Observatory Upgrades<br />

Numerous instrument upgrades, new instrument<br />

installations and new programs occurred over the<br />

course of IPY at several of the IASOA observatories. A<br />

few examples follow.<br />

Eureka, Nunavut, Canada (80.050 N, 86.417 W, 10 m<br />

ASL (32.8 ft ASL))<br />

• A new flux tower (Fig. 3.4-8)<br />

• Several CIMEL sunphotometers for the Aeronet<br />

Network<br />

• A Baseline Surface Radiation Network (BSRN)<br />

station<br />

• Starphotometer<br />

• Precipitation sensor suite<br />

• VHF wind tracking radar<br />

• All sky imager<br />

• Spectral airglow temperature imager<br />

• The Canadian Network for the Detection of<br />

Atmospheric Change (CANDAC) Millimeter Cloud<br />

Radar (MMCR) replaced the National Oceanic and<br />

IASOA<br />

Atmospheric Administration (NOAA)/ Study of<br />

Environmental Arctic Change (SEARCH) MMCR.<br />

• Rayleigh-Mie-Raman lidar and a tropospheric<br />

ozone lidar<br />

• With IPY funding, the level of technical support at<br />

the site was increased to provide more reliable data<br />

collection and transmission<br />

• In addition to equipment upgrades, Eureka<br />

scientists hosted visiting diplomats as part of the<br />

“Northern Diplomatic Tour,” as well as Grade 11-<br />

12 students and teachers as part of the Northern<br />

Experience Program.<br />

Summit, Greenland (72.580 N, 38.48 W, 3238 m ASL<br />

(10623.4 ft ASL))<br />

• Summit observatory released a strategic plan<br />

highlighting climate sensitive year-round<br />

observations, innovative research platforms and<br />

operational plans to increase renewable energy<br />

to maintain the pristine platform. Summit also<br />

has a new multi-channel gas chromatograph for<br />
