alcf model
alcf model - extract model data at a point or along a track
Usage:
alcf model <type> point: { <lon> <lat> } time: { <start> <end> } <input>
<output> [options]
alcf model <type> track: <track> <input> <output>
Arguments:
type: input data type (see Types below)input: input directoryoutput: output directorylon: point longitudelat: point latitutdestart: start time (see Time format below)end: end time (see Time format below)track: track NetCDF file (see Track below)options: see Options below
Options:

Types:
amps: Antarctic Mesoscale Prediction System (AMPS)era5: ERA5jra55: JRA-55merra2: 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.
Track:
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.
