Run the following commands to regrid 2-meter temperature data several different ways:

Regrid to a pre-defined named NCEP Grid 130:

regrid_data_plane \

$MET_TUTORIAL_DATA/input/sample_fcst/2005080700/wrfprs_ruc13_12.tm00_G212 \

G130 \

$MET_TUTORIAL_DATA/output/regrid_data_plane/tmp_z2_G130.nc \

-field 'name="TMP"; level="Z2";'

The default interpolation method is nearest neighbor. Rerun this command using the mean within a 10x10 interpolation box, which applies a large amount of smoothing:

regrid_data_plane \

$MET_TUTORIAL_DATA/input/sample_fcst/2005080700/wrfprs_ruc13_12.tm00_G212 \

G130 \

$MET_TUTORIAL_DATA/output/regrid_data_plane/tmp_z2_smooth.nc \

-field 'name="TMP"; level="Z2";' \

-method UW_MEAN -width 10

Next, define the output grid using the path to another gridded data file over the Pacific Northwest of the United States using bilinear interpolation:

regrid_data_plane \

$MET_TUTORIAL_DATA/input/sample_fcst/2005080700/wrfprs_ruc13_12.tm00_G212 \

$MET_TUTORIAL_DATA/input/sample_fcst/2009123112/arw-fer-gep1/d01_2009123112_02400.grib \

$MET_TUTORIAL_DATA/output/regrid_data_plane/tmp_z2_bilin.nc \

-field 'name="TMP"; level="Z2";' \

-method BILIN -width 2

Lastly, manually define a LatLon output domain (latlon Nx Ny lat_ll lon_ll delta_lat delta_lon) using the default nearest neighbor interpolation method:

regrid_data_plane \

$MET_TUTORIAL_DATA/input/sample_fcst/2005080700/wrfprs_ruc13_12.tm00_G212 \

'latlon 100 50 25 -100 0.25 0.25' \

$MET_TUTORIAL_DATA/output/regrid_data_plane/tmp_z2_latlon.nc \

-field 'name="TMP"; level="Z2";'
