a question about output frequency set hourly with Qian data?

[dyjbean@gmail_com]

Qian forcing data has two temporal resolutions: three hour and six hour.
how can define the output frequency with one hour which can be verified with measurement.

the hist_nhtfrq can be set -24 which represent daily , if it's set -1, then represents hourly,
but what value the hist_mfilt should be set to respond to hourly frequency?

hist_mfilt specify the number of time samples to write to each history file series (a time sample is the history output from a given timestep).For instance, in your case you have hist_nhtfrq=-1 (hourly)if you set mfilt=24 you will have 24 time samples in your history (1 file per day with hourly data)
if you set mfilt=1 you will have 1 time samples in your histiory (1 file per hour with hourly data)
