  Format :
 
  year, month, day,  hour, lat, lon, FRP (mean), FRP (max), confidence level, N

  year, month, day, hour : date and hour (UTC)
  FRP(mean) : Hourly mean FRP of detected wild fire (MW)
  FRP(max) : Hourly max FRP (MW)
  confidence level: mean confidence level (<=5.)
  N: the total number of the detection (1<=N<=6)

  Format :
 
  Daily   : year, month, day,  lat, lon, FRP (mean), FRP (max), N
  Monthly : year, month,  lat, lon, FRP (mean), N


  year, month, day : year, month, day
  FRP(mean): Daily/monthly mean FRP of detected wild fire (MW)
  FRP(max): Daily max FRP (MW)
  N: the total number of the detection


Note 1) FRP denotes the fire radiative power per each grid.


Note 2) Daily/monthly statistics are determined from hourly statistics, its mean confidence level >= 2.5.


Note 3) Total fire radiative energy (FRE) per each grid is estimated by FRP(mean)*N*10min*60sec.
