    R[1|2|3]/F[YYYY][MM][DD][HH]S[NNNNNNN][ECC|DEW].CSV

        R[1|2|3]: Receiver number. 
             We used three receivers (R1, R2, and R3) for the special radio soundings.
             All are the same type of Meisei RD08AC system.
	     The receiver R3 was used in all the ozone and water vapor soundings. 
             Depending on the situation, receivers R1 and/or R2 were also used 
             simultaneously as a backup for some soundings.

        [YYYY][MM][DD][HH]: Launch date and time

        [NNNNNNN]: Serial number of radiosonde.

        [ECC|DEW]:

            None: PTU data (taken by RS-11G radiosonde)
            ECC: ECC ozone data
	    DEW: Skydew water vapor data
