Dataset
Ozone Satellite Data, Part of the Met Office MetDB System
Abstract
The ozone satellite data describe ozone measurements deduced from satellite data. The dataset contains atmospheric profiles of ozone concentrations. The data are measured by satellites and around 2700 observations are made per day.

| Access rules: |
Restricted data: please submit an application using the REQUEST ACCESS link for access.
Use of these data is covered by the following licence: http://licences.ceda.ac.uk/image/data_access_condition/ukmo_agreement.pdf. When using these data you must cite them correctly using the citation given on the CEDA Data Catalogue record. |

| Data lineage: |
Data are extracted from the Met Office's "metDB" system and supplied to BADC. These are then processed to generate BADC-CSV files, where possible. METARS and CLIMAT message types are stored as original message types only within http://data.ceda.ac.uk/badc/ukmo-metdb/raw |
||||||||||||||
| Data Quality: |
Land and ship SYNOP messages undergo some quality control at the Met Office, but these messages are not as rigorously checked as they are within the MIDAS system into which the data are later migrated. Thus, for historic data the MIDAS dataset is the recommended dataset to use for surface observations.

Data availability and file format
Message Tables
The Met Office MetDB holds data from a variety of different message types covering observations from satellites, profiling instruments (e.g. radiosondes and wind profilers) and surface based observations (e.g land meteorological recording stations). The BADC has obtained access to an number of the message types that should be of greatest use to the atmospheric research community and the data are stored in a the BADC-CSV format, which is comma separated, plain text, "human" readable and self describing.
File FormatThe data are held in the BADC-CSV file format, each of which will contain one or more data records and are comma separated variables. "Metadata" are provided giving a full description of the content of the data. More information about the file format can be found on the BADC-CSV format page, which also contains two example files taken from the MetDB dataset. As the data are held as comma separated variable the file should load automatically into programmes such as Microsoft Excel. Alternatively see the following webguide on how to read a text file into Excel:

More Information (under review)
The ozone satellite data contain the following observations:
The solar elevation is measured in degrees, the total cloud cover is given to the nearest percentage, the pressures are given in pascals, and the densities are measured in kg per metre cubed.
The data is collected by an satellites, and around 2700 observations are made per day.
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. Their data is therefore restricted. The online application for access to the Met Office MetDB data includes acceptance of the Met Office Conditions of Use.
Please note that the Met Office data sets held at the BADC are available for bona fide academic research only. 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 dataset 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, your web account will be activated to allow you access to the Met Office MetDB data directories via your login account from the BADC WWW Browse Archive pages.

Details of the WMO Meteorological codes used at weather observing stations (daily and hourly weather) explain the codes used in this dataset further.
If you have queries about these pages or about obtaining the Met Office surface stations 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.
