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/a5496211-d63f-494b-8da7-64e9abf8898b). 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/ckn1t-0rf07"}, "files": [{"format": "zip", "md5": "ebea984d32922a5fe4be0562a89e6b2f", "name": "fr-mej_geotiffs.zip", "size": "3797280", "sizeMeasureType": "B", "sourceUrl": "https://hdl.handle.net/11304/2e0cc0bd-66a7-4f05-89cd-b9230520e22c"}, {"format": "csv", "md5": "e79f7e407f888e6ec974b7645fbbede7", "name": "fr-mej_gpp_error_estimates_2020-2023.csv", "size": "236", "sizeMeasureType": "B", "sourceUrl": "https://hdl.handle.net/11304/aba36960-4138-45a3-b87c-662a584e8275"}, {"format": "zip", "md5": "bb4eb121175e0c18df75c3f6bc085a73", "name": "fr-mej_netcdfs.zip", "size": "103575540", "sizeMeasureType": "B", "sourceUrl": "https://hdl.handle.net/11304/a20498b1-7b96-4682-9995-7ce938eee7d8"}, {"format": "pdf", "md5": "32f4ce95b84091cbf5b817ec300cdce9", "name": "AGAME_data_product_description_V20260112.pdf", "size": "1008584", "sizeMeasureType": "B", "sourceUrl": "https://hdl.handle.net/11304/736cb6ae-4cd2-4bdd-b224-df7a57189204"}], "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/9hea0-n5j15", "relatedIDType": "URL", "relatedResourceType": "Dataset", "relationType": "IsNewVersionOf"}], "siteReferences": [{"siteID": "a5496211-d63f-494b-8da7-64e9abf8898b", "siteName": "Mejusseaume - France"}], "temporalCoverages": [{"endDate": "2024-11-15", "startDate": "2024-11-15"}], "titles": [{"titleLanguage": "", "titleText": "Mejusseaume - Gross Primary Production (2020-2023)"}]}, "pids": {"doi": {"identifier": "10.23728/b2share.ckn1t-0rf07", "provider": "datacite"}}}
