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/29d0ad65-2274-45d5-9f64-b600f9faf983). 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/f2y86-kdx28"}, "files": [{"format": "csv", "md5": "8d56e9da785507aec3838eef5cb77d8c", "name": "it-sr2_gpp_error_estimates_2020-2023.csv", "size": "235", "sizeMeasureType": "B", "sourceUrl": "https://hdl.handle.net/11304/5e4a3f8b-70ab-4d20-8679-f9c7e21e19b4"}, {"format": "zip", "md5": "a7c0f17013a959659e237c03d7b92c76", "name": "it-sr2_netcdfs.zip", "size": "169030142", "sizeMeasureType": "B", "sourceUrl": "https://hdl.handle.net/11304/9c7488b0-dc17-41b6-a36e-8ea6f31fa469"}, {"format": "pdf", "md5": "32f4ce95b84091cbf5b817ec300cdce9", "name": "AGAME_data_product_description_V20260112.pdf", "size": "1008584", "sizeMeasureType": "B", "sourceUrl": "https://hdl.handle.net/11304/6e7785df-e558-4158-9a7d-1d64a81d6e8b"}, {"format": "zip", "md5": "af5918132c6744823b2ae0ba33535edc", "name": "it-sr2_geotiffs.zip", "size": "7389725", "sizeMeasureType": "B", "sourceUrl": "https://hdl.handle.net/11304/96ca9a51-4002-4153-b59a-ae0f1a6bc078"}], "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/3ct04-61g11", "relatedIDType": "URL", "relatedResourceType": "Dataset", "relationType": "IsNewVersionOf"}], "siteReferences": [{"siteID": "29d0ad65-2274-45d5-9f64-b600f9faf983", "siteName": "San Rossore 2 - Italy"}], "titles": [{"titleLanguage": "", "titleText": "San Rossore - Gross Primary Production (2020-2023)"}]}, "pids": {"doi": {"identifier": "10.23728/b2share.f2y86-kdx28", "provider": "datacite"}}}
