Hello,
         I am using nccopy to download NCEP reanalysis files from a THREDDS
server using constraint expressions.



*nccopy -4
 
"http://www.esrl.noaa.gov/psd/thredds/dodsC/Datasets/ncep.reanalysis2/pressure/air.2014.nc?air[480:603][2][20:34][26:40]
<http://www.esrl.noaa.gov/psd/thredds/dodsC/Datasets/ncep.reanalysis2/pressure/air.2014.nc?air[480:603][2][20:34][26:40]>”
foo.nc <http://foo.nc>*
However it does not do what I want it to do. When I check the contents of
foo.nc it does not download the latitude, longitude, time and level
information.

The same file downloaded by FTP from ESRL PSD site contains the information
of time, latitude , longitude and and level.

Is there some other option I need to include in the nccopy command so that
the other information is also downloaded ? Do I need to the include the
"-v" option ?


Following is my sample data from using nccopy -

time[0] level[0] lat[0] lon[0] hgt[0]=5758 m
time[0] level[0] lat[0] lon[1] hgt[1]=5715 m
time[0] level[0] lat[0] lon[2] hgt[2]=5679 m
time[0] level[0] lat[0] lon[3] hgt[3]=5658 m
time[0] level[0] lat[0] lon[4] hgt[4]=5651 m
time[0] level[0] lat[0] lon[5] hgt[5]=5656 m
time[0] level[0] lat[0] lon[6] hgt[6]=5666 m
time[0] level[0] lat[0] lon[7] hgt[7]=5675 m
time[0] level[0] lat[0] lon[8] hgt[8]=5680 m
time[0] level[0] lat[0] lon[9] hgt[9]=5680 m
time[0] level[0] lat[0] lon[10] hgt[10]=5678

The same data from FTP -
time[0]=1879032 level[0]=500 lat[0]=40 lon[0]=65 hgt[0]=5758 m
time[0]=1879032 level[0]=500 lat[0]=40 lon[1]=67.5 hgt[1]=5715 m
time[0]=1879032 level[0]=500 lat[0]=40 lon[2]=70 hgt[2]=5679 m
time[0]=1879032 level[0]=500 lat[0]=40 lon[3]=72.5 hgt[3]=5658 m
time[0]=1879032 level[0]=500 lat[0]=40 lon[4]=75 hgt[4]=5651 m
time[0]=1879032 level[0]=500 lat[0]=40 lon[5]=77.5 hgt[5]=5656 m
time[0]=1879032 level[0]=500 lat[0]=40 lon[6]=80 hgt[6]=5666 m
time[0]=1879032 level[0]=500 lat[0]=40 lon[7]=82.5 hgt[7]=5675 m
time[0]=1879032 level[0]=500 lat[0]=40 lon[8]=85 hgt[8]=5680 m
