SNACS Atmospheric Model: source code and configuration files

Project:

Summary

This dataset archives the SNACS Polar MM5 atmospheric model code and settings for the 50km simulations. If you uncompress and then untar the file, you'll have a directory called MM5 which will contain all of the source code and four configuration files.

Data generated by the model includes:
date (yyyy-mm-dd in *_avg.txt file and yyyy-mm-dd_hh in *_3h.txt file) (UTC)
psfc - surface pressure (mb)
slp - sea level pressure (mb)
tg - ground temperature (K)
t2m - 2m air temperature (K)
q2m - 2m water vapor mixing ratio (kg/kg)
ws10 - 10m wind speed (m/s)
wd - 10m wind direction (deg)
ust - friction velocity, u* (m/s)
lhf - latent heat flux (W/m^2)
shf - sensible heat flux (W/m^2)
grnf - ground heat flux (W/m^2)
swd - downwelling shortwave radiation at surface (W/m^2)
swu - upwelling shortwave radiation at surface (W/m^2)
alb - albedo (fraction)
lwd - downwelling longwave radiation at surface (W/m^2)
lwu - upwelling longwave radiation at surface (W/m^2)
p3h - accumulated precipitation (24h in *_avg.txt file and 3h in *_3h.txt file) (cm)
swe - snow water equivalent (mm)
cld_frac - cloud fraction (fraction)
