ALCF-MODEL(1)

NAME
alcf-model - Extract model data at a point or along a track.

SYNOPSIS
alcf model <type> point: { <lon> <lat> } time: { <start> <end> } [options] [--] <input> <output>
alcf model <type> track: <track> [--] <input> <output>

DESCRIPTION
Arguments following -- are treated as literal strings. Use this delimiter if the input or output file names might otherwise be interpreted as non-strings, e.g. purely numerical file names.

ARGUMENTS

type
    Input data type (see Types below).

input
    Input directory.

output
    Output directory.

lon Point longitude.

lat Point latitutde.

start
    Start time (see Time format below).

end End time (see Time format below).

track
    Track NetCDF file (see Files below).

options
    See Options below.

OPTIONS

-r  Process the input directory recursively.

--track_lon_180
    Expect track longitude between -180 and 180 degrees.

track_override_year: <year>
    Override year in track. Use if comparing observations with a model statistically. Default: none.

TYPES

amps
    Antarctic Mesoscale Prediction System (AMPS).

era5
    ERA5.

icon
    ICON.

jra55
    JRA-55.

merra2
    Modern-Era Retrospective Analysis for Research and Applications, Version 2 (MERRA-2).

nzcsm
    New Zealand Convection Scale Model (NZCSM).

nzesm
    New Zealand Earth System Model (NZESM). [Experimental]

um  UK Met Office Unified Model (UM).

TIME FORMAT
YYYY-MM-DD[THH:MM[:SS]], where YYYY is year, MM is month, DD is day, HH is hour, MM is minute, SS is second. Example: 2000-01-01T00:00:00.

FILES
The track file is a NetCDF file containing 1D variables lon, lat, and time. time is time in format conforming with the NetCDF standard, lon is longitude between 0 and 360 degrees and lat is latitude between -90 and 90 degrees.

EXAMPLES
Extract MERRA-2 model data in M2I3NVASM.5.12.4 at 45 S, 170 E between 1 and 2 January 2020 and store the output in the directory alcf_merra2_model.

    alcf model merra2 point: { -45.0 170.0 } time: { 2020-01-01 2020-01-02 } M2I3NVASM.5.12.4 alcf_merra2_model
