<div>Hi group:<br>I have downloaded the GSWP2 meteorological forcings from <a href="http://dods.ipsl.jussieu.fr/cgi-bin/nph-dods//gswp/">http://dods.ipsl.jussieu.fr/cgi-bin/nph-dods//gswp/</a>. the variable is resampled by landmask to compress the volume.<br>
So now I cannot find the lat and lon project of the variable, such as, </div>
<div><br>%% ncdump('E:\Tair_era198807.nc') %% Generated 10-Dec-2009 11:42:08<br>nc{'land'} = nclong('land'); %% 15238 elements.<br>nc{'land'}.compress = ncchar(''y x'');<br>
<br>nc{'Tair'} = ncfloat('tstep', 'land'); %% 3779024 elements.<br>nc{'Tair'}.axis = ncchar(''TYX'');<br>nc{'Tair'}.units = ncchar(''K'');<br>nc{'Tair'}.long_name = ncchar(''Near surface air temperature at 2m'');<br>
nc{'Tair'}.associate = ncchar(''time (nav_lat nav_lon)'');<br>nc{'Tair'}.missing_value = ncfloat(1.00000002004088e+020);<br>the variable 'land' span from 2301 to 52312, and is not the index of lat and lon. So my question is what the 'land' values mean? How can I project the Tair to lat and lon grids?<br>
please give me help with your extensive knowledge, at least provide some references. I thank you very much! <br><br>Dec10,2009</div>
