We're planning to retire the Community Data Portal (CDP) after nearly 15 years of service. The most active datasets will be migrated to the Climate Data Gateway website. We tentatively plan to shutdown the CDP service by Jan 31, 2018. Please contact us with questions or concerns.
Effective Atmospheric Angular Momentum (EAAM)
Publisher: GB/NCAS/BADC > British Atmospheric Data Centre, NERC Centres for Atmospheric Science, United Kingdom  [contact email: BADC AT rl.ac.uk]  [web page]
Summary: Atmospheric Angular Momentum (AAM) plays a significant role in causing variations in the length of day. Study of AAM can also yield information about the Earths orientation in space and the large scale behaviour of the atmosphere. The BADC stores AAM data from the Met Office and the European Centre for Medium Range Weather Forecasting (ECMWF). The data are available as ASCII files containing values of the 3 angular momentum components at 12 or 24-hourly intervals, from 1979 onwards and can be obtained via this World-Wide Web interface or by anonymous FTP.
