Important: We would like to distinguish predictions based on EOP 14 C04 data from those based on new EOP 20 C04 series. Therefore, we ask you to keep the same file names as before for predictions connected with previous C04. For predictions based on new 20 C04 data, please add suffix “_2020” to the file names, e.g. “eoppcc_999_59976_2020” or “eoppcc_999_59976_p_2020”. The content of the files, format and units are not changed.
