Hi Antonio,<br>
<br>
I think you should have a look at you lines<span><br>
<br>
<tt> xlat = fspan(-90.,90,73)</tt><tt><br>
</tt><tt> xlon = fspan(0.,357.5,144)</tt><br>
<br></span>
you're mixing latitude and longitude and/or use wrong dimension
sizes.<br>
<br>
<font color="#3333ff"><tt> xlat = fspan(-90.,90,144)</tt><tt><br>
</tt><tt> xlon = fspan(0.,357.5,288)</tt></font><br>

Bye,<br>

<div>Hallo NCL,<br>
</div>
Im just wondering why the output of the interpolation filed
are missing in the last latitude (south and north poles:
87.5-90). The input data is bellow:<br>
<br>
netcdf MERRA.U.1979.plev {<br>
dimensions:<br>
time = 365 ;<br>
levels = 42 ;<br>
latitude = 144 ;<br>
longitude = 288 ;<br>
variables:<br>
float U(time, levels, latitude, longitude) ;<br>
U:long_name = "Eastward wind component" ;<br>
U:_FillValue = 1.e+15f ;<br>
U:comments = "Unknown1 variable comment" ;<br>
U:grid_name = "grid-1" ;<br>
U:time_statistic = "average" ;<br>
double time(time) ;<br>
time:standard_name = "time" ;<br>
time:units = "hours since 1979-01-01
12:00:00" ;<br>
time:calendar = "standard" ;<br>
double levels(levels) ;<br>
levels:standard_name = "air_pressure" ;<br>
levels:long_name = "Level" ;<br>
levels:units = "hPa" ;<br>
levels:positive = "down" ;<br>
levels:axis = "Z" ;<br>
double latitude(latitude) ;<br>
latitude:standard_name = "latitude" ;<br>
latitude:long_name = "Latitude" ;<br>
latitude:units = "degrees_north" ;<br>
latitude:axis = "Y" ;<br>
double longitude(longitude) ;<br>
longitude:standard_name = "longitude" ;<br>
longitude:long_name = "Longitude" ;<br>
longitude:units = "degrees_east" ;<br>
longitude:axis = "X" ;<br>
