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/a03ef869-aa6f-49cf-8e86-f791ee482ca9). 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/da7ef-zn180"}, "files": [{"format": "pdf", "md5": "32f4ce95b84091cbf5b817ec300cdce9", "name": "AGAME_data_product_description_V20260112.pdf", "size": "1008584", "sizeMeasureType": "B", "sourceUrl": "https://hdl.handle.net/11304/1061541c-646d-4802-a524-2df8a0f89ebb"}, {"format": "zip", "md5": "59297df7fee59419fd1cd35e790c45af", "name": "it-tor_geotiffs.zip", "size": "5405604", "sizeMeasureType": "B", "sourceUrl": "https://hdl.handle.net/11304/b3086b18-6b5a-4d7c-98a2-57b804a9bc70"}, {"format": "csv", "md5": "d5df76da1aceb0c03d4e0a49abac33dd", "name": "it-tor_gpp_error_estimates_2017-2023.csv", "size": "397", "sizeMeasureType": "B", "sourceUrl": "https://hdl.handle.net/11304/27231fa9-b2e7-42d6-90b1-c4799ec5e020"}, {"format": "zip", "md5": "25845730ef8da64b5533e5469685caa1", "name": "it-tor_netcdfs.zip", "size": "225987833", "sizeMeasureType": "B", "sourceUrl": "https://hdl.handle.net/11304/fcae4539-f8b6-4c92-9eb9-426dabb15ace"}], "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/cyn7y-cak63", "relatedIDType": "URL", "relatedResourceType": "Dataset", "relationType": "IsNewVersionOf"}], "siteReferences": [{"siteID": "a03ef869-aa6f-49cf-8e86-f791ee482ca9", "siteName": "Torgnon grassland Tellinod (IT19 Aosta Valley) - Italy"}], "temporalCoverages": [{"endDate": "2024-11-15", "startDate": "2024-11-15"}], "titles": [{"titleLanguage": "", "titleText": "Torgnon - Gross Primary Production (2017-2023)"}]}, "pids": {"doi": {"identifier": "10.23728/b2share.da7ef-zn180", "provider": "datacite"}}}
