Abstract

The global radiation observation data contain hourly and daily radiation amounts, including those no longer being reported. The measurements of global solar irradiation amount, diffuse solar irradiation amount, direct irradiation amount, irradiation balance amount, and global horizontal illumination are recorded by observation stations worldwide and transmitted within SYNOP, HCM, AWSHRLY, MODLERAD, ESAWRADT and DRADR35 messages. The data span from 1947 to present.

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 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.
