A-TReC: Atlantic-THORPEX Regional Campaign (A-TReC)

2003

The North Atlantic THORPEX Regional Campaign (A-TReC) is a new international experiment which could change the way the weather is observed and forecast. By targeting the observations in areas where they are specifically needed THORPEX* hopes to improve the accuracy of forecasts – especially of weather systems which are particularly difficult to track.

The A-TReC is planned as a field campaign to make a significant contribution towards this common goal. The primary aim of the A-TReC is to test the real-time quasi-operational targeting of observations using a number of platforms (including AMDAR, ASAP ships, extra radiosonde ascents, research aircraft and meteorological satellites). To do this, it is necessary to identify suitable cases for targeting, provide information on the location of sensitive areas, and have the facilities to deliver extra observations within these areas at short notice. The ATReC will be the first time that the real-time adaptive control of such a complex set of observing platforms has been attempted. It is considered to be an essential preparation or 'proof of concept' for future targeting field campaigns. Additional scientific objectives of the ATReC will contribute to the understanding of the location and predictability of sensitive areas and the impact of targeted observations on forecast performance [and the benefit of potential new observing platforms].

The A-TReC will form one of three THORPEX Regional Campaigns (TReCs) planned during 2003/2004. The purpose of these TReCs is to test and evaluate experimental and operational remote sensing and in-situ observing systems, including (where feasible) their impact on data-assimilation, forecasts and user products.
