It is located in the region of Attica, covering the greater Athens area and the Rafina basin. The region of Attica is characterized as a Mediterranean eco-region, which includes three main land use types: urban, peri-urban and rural. Forests are limited to the mountainous areas of Parnitha, Penteli and Ymittos, which are frequently threatened by devastating wildfires, affecting the local ecosystems, hydrology, soil erosion and climate conditions. The hydrographic network is fragmented, mainly consisting of small coastal basins and streams. The most important water body is river Kifisos, which is a heavily modified water body running through a heavily urbanized environment.","citation":null,"relatedIdentifiers":null,"status":{"label":"Operational","uri":"http:\/\/vocabs.lter-europe.net\/elter_cl\/10772"},"yearEstablished":2005,"yearClosed":null,"relatedSites":null,"siteName":"LTSER Platform Hydrologic Observatory of Athens","shortName":"HOA","siteType":"Platform","protectionLevel":null,"landUse":null,"images":[{"url":"https:\/\/deims.org\/sites\/default\/files\/photos\/HOA1.png","alt":"not defined"},{"url":"https:\/\/deims.org\/sites\/default\/files\/photos\/HOA2.png","alt":"not defined"},{"url":"https:\/\/deims.org\/sites\/default\/files\/photos\/HOA3.png","alt":"not defined"}]},"environmentalCharacteristics":{"airTemperature":{"yearlyAverage":19.1,"monthlyAverage":null,"unit":"\u00b0C","referencePeriod":null},"precipitation":{"yearlyAverage":419.3,"monthlyAverage":null,"unit":"mm","referencePeriod":null},"biogeographicalRegion":"mediterranean","biome":"urban","ecosystemType":[{"label":"Forest","uri":null},{"label":"Mediterranean forests, woodlands, and scrub","uri":null},{"label":"Rivers","uri":null},{"label":"Small rivers","uri":null},{"label":"Urban","uri":null}],"eunisHabitat":[{"label":"Constructed, industrial and other artificial habitats (J)","uri":null},{"label":"Heathland, scrub and tundra (F)","uri":null},{"label":"Woodland, forest and other wooded land (G)","uri":null}],"landforms":null,"geoBonBiome":["Terrestrial"],"geology":null,"hydrology":null,"soils":null,"vegetation":null},"geographic":{"boundaries":"POLYGON ((23.123772786381 38.163394760832, 23.366749855329 38.225436786136, 23.623816457476 38.189449877259, 23.784184335434 38.325175012609, 24.06270958694 38.152945722813, 24.00620194704 37.923068949473, 24.051875894335 37.842732514012, 24.078254903601 37.767177835098, 24.061877324247 37.718720076005, 24.033847295015 37.659707923764, 23.977332411309 37.661200687724, 23.94086734597 37.702802302511, 23.92304966657 37.717143572468, 23.886545943318 37.78118165184, 23.798722801332 37.802610282385, 23.767545610269 37.812803419176, 23.737257749683 37.866236241, 23.651022412672 37.933599449798, 23.607795800154 37.951140627075, 23.542305036441 38.035185043287, 23.421346905038 37.969821281785, 23.232061831163 37.972426266012, 23.117372797118 38.054707302468, 23.187726999008 38.142260111981, 23.123772786381 38.163394760832))","coordinates":"POINT (23.698883 38.04697)","country":["Greece"],"elevation":{"avg":281.4,"min":0,"max":1394,"unit":"msl"},"size":{"value":68700,"unit":"ha"},"relatedLocations":null},"focusDesignScale":{"experiments":{"design":"partly experimentation","scale":"catchment scale"},"observations":{"design":"mainly observation","scale":"entire catchment"},"observedProperties":[{"label":"atmospheric parameter","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/20937"},{"label":"precipitation intensity","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/22204"},{"label":"water depth","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/22310"},{"label":"water level","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/30025"},{"label":"water parameter","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/20945"},{"label":"water quality","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/22312"}]},"infrastructure":{"accessibleAllYear":true,"accessType":"regular car","allPartsAccessible":true,"maintenanceInterval":90,"permanentPowerSupply":true,"operation":{"permanent":true,"notes":null,"siteVisitInterval":15},"notes":null,"collection":[{"label":"Cable based","uri":null},{"label":"Data portal","uri":null},{"label":"GMS\/UMTS","uri":null},{"label":"No lodging possible","uri":null},{"label":"Relational database","uri":null},{"label":"Structured file","uri":null},{"label":"Vehicle 2WD","uri":null}],"data":{"policy":{"url":[{"title":null,"value":"http:\/\/hoa.ntua.gr\/disclaimer\/"}],"rights":["The data provider must be offered co-authorship for publications using this dataset at least within the metadata description","Formal acknowledgement of the dataset providers","The opportunity to collaborate on the project using the dataset","Reprints of articles using the dataset must be provided to the data provider","The dataset provider is given a complete list of all products that make use of the dataset"],"notes":null}}},"relatedResources":null,"projectRelated":{"lter":{"lterSiteClassification":"ltser"}}}}
