[Met_help] [rt.rap.ucar.edu #80577] History for Enquiry About decimals of Lat/Lon in ascii2nc tool

----------------------------------------------------------------
Initial Request
----------------------------------------------------------------
Dear staff,
I am a student using METv5.2-bugfixed tool to convert my ascii file to nc
file for my research. Recently, I found the tool could only ingest two
decimals of lat/lon. For example, when I ncdump the sample_output.nc, the
hdr_arr could only showed 35.03, -106.62 and no more decimals would show
when I added more decimals on the sample.txt. Is the tool limited to have
two decimals on lat/lon or could you provide any methods to fix this
problem? Thank you so much for looking at this email and I am looking
forward to get your reply.
Best regards,
Teng Fei

Teng,
I see that you're using the ascii2nc tool and are wondering about the
precision available for lat/lon values.
To my knowledge there is no limitation on the precision of the lat/lon
values. You can definitely use more than 2 decimal places! To test
this
out, I ran the following commands using test data that's included in
the
met-5.2 tarball.
> cd met-5.2_bugfix
> head -1 data/sample_obs/ascii/precip24_2010010112.ascii
ADPSFC 1L2 20100101_120000 34.0081 -118.4989 -9999.00 61
24
-9999.00 NA 0.00
# Notice that the lat/lon of (34.0081, -118.4989) use 4 decimal
places
> bin/ascii2nc data/sample_obs/ascii/precip24_2010010112.ascii
precip24_2010010112.nc
> ncdump -v hdr_arr precip24_2010010112.nc | head -50
...
hdr_arr =
34.0081, -118.4989, -9999,
# Notice that the same 4 decimal places of precision do show up in
the
output
Are you seeing behavior that's different from what I'm describing?
Thanks,

I see that you're using the ascii2nc tool and are wondering about the
precision available for lat/lon values.
To my knowledge there is no limitation on the precision of the lat/lon
values. You can definitely use more than 2 decimal places! To test

the

hdr_arr =

# Notice that the same 4 decimal places of precision do show up in
the

Are you seeing behavior that's different from what I'm describing?

Dear John,
I have antoher question is that if I want to modify the lat/lon in
sample_ascii_obs.txt under path of /data/sample_obs/ascii/, the output
seemed like did not work (decimals limit to two). Can you help me
figure it
out? Thank you.

From: Julie Prestopnik

Hi Teng.
John is currently out of the office, but I can try to help you.
Could you please send me the ASCII file that you would like to convert
to
NetCDF? You can post it to our anonymous ftp site following these
instructions:
http://www.dtcenter.org/met/users/support/met_help.php#ftp
Please write back once you've posted it, and I'll go grab it.
Could you please also send me the exact command that you are running?
Thanks!
Julie

Dear Julie,
I used '/bin/ascii2nc myfile.txt output.nc' and it works with
unlimited
decimals included. I have another question that I have a very big data
and
I found the MET tool cannot ingest it because of the range limited, do
I
need to segment it into different smaller data? In addition, what is
the
maximum size/lines of an available data file can be ingested? Thank
you!

Teng

Hi, Julie,
This is the command I used:

Subject: Enquiry About decimals of Lat/Lon in ascii2nc tool
From: John Halley Gotway
Time: Thu Jun 08 10:32:51 2017
Julie,
Changing from tab-separated to space-separated fixes the parsing
problem:
cat 321.txt | sed -r 's/\t/ /g' > 321_space.txt
met-6.0/bin/ascii2nc 321_space.txt 321_space.nc -format met_point

From: Julie Prestopnik

Thank you for sending your file and command. Unfortunately, the MET
code
expects your data to be space delimited instead of tab delimited. If
I
chance your file to have spaces instead of tabs:
cat 321.txt | sed -r 's/\t/ /g' > 321_space.txt
Then, I get a successful run. I have attached the space delimited
file.
We are planning to modify our code so that future releases of MET will
accept tab delimited files as well.
I hope this helps!
Thanks,
Julie
