Summary
A brief description of the data.

This dataset holds Northern Hemisphere (north of 15 deg. N) daily and monthly series of 500 hPa geopotential height fields and also daily and monthly series of 1000-500 hPa thickness fields. The data is available for the period 1945 to 2005. The data is supplied by the Met Office, Hadley Centre.

Content
The actual data being described by this document. NB, in the case of data granules, this content may just be a reference to an ingested CSML or CDML file.

Introduction

This data set holds gridded (5° latitude by 10° longitude grid) Northern Hemisphere (north of 15° N) daily and monthly series of 500 hPa geopotential height fields and also daily and monthly series of 1000-500 hPa thickness fields. The data is available for the period 1945 to 2005.

Restricted Data Access

The Met Office wish to monitor the use of this data and require an acknowledgement of the data source if they are used in any publication. The online application for access to the Met Office Northern Hemisphere Geopotential Height data includes acceptance of the Met Office Conditions of Use. Please note that the Met Office data sets are available for bona fide academic research only (sorry no undergraduates), on a per person per project basis (i.e. all members on a same project who will be using the data must individually apply for access to the data). If you wish to access the Met Office data for commercial or personal purposes, please contact the Met Office directly.

Your application for accessing the Geopotential Height data will be processed within a day of receipt and you will receive a confirmation email. Provided your application is complete and fully meets the Met Office conditions, a web account will be activated to allow you access to the Geopotential Height data directories via your login account from the BADC WWW Browse Archive pages.

Please read the 00README file available under /badc/ukmo-height/ directory to to guide you through the tree structure and the data directory.

Data availability and file format

The data held at the BADC, are stored in a simple ASCII format (plain text and "human" readable).

More details about the file format are available from the BADC Documentation.

Who to contact

If you have queries about these pages or about obtaining the Met Office Geopotential Height data from the BADC then you should contact BADC Support. Your query should be answered within one working day. When follow-up work is required, the BADC support will carry out the work as quickly and efficiently as possible, and in any case, the user will be kept informed of progress.

Lineage
Summary of the origins of the dataset, e.g.: "Dataset produced from NASA MODIS instrument on Terra and collected at the University of York's groundstation 1999-2003 and a copy provided to NEODC in June 2007".

Data were prepared by the Met Office's Hadley Centre before a copy was obtained for archiving at the BADC.
