Due to the large data density and restrictions by the measurement providers, we follow the same pattern likewise Chernobyl data. Therefore, we have gridded the measurements using IDW (Inverse Distance Weighting) interpolation of the original data. Therefore, they are easily and directly accessible and they may be used for scientific studies. The format is LON, LAT, VALUE (Cs134 or Cs137 followed by the unit) and the name of the ascii-files starts with “gridded_” followed by the name as before (e.g. Cs134_dep) and ends with the resolution (e.g. 0.01×0.01) and the year. So far, only years 2011 (decay corrected to 31^st March 2011) and 2012 (decay corrected to 31^st May 2012) measurements have been implemented). The interpolated levels can be seen below, while the data can be directly obtained by clicking on the figures:
