Synopsis

Usage: vg6d_getpoint [options] inputfile outputfile

Description

Grib to sparse points transformation application. It reads grib edition 1 and 2, interpolates data over specified points and exports data into a native v7d file, or into a BUFR/CREX file.

Options

-v STRING, --trans-type=STRING

transformation type, 'inter' for interpolation, 'stencilinter' for interpolation using a stencil at each point, 'polyinter' for statistical processing within given polygons, 'maskinter' for statistical processing within subareas defined by a mask of gridpoints, 'metamorphosis' for keeping the same data but changing the container from grid to sparse points, [default=inter]

-z STRING, --sub-type=STRING

transformation subtype, for 'inter': 'near', 'bilin', for 'stencilinter', 'polyinter', 'maskinter': 'average', 'stddev', 'max', 'min', 'percentile', for 'metamorphosis': 'all', 'coordbb' [default=bilin]

-a REAL, --lon=REAL

longitude of single interpolation point, alternative to --coord-file [default=10.0000000]

-b REAL, --lat=REAL

latitude of single interpolation point, alternative to --coord-file [default=45.0000000]

-c STRING, --coord-file=STRING

file with coordinates of interpolation points, alternative to --lon, --lat; no coordinate information is required for metamorphosis transformation

--coord-format=STRING

format of input file with coordinates, 'native' for vol7d native binary file , 'BUFR' for BUFR file, 'CREX' for CREX file (sparse points), 'shp' for shapefile (sparse points or polygons), 'grib_api' for GRIB file (mask) [default=BUFR]

-a REAL, --ilon=REAL

longitude of the southwestern bounding box corner [default=0.00000000]

-b REAL, --ilat=REAL

latitude of the southwestern bounding box corner [default=30.0000000]

-c REAL, --flon=REAL

longitude of the northeastern bounding box corner [default=30.0000000]

-d REAL, --flat=REAL

latitude of the northeastern bounding box corner [default=60.0000000]

--radius=REAL

radius of stencil in gridpoint units, fractionary values accepted, for 'stencilinter' interpolation

--percentile=REAL

desired percentile, [0.,100.], for '*:percentile' transformations [default=50.0000000]

--maskbounds=REAL[,REAL...]

comma-separated list of boundary values for defining subareas according to values of mask, for 'maskinter' and 'metamorphosis:mask' transformations

-n STRING, --network=STRING

string identifying network for output data [default=generic]

-e, --a-grid

interpolate U/V points of an Arakawa C grid on the corresponding T points of an Arakawa A grid

-f STRING, --output-format=STRING

format of output file, 'native' for vol7d native binary format, 'BUFR' for BUFR with generic template, 'CREX' for CREX format, 'grib_api_csv' for an ASCII csv file with grib_api keys as columns [default=BUFR]

-t STRING, --output-template=STRING

output template for BUFR/CREX, as alias like 'synop', 'metar', 'temp', 'generic' [default=generic]

--output-td=INT

time definition for output vol7d volume, 0 for reference time (more suitable for presenting forecast data) and 1 for verification time (more suitable for comparing forecasts with observations) [default=1]

--output-keys=STRING

keys that have to appear in the output grib_api_csv file, any grib_api key or 'gacsv:xxx'; xxx can be any of: lon, lat, npoint, isodate, value, timerange, p1, p1h, p2, p2h, level1, l1, level2, l2, centre, category, number, discipline, simpledate, simpleverdate [default=]

-i, --noconvert

do not convert values fron grib definition to standard vol7d model data, this option sets vol7d variables to missing so it is not possible to export to some formats, useful with --output-format=grib_api_csv option.

-g, --display

briefly display the data volume imported and exported, warning: this option is incompatible with output on stdout.

-h, --help

show an help message and exit

--version

show version and exit
