The research station is located around 2 km from Ume\u00e5 city center so it is easy to access by train, flight and bus. Established nearly 60 years ago, it operates within a Natura 2000 area and Vindeln's biosphere reserve, and has soils conducive to farming and field research. The facilities support studies in agricultural sciences, animal science, biology, geochemisty, agro-ecology, soil science, and environmental science, offering access to land, technicians, climate and soil data, workshops, and laboratories. The facility includes a dairy barn housing 120 cows, equipped for measuring feed intake, weight, milk production, and greenhouse gas emissions. Two beehives at the station house Nordic bees. The station's urban location in Ume\u00e5 encourages interdisciplinary research, making it a valuable resource for science, teaching, and applied studies. The infrastructure spans 300 hectares, hosting around 40 annual field trials and coordinating trials on three other field stations in northern Sweden. R\u00f6b\u00e4cksdalen is part of two thematic programs within SITES; Spectral and Water. In SITES Spectral data from the fields is collected using masts and drones equipped with spectral cameras. Samples for water chemistry are taken from Degern\u00e4s creek that flows through the fields, which also has continuous discharge measurements.", "descriptionType": "Other"}], "externalSourceInformation": {"externalSourceName": "FieldSites", "externalSourceURI": "https://meta.fieldsites.se/objects/PAdGRZeVbfb8_EvQv6e0xD4j"}, "files": [{"format": "csv", "md5": "PAdGRZeVbfb8_EvQv6e0xD4jM7R7goP6agie287MyQI", "name": "SITES_PHE-ROI-TS_RBD_AGR_PL02_PHE01_20220613-20250505_L3_DAILY.csv", "size": "157541", "sizeMeasureType": "B", "sourceUrl": "https://data.fieldsites.se/objects/PAdGRZeVbfb8_EvQv6e0xD4j"}], "geoLocations": [{"geographicDescription": "R\u00f6b\u00e4cksdalen Research Area, Mast 4m Phenocam 02", "point": {"latitude": 63.809992, "longitude": 20.238822}}, {"boundingPolygon": [{"inPolygonPoint": {"latitude": 63.788297, "longitude": 20.236084}, "points": [{"latitude": 63.788297, "longitude": 20.236084}, {"latitude": 63.78846, "longitude": 20.227268}, {"latitude": 63.794388, "longitude": 20.221015}, {"latitude": 63.799363, "longitude": 20.224163}, {"latitude": 63.804172, "longitude": 20.221038}, {"latitude": 63.806218, "longitude": 20.21625}, {"latitude": 63.808838, "longitude": 20.218288}, {"latitude": 63.81159, "longitude": 20.213524}, {"latitude": 63.8138, "longitude": 20.209457}, {"latitude": 63.81241, "longitude": 20.203547}, {"latitude": 63.813178, "longitude": 20.202277}, {"latitude": 63.811114, "longitude": 20.197328}, {"latitude": 63.811297, "longitude": 20.193818}, {"latitude": 63.811885, "longitude": 20.192956}, {"latitude": 63.812016, "longitude": 20.192961}, {"latitude": 63.813575, "longitude": 20.193689}, {"latitude": 63.815176, "longitude": 20.197625}, {"latitude": 63.814316, "longitude": 20.202224}, {"latitude": 63.815692, "longitude": 20.206805}, {"latitude": 63.813019, "longitude": 20.212836}, {"latitude": 63.816724, "longitude": 20.225143}, {"latitude": 63.816387, "longitude": 20.229766}, {"latitude": 63.814184, "longitude": 20.233638}, {"latitude": 63.81407, "longitude": 20.238261}, {"latitude": 63.813094, "longitude": 20.241935}, {"latitude": 63.812081, "longitude": 20.245676}, {"latitude": 63.812003, "longitude": 20.248568}, {"latitude": 63.811959, "longitude": 20.248696}, {"latitude": 63.808588, "longitude": 20.248211}, {"latitude": 63.806739, "longitude": 20.249543}, {"latitude": 63.805077, "longitude": 20.251088}, {"latitude": 63.804018, "longitude": 20.252451}, {"latitude": 63.799187, "longitude": 20.239591}, {"latitude": 63.789596, "longitude": 20.255329}, {"latitude": 63.788552, "longitude": 20.244313}, {"latitude": 63.788297, "longitude": 20.236084}]}], "geographicDescription": "R\u00f6b\u00e4cksdalen Research Area"}], "keywords": [{"keywordLabel": "Calibration/Validation"}, {"keywordLabel": "Reflectance"}, {"keywordLabel": "Ecosystem functions"}, {"keywordLabel": "Plant Phenology"}, {"keywordLabel": "Vegetation Index"}], "licenses": [{"licenseCode": "SITES CCBY4 Data Licence", "licenseURI": "https://meta.fieldsites.se/ontologies/sites/sitesLicence"}], "projects": [{"projectID": "https://meta.fieldsites.se/resources/projects/spectral", "projectName": "SITES Spectral"}, {"projectID": "https://meta.fieldsites.se/", "projectName": "SITES external record - eLTER Community"}], "publicationDate": "2022-06-13", "relatedIdentifiers": [{"relatedID": "https://meta.fieldsites.se/objects/4dAGtm0Xa72aoxCE0egAlerX", "relatedIDType": "URL", "relatedResourceType": "Dataset", "relationType": "IsNewVersionOf"}], "responsibleOrganizations": [{"organizationName": "SITES Spectral"}, {"organizationName": "Swedish University of Agricultural Sciences"}], "siteReferences": [{"siteID": "7e2e2f68-989c-4e0a-8443-315ea48aac7f", "siteName": "R\u00f6b\u00e4cksdalen Field Research Station - Sweden"}], "temporalCoverages": [{"endDate": "2025-05-05", "startDate": "2022-06-13"}, {"endDate": "2025-05-05", "startDate": "2022-06-12"}], "titles": [{"titleText": "Phenocam - Region Of Interest (ROI) Time Series from R\u00f6b\u00e4cksdalen Research Area, Mast 4m Phenocam 02"}]}, "pids": {"doi": {"identifier": "11676.1/PAdGRZeVbfb8_EvQv6e0xD4j", "provider": "doi.org"}}}
