Summary
The Network for the Detection of Mesopause Change (NDMC) is a global program with the mission to promote international cooperation among research groups investigating the mesopause region (80-100 km) with the goal of early identification of changing climate signals. This program involves the coordinated study of atmospheric variability at all time scales, the exchange of existing know-how, and the coordinated development of improved observation, analysis techniques and modeling. The initial emphasis is on mesopause region airglow techniques utilizing the existing ground-based and satellite measurement capabilities. The measurement program of NDMC has been established including operational and campaign-based activities. There will be regular global NDMC campaigns once a year usually at the equinox period. From September 01 to October 31, 2009, the first global NDMC (Network for the Detection of Mesopause Change) measurement campaign has been conducted. In the study presented the OH* temperature data measured by ground-based instruments at the NDMC stations Maimaga (63.0°N, 129.5°E), Zvenigorod (55.7°N, 36.8°E), Wuppertal (51.3°N, 7.2°E), Oberpfaffenhofen (48.1ºN, 11.3ºE), Hohenpeissenberg (47.8°N, 11.0°E), Schneefernerhaus (47.4°N, 11.0°E), Sierra Nevada (37.1°N, 3.4°W), El Leoncito (31.8°S, 69.3°W), and Davis (68.6°S, 78.0°E) are analysed with respect to planetary wave activity. Based on the nightly means, time series of OH* temperature fluctuations for each station on temporal scales of 3 to 20 days are investigated
