Hi,
According to the law (DEVLET METEOROLOJİ İŞLERİ GENEL MÜDÜRLÜĞÜ TEŞKİLAT VE GÖREVLERİ HAKKINDA KANUN - http://www.mevzuat.adalet.gov.tr/html/727.html) it is possible to operate a private station. But first it is necessary to get a written permission and sending the records recorded from the station to DMİ(State Meteorological Service) at the end of every month. And it is not possible to publish the records without review of DMI .
