[ncl-talk] Problem with Time dimension after saving to netcdf file in NCL

[Lyndz]

Dear NCL-experts,

I trying to run my script (attached in this email). There are two issues
that I would like to address and ask for help.

*[1] The script runs but the output time dimension is incorrect when only
one-time step satisfies the conditions. For cases with multiple time steps
satisfying the conditions, the output is ok. Notice the time is 0 from the
ncdump below. Any ideas how to solve this issue?*

Here's the ncdump of the output netcdf file when only one time-step
satisfies the coditions:
dimensions:

time = UNLIMITED ; // (0 currently)
latitude = 280 ;
longitude = 360 ;
variables:
float rain(latitude, longitude) ;
rain:time = 116. ;
rain:level_description = "Earth surface" ;
rain:missing_value = -99.9f ;
rain:_FillValue = -99.9f ;
rain:units = "mm/day" ;
rain:long_name = "daily precipitation analysis interpolated onto 0.25deg
grids [mm/day]" ;
double latitude(latitude) ;
latitude:axis = "Y" ;
latitude:units = "degrees_north" ;
latitude:long_name = "Latitude" ;
latitude:standard_name = "latitude" ;
double longitude(longitude) ;
longitude:axis = "X" ;
longitude:units = "degrees_east" ;
longitude:long_name = "Longitude" ;
longitude:standard_name = "longitude" ;

// global attributes:
:creation_date = "Thu Aug 29 18:28:59 JST 2019" ;
:Conventions = "None" ;
:source_file = "Daily Aphrodite Rainfall" ;
:title = "rain_stretch equal rain_threshold=0" ;
}

*[2] One part of the script save the dates into a text file. Is there a way
to save the output file as YYYY-MM-DD separated by a dash (-) instead of
YYYYMMDD?*

I'll appreciate any help about these.

Sincerely,

Lyndz
