics and climatology have been started. PNRA is now organised in 19 'Projects'. The Projects that collect data that might be of interest for the climatological community are the following:

WEATHER

Weather observations are based on automatic weather stations. During summer, when Terra Nova Bay Station is manned, regular synoptic observations are carried on. The period of time during which the Base is inhabited varies from year to year, typically ranging from late October to late February. The following table describes the data available from AWS's. These data are validated and readily available. Data from synoptic observations and upper air (summer only) are being processed at present.
