					<description><![CDATA[Three ground-based spectrometers in Germany and two satellite instruments simultaneously recorded a quasi 26-day temperature oscillation with amplitudes up to about 20 kelvin in the mesopause region during winter 2016/2017, which the authors identify as the first reported such strong Rossby (1,4) normal mode wave in the Northern Hemisphere middle atmosphere.]]></description>
