Dat file format - 

LE (Latent Heat Flux) in cm H2O / time step
  to convert hourly to W/m2, multiply by 6944.444
  cm/hour = W/m2 * 3600 / (2500*100*100)
NEE (CO2 flux) in gC/m2/time step
  to convert hourly to umol/m2/s, multiply by 23.148
  gC/m2/hr = umol/m2/s * (12*3600)/1e6

Valid file has same number of columns where each column is % of data in 
timestep that is good - range from 0 to 1
