About precipitation data


At the Hungarian Hydrological Forecasting Service based on the meteorological observations received from the Hungarian Meteorological Service, the mean areal precipitation for each sub-basin is determined every morning. After receiving the data, it is interpolated on a grid that takes into account the orographic effects and then the mean areal precipitation values calculated in the morning, based solely on the measurements, are refined based on the resulting grid point values.
Multiple-day precipitation sums are produced by adding up mean areal precipitation values for individual days.
