.SH DESCRIPTION
|
|
|
10 |
Interpolate the field "field" of a netCDF file "filename" either onto a pressure surface "Pval" or onto an isentropic surface "Tval", where the level is given in hPa or K, respectively. The output is in the format: min.max, lonmin, latmin, pmin, tmin, lonmax, latmax, pmax, tmax.

.B [1] getmima P20110201_00 T P500
|
|
|
27 |
gives the mimimum and maximum temperature on the 500 hPa surface - the output is: -49.155 -2.606 80.00 -88.00 500 0.0 -143.00 9.00 500 0.0, i.e. the minium temperture is -49.155 deg C at (lon,lat,p,time)=(80, -88, 500, 0) and correspondingly for the maximum temperature.
