Dataset
TEMP records collected by the Met Office MetDB System
Abstract
TEMP records describes measurements reported up to four times daily by radiosondes at worldwide fixed land stations. The radiosondes measure parameters such as atmospheric pressure, temperature, humidity, and wind speed and direction. The data are measured from the surface to approximately 20-30 km, and measurements are usually taken every 2 seconds. These data are provided from the Met Office as-is requiring each message part to be brought together to form each profile.

| 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.

| File Format: |
Data availability and file format
The 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. |
More Information (under review)
The TEMP dataset contain the following observations:
The data comprise vertical profiles of temperature, dew-point temperature, wind speed and wind direction at standard and significant pressure levels. The standard pressure levels are 1000, 925, 850, 700, 500, 400, 300, 250, 200, 150, 100, 70, 50, 30, 20 and 10 mb. Significant pressure levels are calculated according to the Met Office criteria and constitute levels at which significant events occur in the profile, e.g temperature inversions.
The data are measured from the surface to approximately 20-30 km. Generally there are 4 ascents per day from each station.
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.
The data are held in the BADC-CSV file format, each of which will contain one or more data records and are comma separated variables.

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.
Details of the WMO Meteorological codes used at weather observing stations (daily and hourly weather) explain the codes used in this dataset further.
The Met office Fact Sheet #13 – Upper Air Observations gives further information as to the data collected by radiosondes, which may then be stored in the TEMP data folder within the MetDB dataset at the BADC.
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.
