[Met_help] ASCII point observation format

I am attempting to create my own ASCII files to use with ascii2nc to
create an observation dataset to use with MET. I am working with two
sets of data. One is surface observations at two locations with the
basic state variables (t2m, td2m, pres, rh, u, v) and also radiation
variables (SW_d, LW_d). The second set of data is upper air
observations. The sample included in the METv1.1 distribution appears
to be for an upper air dataset, so I can likely figure that out in the
future. In the current, I am having some confusion with a few of the
columns in the ASCII Point Observation Format:
column 1 - message_type - How do I know what I am supposed to fill in
for the message_type? Is there a table somewhere with the available
column 7 - I am creating the GRIB files using WPP so I will just enter
the corresponding values for the observations into this column.
column 8 - The MET User's Guide says: "Pressure level in hPa or
accumulation interval in hours for the observation value." What do I
fill in for the T_2m, Td_2m, u_10m, v_10m, or SW_d?
column 9 - "Height in msl of the observation value."
-Similar to column 8, what do I fill in for the T_2m, Td_2m, u_10m,
v_10m, or SW_d?
If you can provide me a sample of an ASCII file for surface observations
it will likely help me.
