International Arctic Systems for Observing the Atmosphere (IASOA) is a dynamic organization developed to
enhance Arctic atmospheric research by fostering collaborations among researchers during the International
Polar Year (IPY) and beyond. The member stations are Abisko, Sweden; Alert and Eureka, Canada; Barrow, USA;
Cherskii and Tiksi Russia; Ny-Ålesund, Norway; Pallas and Sodankylä, Finland; and Summit, Greenland. All of
these observatories operate year-round, with at least minimal staffing in the winter months, are intensive and
permanent.
Presently, measurement and building upgrades are occurring at the Tiksi, Eureka, Summit and Barrow
observatories. A new weather station building has been completed in Tiksi and is currently available for
installation of instruments. A second Clean Air Facility (CAF) that will be suitable for aerosol, chemistry, pollutant,
greenhouse gases, fluxes and radiation measurements is expected to be completed in the spring of 2008. Real-
time continuous measurement instruments for the measurement of ozone and black carbon, and flasks for
carbon cycle gas measurements for the new Tiksi station are awaiting shipping from Boulder, CO.
At the Eureka site many instruments including a flux tower, several CIMELs for the Aeronet Network, and a
Baseline Surface Radiation Network (BSRN) station were installed in the summer of 2007. With IPY funding the
level of technical support at the site has been increased to provide more reliable data collection and
transmission.
The Summit, Greenland observatory has recently released a strategic plan highlighting climate sensitive year-
round observations, innovative research platforms and operational plans to increase renewable energy to
maintain the pristine platform. Summit also has a new multi-channel GC/MS for continuous measurement of
trace halocarbon and CFC gas concentrations. All NOAA instruments have been moved from the Science trench
to a new atmospheric watch observatory building. NOAA is now manning the site for the 9-month winter season
of the year.
The Barrow observatory has two new systems for aerosol size and chemistry composition, as well as new POPs
measurements. The meteorology measurement and data system has been completely upgraded.
Current IASOA activities include the development of a web site (www.iasoa.org) that will serve as the "go-to" site
for atmospheric Arctic researchers to obtain information about the member observatories. Information posted for
each station includes a general overview of the observatory, a listing of available measurements and principle
investigators, links to data bases, and station contacts. These pages will help Arctic researchers find the data
they need to complete their research. The development of these observatory web pages, plus an "observatories-
at-a-glance" page, has allowed us to identify gaps in atmospheric measurements in the Arctic.
