CAM namelist question. Outputting fields with 'instantaneous' with setting nhtfrq=0.

[sungduk@uci_edu]

Hi,According to the manual, nhtfrq=0 is for a monthly average. I wonder what happens when the averaging flag for some fields is set at "I", while nhtfrq=0, e.g., empty_htapes = .false.fincl2 = 'TAP:I','QAP:I','Z3:I','DTCOND:A','DTCORE:A','DCQ:A'nhtfrq = 0,0mfilt = 1,1 Are those fileds with ":I" outputted as instatanous at the last time step of each month? Or, I flag is overriden to A flag? Thank you!- Sungduk Yu

Correct.  Fields specified with ':I' on a monthly average file would correspond to the last timestep in the month, which is also the value of the time coordinate when the file is written.  You can mix averaged and instantaneous fields on the same output file.  The averaged fields will contain metadata like :cell_methods = "time: mean"  to indicate that they are averaged.

Hi Sungduk Yu,About setting nhtfrq, I see that in your example you set:
nhtfrq=0,0 I believe you can only set
nhtfrq=0
for the first file series (h0 files but not for h1, h2...)


My expectation is that:
nhtfrq=0,0 
will not work

I thought the same thing as Cecile.  But I tried it and it did work.  I don't remember when we fixed that...

Good to know !

Thank you, both eaton and hannay! Glad it's working. It is very convenient for my application (to close a monthly budget). - Sungduk
