Nagai, T., Uchino, O., Itabe, T., Shibata, T., Mizutani, K. and Fujimoto, T. (1997). Polar stratospheric clouds observed at Eureka (80°N, 86°W) in the Canadian Arctic during the 1994/1995 winter. Geophysical Research Letters 24: doi: 10.1029/97GL02094. issn: 0094-8276.

A lidar system was installed at Eureka (80 ¿N, 86 ¿W) in January 1993 to monitor stratospheric aerosols and polar stratospheric clouds (PSCs). In the winter of 1994/1995, PSCs were found at altitudes of around 20 km in the middle of December. In early January 1995, PSCs were observed at altitudes from 14.3 km to 16 km, where the temperature ranged from 199 K to 202 K. Since this range is higher than the frost point of nitric acid trihydrate (NAT), the particles in these PSCs may have consisted of sulfuric acid tetrahydrate (SAT).¿ 1997 American Geophysical Union
