GPP data products are derived using a data-driven approach that integrates Earth observation data with in-situ carbon flux measurements. Specifically, GPP estimations combine Sentinel-2 multispectral imagery with carbon flux data from eddy covariance towers, employing the XGBoost machine learning algorithm for prediction. The resulting GPP maps are generated at a 10-meter spatial resolution and a temporal frequency up to 5 days, covering the period from March 2017 to December 2023. The temporal resolution is contingent upon 50% free-cloud conditions in the area of interest, with lower frequencies occurring during periods of high cloud coverage. The spatial extent of the GPP maps corresponds to the boundaries of long-term observation sites as recorded in the DEIMS-SDR registry (e.g., https://deims.org/459284f2-c7cd-4bb1-96c3-2b38c338ff4a). For sites where the boundary area is smaller than 1 km\u00b2, or if only point coordinates are available in DEIMS-SDR, the maps are constrained to a 1 km x 1 km bounding box.", "descriptionType": "Abstract"}], "externalSourceInformation": {"externalSourceName": "B2Share Eudat", "externalSourceURI": "https://b2share.eudat.eu/api/records/vnfer-ed117"}, "files": [{"format": "zip", "md5": "fc3714035f20d0a8c2ce2b1fda8e932d", "name": "se-nor_geotiffs.zip", "size": "4431594", "sizeMeasureType": "B", "sourceUrl": "https://hdl.handle.net/11304/095aa91d-7032-4572-8e55-b72d2b89eaec"}, {"format": "csv", "md5": "2749049b68042e146c1292e381bdb4aa", "name": "se-nor_gpp_error_estimates_2019-2023.csv", "size": "293", "sizeMeasureType": "B", "sourceUrl": "https://hdl.handle.net/11304/b5dd7c0e-d9d7-493b-b1fa-91fc70965cf1"}, {"format": "zip", "md5": "765d3b46a64cd15218eeac6c5340f19b", "name": "se-nor_netcdfs.zip", "size": "125810551", "sizeMeasureType": "B", "sourceUrl": "https://hdl.handle.net/11304/37a1fbaf-31ce-4727-89d9-7ba683c1aaf5"}, {"format": "pdf", "md5": "32f4ce95b84091cbf5b817ec300cdce9", "name": "AGAME_data_product_description_V20260112.pdf", "size": "1008584", "sizeMeasureType": "B", "sourceUrl": "https://hdl.handle.net/11304/b5e6ed05-5ade-4980-a7ce-eae33d736ec1"}], "keywords": [{"keywordLabel": "AGAME"}], "language": "eng", "licenses": [{"licenseCode": "Creative Commons Attribution 4.0 International", "licenseURI": "https://creativecommons.org/licenses/by/4.0/"}], "projects": [{"projectID": "https://b2share.eudat.eu/communities/LTER", "projectName": "B2SHARE Eudat external record - eLTER Community"}], "publicationDate": "2024-11-15", "relatedIdentifiers": [{"relatedID": "https://b2share.eudat.eu/api/records/xpbmd-by152", "relatedIDType": "URL", "relatedResourceType": "Dataset", "relationType": "IsNewVersionOf"}], "siteReferences": [{"siteID": "459284f2-c7cd-4bb1-96c3-2b38c338ff4a", "siteName": "Norunda - Sweden"}], "temporalCoverages": [{"endDate": "2024-11-15", "startDate": "2024-11-15"}], "titles": [{"titleLanguage": "", "titleText": "Norunda - Gross Primary Production (2019-2023)"}]}, "pids": {"doi": {"identifier": "10.23728/b2share.vnfer-ed117", "provider": "datacite"}}}
