Ashwin,
You must also have to specify time, latitude, longitude and level
coordinated variables associated to the tas variable itself
*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],time[480:603],level[2],lat[20:34],lon[26:40]";
foo.nc*

*P.S: The air variable is a Grid or ARRAY MAP in DAP terminology and it
would be possible to do what you want without specifying coordinated
variables.... but the DAP service implemented by THREDDS is simpler in
constraint expression than others DAP service implementations (i.e. hyrax)

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]”;
foo.nc <http://foo.nc>
*
However it does not do what I want it to do. When I check the contents
of foo.nc <http://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

Ashwin.
