Changelog

All notable changes to Grond are documented in this file.

The format is based on Keep a Changelog.

Unreleased

Added

  • Scenario:
    • add option to rebuild the scenario
    • add separate source radius
    • add option to use user stations
  • Possibility to fit travel times with picks.

Fixed

  • Various minor bug fixes and improved compatibility.

[1.5.1] 2020-10-26

Fixed

  • Always request that traces should be demeaned before restitution (default has changed from Pyrocko v2020.10.08 to v2020.10.26).

[1.5.0] 2020-10-09

Added

  • Added optional keyword for Parameters, defaults to optional=True.
  • RectangularSource now has a velocity parameter.
  • Possibility to select different GF stores for different sensor depth intervals in a single target group with StationDepthStoreIDSelector.
  • Export complete modelling results and fit characteristics with grond harvest --export-fits.

Fixed

  • Corrected handling of band codes in grondown script in the examples: In the FDSN query arguments for channel the band codes were mistakenly inserted as instrument code (?H?,?B?,?S? instead of H??,B??,S??).

[1.4.0] 2020-08-25

Added

  • Possibility to filter runs in report open dialog.
  • grond go utilises --threads arguments for various tasks.
  • InSAR plots improved, now plotting 'best' and 'mean' // Improvements
  • In grond export, it is now possible to suppress exporting events with combined location uncertainty below a given threshold.
  • Support offset coordinates in station and event inputs.
  • lockfile .running in rundir during inverion. Fixes timeout for monitor.
  • Support develop mode installation.
  • Satellite Plots: added draped surface displacements onto topography.
  • Satellite Plots: added more control through PlotConfig.
  • Satellite Plots: added cyclic radians plots.
  • Option to switch between showing filtered or processed waveforms in grond forward.

Fixed

  • Fix search in HTML report.
  • Fix could not attach to grond environment.
  • Fixes various plotting issues.
  • Improvements in documentation, examples and defaults.
  • Improvents to error and log messages.
  • satellite.plot degree axis offset and close-up scaling for point sources.
  • Improved event/pick association.

[1.3.2] 2019-07-03

Added

  • Can now run target balancing with a fixed magnitude (reference event) for automatic removal of stations providing unreasonably large misfits (use_reference_magnitude and cutoff in TargetBalancingAnalyserConfig).
  • Add possibility to export only results from runs matching given criteria. At the moment, it is possible to select by rundir tag (grond export --selection).

Fixed

  • Corrected time window calculation in NoiseAnalyser
  • Plots not using harvest subset.

[1.3.1] 2019-06-08

Added

  • Allow controlling number of threads in grond report with --threads

Changed

  • Default number of threads used in grond go and grond report is now 1. Setting both together, --parallel and --threads, to values higher than 1 may currently cause hangs.
  • Improved control on threading utilization.

Fixed

  • Repaired grond report and grond plot location_mt which were broken in v1.3.0.

[1.3.0] 2019-06-04

Added

  • Added Covariance weighting from SatelliteTarget and GNSSTarget.
  • Added new Volume source (VLVD).
  • Added SVG as grond plot export format.

Changed

  • Consistent utilisation of ModelHistory for plots and results.
  • MTLocationPlot supports Gamma scaling (misfit^gamma).
  • SatelliteTarget speeds up bootstrapping by multi-threading.
  • Envronment can be initialised from ProblemConfig.
  • Improved: grondown downloading seismic wave forms.

[1.2.0] 2019-02-19

Added

  • Waveform targets: switch to change to acceleration / velocity fitting.
  • Waveform targets: include / exclude stations by pattern on target-group level.
  • Option to export list of stations used in one or more setups (grond check --save-stations-used=<filename>).
  • Can now handle GNSS stations lacking complete set of component orientations.
  • Noise analyser: added possibility to except stations with high S/N ratio from removal due to high pre-event noise.
  • Improved unit tests.
  • Report archive generation can now be skipped via command line flag or report configuration setting.
  • CMT problem: can now switch between different source time functions.
  • Added workaround switch for "cannot project traces with displaced sampling" issues.

Changed

  • Transparent event loading and checking.
  • Noise analyser: target groups are now handled independently. Each group now uses its own threshold in weeding mode.
  • Improved error handling (grond check, instrument responses,
  • Only exclude waveform targets when distance_min constraint is given in problem_config.
  • Improved method chapter in documentation.

Fixed

  • Waveform fit plots: fix crashes while plotting results from joint inversions.
  • Satellite fit plots: fix bug in source outline drawing
  • Waveform targets: fixed handling of channel epochs from StationXML for channel orientations.
  • Station plots: fixed problems with empty target groups.
  • No more MPL warnings 'too many open figures' when creating sequence plots; the plots are now created one by one.
  • Report: fix dsiplay issue with inaccessible elements in left navigation.
  • Fixed crash when starting_point setting in highscore optimiser is set to mean.

[1.1.1] 2019-02-05

Fixed

  • Bug in volume point source plot causing crashes.

[1.1.0] 2019-01-22

[1.0.0] 2019-01-07

Added

  • Cluster analysis on result ensemble with grond cluster.
  • Plotting of cluster analysis results in jointpar, mt_decompostion, and mt_fuzzy plots.
  • User can now add self-defined labels to a run dir (grond tag). The labels are shown in the report list.
  • The optimiser's acceptance and choice history is now dumped and plotted.
  • Added station distribution plot for seismic and GNSS stations.
  • Installation instructions for Anaconda and pip.

Changed

  • Plot location_mt improved.
  • ProblemConfig: added nthreads argument.
  • Plot contributions: show cumulative contributions for targets providing multiple misfits.
