The global CLIMAT upper air values from standard pressure levels data describe monthly values, at specified pressure levels, of atmospheric pressure, air temperature, geopotential height, wind steadiness factor, mean vector wind direction and dew point. The measurements are attained by observation stations worldwide and transmitted within FM 75-VI CLIMAT TEMP messages. The data span from 1946 to 2007.

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: When using these data you must cite them correctly using the citation given on the CEDA Data Catalogue record.
Data lineage:

Data collated by the Met Office and archived in the Met Office's MIDAS database. Data are extracted from a sub-set of available tables and delivered to BADC approximately on a monthly basis as flat files.

Data Quality:
Data undergo quality checking by the Met Office. State of the data in the quality control process and level of data quality are indicated using version numbers and quality control flagging with the data. See documentation about how to use the quality control flagging and version numbers. There are also some known data from commissioning trials in the data, which are given a src_id of 99999. These should be ignored by the user.
File Format:
Data are ASCII formatted
