This project focuses on rescuing and digitizing historical monthly rainfall data in Istanbul from 1846 to 1917 for the first time. Rainfall records were collected by foreign scientists, engineers, and officials during the last century of the Ottoman Empire. Guidelines on Best Practices for Climate Data Rescue by the World Meteorological Organization were followed for rescuing the weather observations.
