UCLARIS – urban thermo-hygrometric gridded dataset for Iasi city, Romania

This dataset contains 6 daily gridded climate variables derived from the measurements made during 10 years at 11 screen-level monitoring points for air temperature (T) and relative humidity (RH), distributed over the city of Iași, a medium-sized city in north-eastern Romania. Additionally, T and RH data from 3 air quality monitoring points of the Environmental Protection Agency (EPA) [1], and from the single National Meteorological Administration (NMA) official weather station of Iasi were used. The monitoring points cover the entire urban area of Iasi, sampling the most important local climate zones inside the city. The data were firstly quality controlled and homogenized using the CLIMATOL package [2], and afterwards the spatial distribution was obtained through residual kriging  method with the digital elevation model (DEM) as predictor [3]. 

Climate variables: Maximum air temperature – Tmax; Mean air temperature – Tavg; Minimum air temperature - Tmin; Maximum relative humidity - RHmax; Mean relative humidity - RHavg; Minimum relative humidity – RHmin. 

Spatial extent: from 27.44167 to 27.84167 °E and 47.05833 to 47.25833 °N

Temporal resolution: daily 

Temporal coverage: 2013/01/01 – 2022/12/31
