The naming convention for NetCDF data files is as follows:

4801Aspd-a1h_d1.cdf

4801A Traditional data identifier Data Record Identifier. First three digits identify moorings chronologically. Fourth digit identifies data loggers sequentially from top.Capital letter suffix (optional) identifies data subsets.
spd

spd or s (velocities corrected for speed of sound)
v (velocities-averaged or basic time step)
tct (temperature, conductivity, transmission)
p (pressure [averaged or basic time step])
psd (pressure standard deviation)
var (variances and covariances of velocity)
ox (oxygen)
cst (conductivity, salinity, temperature)
t (temperature)
tc (temperature, conductivity)
tcp (temperature, conductivity, pressure)
att or ats (transmission and attenuation)
pct (pressure, conductivity [salinity], transmission)
adc (all ADCP variables)
vm (all VMCM variables)
sc (all SEACAT variables)
mc (all MicroCAT variables)
(none) (all data from this data logger)

Variable
-alh-a (best basic version)
-alh (hour averaged best basic version)
-alp (low-pass filtered best basic version)
-m (merged basic versions)
-mlh (merged then hour averaged) 		File Version
_dl_dl
_d2
etc		(optional) depth identifiers used when a single data logger records the same variables at different depths (requiring separate EPIC "time series" data files)
.nc.dat (ASCII file)
.mat (Matlab file)
.nc (netCDF file) 		File Extension
