Metadata: An infilled globally complete version of the Dynamically Consistent ENsemble of Temperature at the Earth surface dataset (DCENT): DCENT-I (1850-present)
Abstract:
A globally complete, 200-member ensemble of monthly surface temperature (SST) and land surface air temperature (LSAT) anomalies at 5°x5° resolution, spanning the period from 1850 to present. It is derived from version 2.0 of the unfilled Dynamically Consistent ENsemble of Temperature at the Earth surface (DCENT) dataset and represents 2-metre air temperature over land and sea surface temperature across the marine domain. In addition to the ensemble realisations, summary statistics including the ensemble mean, standard deviation, and the 5th and 95th percentiles, are provided. All temperature values are expressed as anomalies relative to the 1982-2014 climatology, which is also supplied to enable reconstruction of monthly absolute temperatures. A diagnostics file is provided, which contains the land and sea weights and masks, as well as a which quantifies the local kriging variance as a proportion of the prior variance to indicate data reliability. The files contain SST and LSAT separately and combined in the tas variable. DCENT-I combines DCENT’s state-of-the-art bias/homogenisation corrections with a spatially adaptive interpolation method to produce globally complete monthly temperature fields with estimates of uncertainty. The dataset was generated using GloMarGridding v1.0.0-rc.2 (https://github.com/NOCSurfaceProcesses/GloMarGridding) by scientists at the University of Southampton, National Oceanography Centre (NOC), Woods Hole Oceanographic Institution and Harvard University. NOC was supported by the NERC-funded National Capability Programme ‘Atlantic Climate and Environment Strategic Science’ (AtlantiS), grant reference NE/Y005589/1.

| Other details | ||
| Internal code | Internally assigned metadata identifier | 6701 |
| Title | The title is used to provide a brief and precise description of the dataset such as 'Date', 'Originating organisation/programme', 'Location' and 'Type of survey'. All acronyms and abbreviations should be reproduced in full. | An infilled globally complete version of the Dynamically Consistent ENsemble of Temperature at the Earth surface dataset (DCENT): DCENT-I (1850-present) |
| Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | British Oceanographic Data Centre record 1048_DCENT-I_2025 |
| File Identifier | The File Identifier is a code, preferably a GUID, that is globally unique and remains with the same metadata record even if the record is edited or transferred between portals or tools. | 3fc3609677db5ac18a0fc34d2acde422 |
| Resource Identifier | This is the code assigned by the data owner. | EDMED7486 |
| Resource type | The resource type will likely be a dataset but could also be a series (collection of datasets with a common specification) or a service. | dataset |
| Start date | This describes the date the resource starts. This may only be the year if month and day are not known | 1850-01-01 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2024-12-31 |
| Spatial resolution | This describes the spatial resolution of the dataset or the spatial limitations of the service. | inapplicable |
| Frequency of updates | This describes the frequency with which the resource is modified or updated i.e. a monitoring programme that samples once per year has a frequency that is described as 'annually'. | asNeeded |

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | This dataset contains an infilled globally complete version of the Dynamically Consistent ENsemble of Temperature at the Earth surface dataset (DCENT-I) consisting of monthly surface temperature (SST) and land surface air temperature (LSAT) anomalies at 5° x 5° resolution, spanning the period from 1850 to 2025. The outputs were generated under the AtlantiS (NE/Y005589/1) project. The data files are archived at CEDA in the format provided by the originator's and no QC was done by BODC. The data are available via a DOI. |
