1 The RASM Climate Diagnostics provides time-step averaging output for surface
2 meteorology (PSFC, TSK, PMSL, T2, TH2, Q2, U10, V10), fluxes at the surface
3 (HFX, LH, SWDNB, GLW, LWUPB, SWUPB), and fluxes at the TOA (SWUPT, SWDNT, LWUPT,
4 LWDNT). The averaging can be set by the user with some interval of seconds,
5 minutes, hours, days, or month. The average output file is set to use auxhist5.
7 Additionally, diurnal averaging is provided which creates monthly averages for
8 three hour periods of time during the day (00-03, 03-06, etc.). The diurnal
9 average output is set to use auxhist6. This diurnal averaging output is only
10 created in monthly files (the simulation has to be longer than a month to see
13 The intended application for the RASM Diagnostics is for regional climate
14 simulations and the elimination of the need to produce the high-volume and I/O
15 intenstive instantaneous WRF history files for long duration simulations.

31 frames_per_auxhist5 = 1,
33 -a time interval must be set
34 -only one of the time intervals can be set (cominbations do not work)
36 -settings for RASM diagnostic dirunal output:
37 -flag to turn on the diurnal diagnostic output (1 = on, 0 = off)
39 -use the standard WRF namelist settings for auxhist5 and auxhist6:
40 auxhist6_outname = "wrf_diurnal_d<domain>_<date>.nc",
42 frames_per_auxhist6 = 1,
43 Note: The dirunal output is hard coded for three-hourly intervals
44 (8 values in a day) and output in monthly files.
47 The RASM Climate Diagnostics for WRF was developed and implemented as a part
48 of the Regional Arctic System Model (RASM) project funded by the United States
49 Department of Energy - Regional and Global Climate Modeling Program.
