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., d2f5457f-6318-494a-b363-8098356035b7). 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/mwvnf-wca40"}, "files": [{"format": "zip", "md5": "5a7ea50935c158381a2c1746928ea4df", "name": "de-hoh_geotiffs.zip", "size": "8670718", "sizeMeasureType": "B", "sourceUrl": "https://hdl.handle.net/11304/8971259f-2182-4c6a-a97a-0978ab2e5a75"}, {"format": "csv", "md5": "f9047192fabab212d31583bb180c42b6", "name": "de-hoh_gpp_error_estimates_2020-2023.csv", "size": "236", "sizeMeasureType": "B", "sourceUrl": "https://hdl.handle.net/11304/ee9b673f-a1a6-4582-8f59-2d03a2118353"}, {"format": "zip", "md5": "58236fd7453a471019ef3b5daa2931fe", "name": "de-hoh_netcdfs.zip", "size": "265853426", "sizeMeasureType": "B", "sourceUrl": "https://hdl.handle.net/11304/c6f1595e-b4bb-44d0-bab8-20f62a85c989"}, {"format": "pdf", "md5": "32f4ce95b84091cbf5b817ec300cdce9", "name": "AGAME_data_product_description_V20260112.pdf", "size": "1008584", "sizeMeasureType": "B", "sourceUrl": "https://hdl.handle.net/11304/5bcb3fcf-c4b2-4f58-a8f1-43fabe6c2252"}], "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/g81es-q5w43", "relatedIDType": "URL", "relatedResourceType": "Dataset", "relationType": "IsNewVersionOf"}], "siteReferences": [{"siteID": "ddd2e8d2-44db-420e-8fa4-6b4fe1b00c78", "siteName": "TERENO Harz - central german lowland - Hohes Holz - Germany"}], "temporalCoverages": [{"endDate": "2024-11-15", "startDate": "2024-11-15"}], "titles": [{"titleLanguage": "", "titleText": "Hohes Holz - Gross Primary Production (2020-2023)"}]}, "pids": {"doi": {"identifier": "10.23728/b2share.mwvnf-wca40", "provider": "datacite"}}}
