[ncl-talk] A missing plot

[Barry Lynn]

HI:

Thank you, one can see the problem below.

Here is the print summary when I don't interpolate to the GEFS grid.  When
compared to when I pass through hilowres (below), you can see that the
lat_0, lon_0 are different.  It doesn't map in the first case because lon_0
is outside my mapping area. .

Variable: fgen_gefs

Type: float

Total Size: 15620 bytes

            3905 values

Number of Dimensions: 2

Dimensions and sizes: [lat_0 | 55] x [lon_0 | 71]

Coordinates:

            lat_0: [52..25]

            lon_0: [90..125]

Number Of Attributes: 3

  _FillValue : 0

  units : K/100 km/3 hr

  short_name : Petterssen Frontogenesis


Here is the printVarSummary when I interpolate first using hi2lowres


Variable: fgen_gefs

Type: float

Total Size: 15620 bytes

            3905 values

Number of Dimensions: 2

Dimensions and sizes: [lat_0 | 55] x [lon_0 | 71]

Coordinates:

            lat_0: [25..52]

            lon_0: [-90..-55]

Number Of Attributes: 3

  _FillValue : 0

  units : K/100 km/3 hr

  short_name : Petterssen Frontogenesis
