Comparative Analysis between Daily Extreme Temperature and Precipitation Values Derived from Observations and Gridded Datasets in North-Western Romania

摘要: Climate gridded datasets are highly needed and useful in conducting data analysis for research practical purposes. They provide long-term information on various climatic variables large areas worldwide, making them suitable use at any spatial level. It is essential to assess the accuracy of by comparing measured values, especially when they used as input parameters hydro-climatic models. From multitude databases available North-western Romania, we selected three, particularly European Assessment Dataset (E-OBS), Romanian Climatic (ROCADA), Carpathian Region (CARPATCLIM). In this paper, analyse extreme precipitation temperature derived from above-mentioned over a common 50-year period (1961–2010) compare with raw values estimate degree uncertainty each set data. The observation data, recorded two meteorological stations located complex topography region, were compared output datasets, using descriptive statistics mean annual seasonal trend analyses. main findings are: high suitability ROCADA database climate E-OBS analysis.
