enewable energy and maintain the pristine platform.<br />

Summit also has a new multi-channel gas chromotograph/mass<br />

spectrometer (GC/MS) for continuous<br />

measurement of trace halocarbon and CFC gas concentrations.<br />

All NOAA instruments were moved from<br />

the science trench to a new atmospheric watch observatory<br />

building.<br />

The Barrow observatory has two new systems<br />

for measurements of aerosol size and chemistry<br />

composition, as well as persistent organic pollutants<br />

(POPs). The meteorological measurements and data<br />

system has been completely upgraded.<br />

Current IASOA activities include the development<br />

of a web site (www.iasoa.org) that will serve as the<br />

“go-to” site for atmospheric Arctic researchers to obtain<br />

information about the member observatories.<br />

Information posted for each station includes a general<br />

overview of the observatory, a listing of available<br />

measurements and principal investigators, links to<br />

data bases and station contacts. These pages will help<br />

Arctic researchers find the data they need to complete<br />

their research. The development of these observatory<br />

webpages and the “observatories-at-a-glance” page<br />

has allowed us to identify gaps in atmospheric measurements<br />

in the Arctic (detailed information on this<br />

project is also given in Chapter 3.4).<br />

Climate System of Spitsbergen (SCSCS<br />

no. 357): Intercomparison and analysis of<br />

radiation data obtained by Russian and<br />

Norwegian standard radiation sensors<br />

at Barentsburg and Ny-Alesund research<br />

stations<br />

Joint analysis of historical and current data<br />

of radiation observations obtained in different<br />

countries indicates a need for comparing readings<br />

of instruments. This is especially true for the Russian<br />

and Norwegian stations on Svalbard (Spitsbergen).<br />

From the beginning of regular Russian radiation<br />

measurements on Svalbard (Barentsburg settlement),<br />

the observation program has used standard Russian<br />

sensors (Yanishevsky-Savinov pyranometers M-80 or<br />

M-115M). All radiation measurements carried out on<br />

the research stations of other countries involved in<br />

polar research (Norway, Germany, Italy, U.K., U.S.A.,<br />

China, Republic of Korea and France) are compactly<br />

located in the Norwegian settlement Ny-Alesund<br />

(Kings Bay) and combined into one common network<br />

in the framework of the international “Kongsfjorden<br />

<strong>International</strong> Research Base” (Fig. 2.1-2).<br />

The incoming global, diffuse and reflective radiations<br />

are recorded separately. As a rule, the aforementioned<br />

countries use universal common measurement<br />
