Comparisons of annual meanprecipitation gridded and station data: an example from İstanbul, Turkey
MetadataShow full item record
Gridded precipitation data is valuable for applied climatological research. Gridded dataset are useful because they provide more spatial representation. In comparison to gridded data, station (point) dataset are irregularly distributed throughout space and frequently have periods of missing data. In this study, annual mean precipitation gridded and station dataset are compared using meteorological stations in Istanbul; Florya, Bahçeköy, Kumköy, Kireçburnu, Göztepe, Kandilli, Kartal and Şile between the 1970 – 2007 period. We obtained annual precipitation gridded data from station data with linear interpolation method using Matlab programme tools. The main objective of this study is to demonstrate the differences between the two dataset and to clarify the significance of their different aspects for research in applied climatology.
