<div><span style="font-family: calibri, arial, helvetica, sans-serif; font-size: 12pt;">I thought it was a problem because VAR is a real4 variable, so I changed the pressure of the netcdf file from double to float, but it is the same.</span><br>

Hi,
<div class=""><br class="">
</div>
<div class="">I try to read the contents of Netcdf file with nf90mpi_get_var_all, but I get an error code of -40.</div>
<div class="">I want to debug that content, how can I do it? </div>

Even a little thing you know will be of great help to me.<br class="">
