Met Office MetDB system: Surface, upper air and satellite data

Status: Not defined
Publication State: published

Abstract

Observational data extracted from the Met Office's MetDB system. Data include surface and upper air observations and some satellite data. These data are from a number of different message types covering data from land and ship surface data measurements through to upper air observations from wind profilers, radiosonde ascents and aircraft measurements and also satellite measurements.

Introduction

The MetDB data held in the BADC archives are a selected sub-set of observational data extracted from the MetDB system of the Met Office. These data are from a number of different message types covering data from land and ship surface data measurements through to upper air observations from wind profilers, radiosonde ascents and aircraft measurements and also satellite measurements.

Data arrive at the Met Office as per standard messages transmitted from source (e.g. SYNOP, METARS, TEMP message types) and are then decoded within the MetDB system. The BADC receives a text output from the MetDB system of these deciphered messages which are then processed into the BADC-CSV format. Messages are split up by observation date at this stage. METARS and CLIMAT data are not decoded by the Met Office and are stored at the BADC as per the original message. Details about the contents of each message type are given in the links from the relevant table entry further down this page. "Raw" data for all message types are available through the /raw folder within the archive. Each raw file contains messages received within a given period of time at the Met Office and are not sorted by observation date.


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. 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.


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.

The following message types are available through the BADC. Follow the links to see the appropriate table detailing the elements within each message type:

Message Name Description & Link
AMDARs Aircraft Meteorological Data Relay
LNDSYN Land based SYNOP messages
RASS Radio Acoustic Sounding System messages
SHPSYN Ship based SYNOP messages (including buoy and fixed platform)
WINPRO Wind profiler observations

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.

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:
