The Essential Climate Variables (ECV) Inventory houses information on Climate Data Records (CDR) provided mostly by CEOS and CGMS member agencies. The inventory is a structured repository for the characteristics of two types of GCOS ECV CDRs:

  • Climate data records that exist and are accessible, including frequently updated interim CDRs;
  • Climate data records that are planned to be delivered.

EUMETSAT, with the SAF network, has provided a significant portion (~23%) of the CDRs, addressing 19 ECVs across the atmospheric, oceanic, terrestrial and cryosphere domains.

The ECV Inventory is an open resource to explore existing and planned data records from space agency sponsored activities and provides a unique source of information on CDRs available internationally. Access links to the data are provided within the inventory, alongside details of the data’s provenance, integrity and application to climate monitoring.

The release of version 4.1 of the ECV Inventory, complements v4.0 with an ensemble of new and updated entries addressing a selected set of ECVs related to the carbon cycle, in support of the 2022 WGClimate Gap Analysis exercise. The public database holds the characteristics of 1,251 Climate Data Records, addressing 36 GCOS ECVs, spanning the atmospheric, oceanic, and terrestrial domains.

Each registered data record is made available in its latest reviewed version: 4.0 (2021), 3.0 (2020), or 2.0 (2017).
