ESA Lakes Climate Change Initiative (Lakes_cci): Harmonised lake surface water temperature and lake ice cover gap-filled product derived from Lake_cci CRDP v3.0 , Version 1.0
Abstract
This dataset provides a global Level4 harmonised, gap-filled Lake Surface Water Temperature (LSWT) and Lake Ice Cover (LIC) dataset for 2,000 inland water bodies over the period 2000-2023 as part of the European Space Agency (ESA) Lakes Climate Change Initiative (Lakes_cci) project.
The dataset includes two thematic Lake ECVs: LSWT, derived from optical and thermal satellite observations, supporting analysis of mixing regimes, biogeochemical cycling; and LIC derived from optical satellite observations, describing the ice freeze-up and break-up. Together, these variables provide key indicators of climate variability and change.
This version 1.0 of the harmonised dataset is derived from the ESA CCI Lakes ECV Products Climate Data Research Package (CRDP) v3.0, specifically the LSWT and LIC products. The LSWT and the LIC were gap-filled independently and subsequently harmonised to ensure consistency between the variables. The gap-filling and harmonisation methods are described in three journal articles.
Because the gap-filled LSWT and LIC products are harmonised, they are fully consistent. Therefore, no water temperature is reported for grid cells classified as ice-covered.
The data are reported in two forms: 1) daily global files and 2) per lake time series files. The catalogue includes a CSV file listing all lakes for which the product is available. The lake mask for each lake is provided in all the files.

| Data lineage: |
The dataset was derived from the Level3 LSWT and LIC product of the ESA Lakes Climate Change Initiative (Lakes_cci): Lake products, Version 3.0 as part of the ESA Lakes Climate Change Initiative project. Data was upplied for archiving at the Centre for Environmental Data Analysis (CEDA) as part of the CCI Open Data Portal. |
| Data Quality: |
The L4 gap-filled LSWT+LIC product was validated through manual inspection, comparison with other existing product and comparison with in situ data. Full description of the validation can be found in three journal articles.
