The station, founded in 1988, covers a total area of 1,010 hectares with 900 hectares of productive forest, half of which is made up of spruce forests, one-fourth of conifer mix and one-fourth of pine with deciduous trees. The conventionally managed Asa Experimental Forest is primarily used by researchers to study forest production and management, while the unique Asa high-yield experimental forest is used to explore the various landscape-level impacts of intensive forest management on everything from water quality to recreational value. Aneboda Research Area, with mires and conifer forests, serves as a reference for natural forest development stages. The station also has a comprehensive program for measurements of climate (WMO-standard), stream water chemistry, greenhouse gases (FOMA-flux and a flux tower in the high yield forest) and phenology. Additionally, Lake Feresj\u00f6n provides access to an extensive lake monitoring program and its connected streams.", "descriptionType": "Other"}], "externalSourceInformation": {"externalSourceName": "FieldSites", "externalSourceURI": "https://meta.fieldsites.se/objects/ZO_OKq8gtE28v4DKAInhy1M_"}, "files": [{"format": "zip", "md5": "ZO_OKq8gtE28v4DKAInhy1M_6UhL4iVnSQmx5cVi8pA", "name": "SITES_UAV-MSP_ASA_NYB_20180726-U01-U02_ORTHO_L2.zip", "size": "232700173", "sizeMeasureType": "B", "sourceUrl": "https://data.fieldsites.se/objects/ZO_OKq8gtE28v4DKAInhy1M_"}], "geoLocations": [{"boundingPolygon": [{"inPolygonPoint": {"latitude": 57.152988, "longitude": 14.739254}, "points": [{"latitude": 57.152988, "longitude": 14.739254}, {"latitude": 57.153017, "longitude": 14.740095}, {"latitude": 57.152966, "longitude": 14.740172}, {"latitude": 57.15296, "longitude": 14.740678}, {"latitude": 57.153075, "longitude": 14.741287}, {"latitude": 57.151806, "longitude": 14.741572}, {"latitude": 57.151701, "longitude": 14.743826}, {"latitude": 57.152079, "longitude": 14.745674}, {"latitude": 57.15191, "longitude": 14.74808}, {"latitude": 57.151726, "longitude": 14.749099}, {"latitude": 57.149474, "longitude": 14.750157}, {"latitude": 57.14743, "longitude": 14.749615}, {"latitude": 57.147266, "longitude": 14.743209}, {"latitude": 57.146192, "longitude": 14.741047}, {"latitude": 57.146068, "longitude": 14.74072}, {"latitude": 57.146339, "longitude": 14.739255}, {"latitude": 57.145458, "longitude": 14.737622}, {"latitude": 57.145799, "longitude": 14.736838}, {"latitude": 57.146306, "longitude": 14.736556}, {"latitude": 57.149564, "longitude": 14.733884}, {"latitude": 57.150205, "longitude": 14.732391}, {"latitude": 57.150781, "longitude": 14.732312}, {"latitude": 57.151455, "longitude": 14.733316}, {"latitude": 57.152988, "longitude": 14.739254}]}], "geographicDescription": "Nybygget"}], "keywords": [{"keywordLabel": "Calibration/Validation"}, {"keywordLabel": "Reflectance"}, {"keywordLabel": "Ecosystem functions"}, {"keywordLabel": "Plant Phenology"}, {"keywordLabel": "Digital Elevation / Digital Surface Models"}], "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": "2018-07-26", "relatedIdentifiers": [{"relatedID": "https://meta.fieldsites.se/objects/-lqVEgYcw0adXDP_1eMAFi0a", "relatedIDType": "URL", "relatedResourceType": "Dataset", "relationType": "IsNewVersionOf"}], "responsibleOrganizations": [{"organizationName": "SITES Spectral"}, {"organizationName": "Swedish University of Agricultural Sciences"}], "siteReferences": [{"siteID": "13b28889-ed32-495a-9bb6-a0886099e6d9", "siteName": "Asa Experimental Forest and Research Station - Sweden"}], "temporalCoverages": [{"endDate": "2018-07-26", "startDate": "2018-07-26"}], "titles": [{"titleText": "UAV - Multispectral orthomosaic from Nybygget"}]}, "pids": {"doi": {"identifier": "11676.1/ZO_OKq8gtE28v4DKAInhy1M_", "provider": "doi.org"}}}
