The CEMS concept is to provide access to a wide range of climate, Earth Observation (EO) and non-EO data alongside various processing and analytical tools. To achieve this, the CEMS facility will collate and store data, in a variety of processed levels and formats, from numerous sources including data providers, academic bodies and commercial organisations. CEMS will also provide access to externally hosted data and enable users to upload their own data onto the system.
CEMS is already able to store more than 5 PetaBytes (5 million GBs) of data, although capacity is expected to increase as the facility develops. Storing data within the CEMS facility alongside high performance computers will enable faster processing and easier data inter-comparisons.
To help users navigate through the data, CEMS offers a data discovery service, which allows users to search the metadata (information describing data) records by particular attributes such as sensor type, acquisition time or location. This will allow the user to quickly find, explore and access the data they want.
The CEMS facility provides access to a wide range of EO datasets, climate model data and related non-EO datasets. Such data is available in a wide range of formats ranging from initial raw data to derived products. To demonstrate the range and types of data that is available through CEMS, example datasets can currently be accessed from these external sources:
