WVModelOutputGroupAlongTrack

Represent WaveVortexModel output for satellite along-track sampling.

Declaration

classdef WVModelOutputGroupAlongTrack < WVModelOutputGroup

Overview

WVModelOutputGroupAlongTrack manages the time sampling and NetCDF output for a single satellite altimetry mission using an AlongTrackSimulator. The group precomputes mission pass-overs through the model domain and, when the model reaches a pass-over time, writes the full along-track sample sequence for that pass-over into the corresponding NetCDF group.

Typical usage:

• Create a WVModel NetCDF output file and initialize an AlongTrackSimulator.
• Construct one WVModelOutputGroupAlongTrack per mission and attach it to the output file.

The following code adds output groups for all current satellites

  outputFile = model.createNetCDFFileForModelOutput('ModelOutput.nc',outputInterval=86400);
  ats = AlongTrackSimulator();
  currentMissions = ats.currentMissions;
  for iMission = 1:length(currentMissions)
      outputFile.addOutputGroup(WVModelOutputGroupAlongTrack(model,currentMissions(iMission),ats));
  end

Major responsibilities:

• Store mission metadata and repeat-cycle information.
• Determine pass-over output times for a model integration window.
• Write the complete along-track time series for each pass-over into NetCDF.
• Provide class annotation metadata for property introspection.
