Presumably, the variable "ua1" is on the same grid as the
lat2d/lon2d variables. Ie: for each year/month/level the
mjx=nlat and the mix=mlon. Then
ua1New = onedtond( ndtooned(ua1), (/ntim,nlev,nlat,mlon/))
--- Something like
dimensions:
time = 120 ;
nlon = 360 ;
nlat = 240 ;
lev = 40 ; ; kp
integer time(time) ;
time:long_name = "time"
time:units = "yyyymm"
float lev(lev) ;
lev:long_name = "pressure level"
lev:units = "hPa"
float LAT2D(nlat, nlon)
LAT2D:long_name = "array of latitudes"
LAT2D:units = "degrees_north"
float LON2D(nlat, nlon)
LON2D:long_name = "array of longitudes"
LON2D:units = "degrees_east"
float UA1(time, lev, nlat, nlon)
UA1:long_name = "Whatever UA1 is"
UA1:units = "?"
UA1:_FillValue = 1e+20f
TEMP:missing_value = 1e+20f

You can put lat2d and lon2d into 1D variables. That is not the
problem. By definition, a netCDF *coordinate variable* is
a one dimensional array that contains monotonically
increasing or decreasing values. If you tried to assign
the one dimensional versions of LAT2D and LON2D as
coordinate variables the underlying netCDF software which
NCL uses would reject them because they are not monotonic.
good luck
