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/213a9ea7-0155-408d-8763-0a9fabf4a666). 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/h77ea-z1h74"}, "files": [{"format": "zip", "md5": "b1e5c8c54dd110429ebdac5e11b8ab99", "name": "de-har_netcdfs.zip", "size": "57907395", "sizeMeasureType": "B", "sourceUrl": "https://hdl.handle.net/11304/77fe00f8-7f6c-4b7e-869f-01c3b368edea"}, {"format": "pdf", "md5": "32f4ce95b84091cbf5b817ec300cdce9", "name": "AGAME_data_product_description_V20260112.pdf", "size": "1008584", "sizeMeasureType": "B", "sourceUrl": "https://hdl.handle.net/11304/4e286766-d404-4550-8c62-4cacdd81e3f7"}, {"format": "zip", "md5": "1156835205e7036dc7e930e8c4061b8b", "name": "de-har_geotiffs.zip", "size": "2012758", "sizeMeasureType": "B", "sourceUrl": "https://hdl.handle.net/11304/7bac2f28-b7f0-40a5-921c-18000a09b9b0"}, {"format": "csv", "md5": "8bf92d61ac8a00c0c1501013b511550e", "name": "de-har_gpp_error_estimates_2020-2023.csv", "size": "158", "sizeMeasureType": "B", "sourceUrl": "https://hdl.handle.net/11304/134bc9b3-5bb9-4ae7-b647-4e01bf324eb8"}], "keywords": [{"keywordLabel": "AGAME"}], "language": "eng", "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/8x1e8-dvr85", "relatedIDType": "URL", "relatedResourceType": "Dataset", "relationType": "IsNewVersionOf"}], "siteReferences": [{"siteID": "213a9ea7-0155-408d-8763-0a9fabf4a666", "siteName": "Hartheim - Germany"}], "temporalCoverages": [{"endDate": "2024-11-15", "startDate": "2024-11-15"}], "titles": [{"titleLanguage": "", "titleText": "Hartheim - Gross Primary Production (2020-2023)"}]}, "pids": {"doi": {"identifier": "10.23728/b2share.h77ea-z1h74", "provider": "datacite"}}}
