Monthly Tropical Stratospheric Zonal Winds from Radiosondes

\n

Data Source and Processing:

\n

Monthly mean zonal wind data for the tropics are provided as a service for the global QBO and trend analysis communities. The original data source and processing chain were established by the Free University of Berlin (FUB). Currently, the data is processed at the Karlsruhe Institute of Technology (KIT, ROR:04t3en479), Institute of Meteorology and Climate Research (IMK), Germany with the tools developed at FUB.

\n

Data Description:

\n

The dataset includes monthly mean zonal wind values at pressure levels 100, 90, 80, 70, 60, 50, 45, 40, 35, 30, 25, 20, 15, 12, and 10 hPa, derived from radiosonde observations at four equatorial stations:

ABOUT THE DATAHUB

\n

The DataHub of the Research Field Earth and Environment is a joint initiative of all centers of the Helmholtz Association participating in the research program 'Changing Earth'. Three SubHubs (ATMO, MARE and TERRA) assigned to the compartments of the Earth system jointly form the DataHub.

\n

The DataHub brings together the (Earth system) data in the research area Earth and Environment. This process requires a consistent implementation of the FAIR principles and opens the data to the outside (openness).

\n

It thus represents an offer to all researchers and other users of the data to gain new insights.

\n

Within the DataHub, data management tools are developed and made available, and data products are offered in thematic viewers. The continuous and long-term development process of these solutions is the DataHub's task. Furthermore, networking of the DataHub with other national (e.g. NFDI) and international initiatives (e.g. EOSC, RDA) takes place.

\n

The publications listed here in Zenodo only represent a small part of alle DataHub-publications. More publications can be found via our Earth Data portal.
