Objective of this report is the analysis of rainfall and meteorological data that are gathered from the pilot basins and the description of their processing for the generation of the essential time series. The time series that are derived through processing of real-time raw data from the monitoring network are: (a) point time series of rainfall and other meteorological variables (temperature, relative humidity, wind velocity), and (b) time series of areal rainfall and potential evapotranspiration across all sub-basins of interest. Point rainfall depths from rain gauges are used for the generation of areal time series as well as the analysis of intense storm events. The extraction of areal rainfall across each basin or sub-basin of interest was done through typical techniques of spatial integration (Thiessen polygons), while the potential evapotranspiration data were indirectly estimated, as function of temperature.
