Summer sudden Na number density enhancements measured with the ALOMAR Weber Na Lidar
2008
Annales Geophysicae
<p><strong>Abstract.</strong> We present summer Na-densities and atmospheric temperatures measured 80 to 110 km above the Arctic Lidar Observatory for Middle Atmosphere Research (ALOMAR). The Weber Na Lidar is part of ALOMAR, located at 69&deg; N in Norway, 150 km north of the Arctic Circle. The sun does not set here during the summer months, and measurements require a narrowband Faraday Anomalous Dispersion Optical Filter (FADOF). <br><br> We discuss an observed sudden enhancement in the
