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 also the coordinated study of atmospheric variability at all time scales. The measurement program of the 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. The first global NDMC campaign was conducted from September 01 to October 31, 2009. In the study presented the rotational temperature data measured by ground-based instruments at the NDMC stations Maimaga (63.0N, 129.5E), Zvenigorod (55.7N, 36.8E), Wuppertal (51.3N, 7.2E), Oberpfaffenhofen (48.1oN, 11.3oE), Hohenpeissenberg (47.8N, 11.0E), Schneefernerhaus (47.4N, 11.0E), Sierra Nevada (37.1N, 3.4W), El Leoncito (31.8S, 69.3W), and Davis (68.6S, 78.0E) as well as satellite-based temperature measurements of TIMED/SABER are analysed with respect to planetary wave activity. The analysis is based on different spectral analyses (e.g. harmonic analysis) and Hofmueller diagrams.
