Abstract
Abstract. Downwelling and upwelling shortwave and longwave radiation components from six active polar sites, taking part of the Baseline Surface Radiation Network (BSRN), were selected for the period of the last International Polar Year (March 2007 to March 2009), and included in the BSRN-IPY dataset, along with metadata and supplementary data for some of the stations. Two sites, located at Svalbard archipelago (Ny Ålesund) and Alaska (Barrow), represent Arctic sea-level conditions. Four Antarctic stations represent both sea-level (Dronning Maud Land and Cosmonaut Sea) and high-elevation conditions (South Pole and East Antarctic Plateau). The BSRN-IPY dataset content and quality are discussed. The dataset is now available at doi:10.1594/PANGAEA.737668, and can be used for free after accepting the BSRN data release guidelines. The dataset has been summarized as monthly averages and subject to further evaluation according to strict criteria not previously applied.
Highlights
The radiative energy budget at the surface plays a fundamental role in defining the thermal conditions and drives the general circulation of the earth-atmosphere system, shaping the main characteristics of the earth’s climate
A working group entitled Cold Climate Issues was established during the 10th Baseline Surface Radiation Network (BSRN) Scientific Review and Workshop held in De Bild (Netherland) during 2008, in order to address and minimize the impact of these problems in BSRN polar data (Dutton, 2008)
The dataset is composed of a subset of monthly files archived in the World Radiation Monitoring Center (WRMC) – the central archive of the BSRN – hosted at Alfred Wegener Institute
Summary
The radiative energy budget at the surface plays a fundamental role in defining the thermal conditions and drives the general circulation of the earth-atmosphere system, shaping the main characteristics of the earth’s climate. The BSRN provides accurate measurement of surface radiation fluxes collected at 51 sites around the world. Four high latitude sites have operated since BSRN was established in 1992 in both the Arctic (Ny Ålesund and Barrow) and the Antarctic (Amundsen-Scott and Neumayer). A working group entitled Cold Climate Issues was established during the 10th BSRN Scientific Review and Workshop held in De Bild (Netherland) during 2008, in order to address and minimize the impact of these problems in BSRN polar data (Dutton, 2008). In this paper we highlight certain observational and data evaluation issues specific to the extreme polar conditions
