Tropical Cyclone Risk Model - TCRM 3.1.9

Minor bugfix update:

track.ncReadTrackData previously returned cftime.DatetimeGregorian objects, which caused newer versions of matplotlib.dates.num2date to fail. This is because we write the tracks with units of 'hours since 1900-01-01 00:00', but matplotlib.dates uses 1970-01-01 as the epoch, and works in units of days (with no way to specify units in the num2date function). This update ensures datetime objects returned by ncReadTrackData are true python datetime objects

Also changing to Github actions for continuous integration testing

Tropical Cyclone Risk Model - TCRM 3.1.7

Bigfix for interpolateTracks.interpolate(), where there was an unhandled case of track length=3, but central pressure values were not assigned. This led to tracks with length=3 having null central pressure values in the interpolated track.

Tropical Cyclone Risk Model - TCRM 3.1.3

More bug fixes:

• A bug where the latitude and longitude were read as doubles, not floats, which rounded the values that led to errors when sampling the mean sea level pressure data
• Location id values were strings, not integers which led to empty queries from the hazard database when plotting return period curves
• Add some verbosity for messages around selection of kernels in the statistical sampling components
• Fix the autocorrelation definition in tests
• Add a __call__ method to DummyStatus in the dummy mpi4py class, allowing the hazard module to complete in serial execution
• AutoPlotHazard.py now reads the number of simulations from the configuration file, rather than hard-coded 10000 simulations

Tropical Cyclone Risk Model - TCRM 3.1.2

A few small issues around data types that were not captured in the initial translation to Python 3. This caused some exceptions with storing long integers in netcdf files, and an issue where wind speed values were not correctly plotted on ARI curves.

Tropical Cyclone Risk Model - TCRM 3.0.1

This update includes a number of minor bug fixes and documentation updates

• Python3 compatability changes

• Updated install.rst to update conda instructions (#75)

• Fix format support (#76)

• Some dependency fixes for Python 3

• new track format

• fix bug when CycloneNumber > 9

• support multiple formats (.csv and .nc)

• Fix scaled reduction in BL model: Previous formulation wasn't reducing the influence of the BL model at the right rate. Includes update to the test data

• WIP: Add scripts to plot gridded statistics. This requires some additional fixes to PlotInterface.maps, which was largely translated to cartopy, but a few lingering functions were still framed in Basemap. There may still be some lurking in here.

Tropical Cyclone Risk Model - TCRM 3.0

TCRM Version 3.0

The main development in this release is the translation to Python 3.x. In part, this was also necessitated by upgrades to our primary computing platform.

We are no longer actively developing v2.1, but critical bug fixes will be considered.

• Upgraded to Python 3.7
• Change to mpi4py for parallelisation
• Removed C-extensions
• Additional environment files to assist with installation
• Development branches have been cleaned up

Tropical Cyclone Risk Model - TCRM 3.0rc3

Updated to remove dependencies on unsupported parallelisation libraries and provide additional conda environment file to make installation easier.

N.B. There may still be some minor issues regarding dependencies. Please let us know if any are missing when running the installation

Tropical Cyclone Risk Model - TCRM v2.0rc1

New features:

• Stores individual events as separate tracks and wind fields;
• Tracks stored in netCDF4 files, using the hierarchical structure and compound variables to improve file management for large simulations;
• Provides a relational database to allow interrogation of simulations (using an SQLite database);
• Updated visualisation of outputs using Seaborn;

Bug fixes:

• Update kernel density estimation methods. Previous version oversmoothed the distribution and used an isotropic bandwidth. Now uses statsmodels Multivariate KDE method for 2-dimensional KDE;
• Numpy 1.10.1 compatibility fix (see commit 0361c7c);
• Wind speed averaging times are as per WMO-TD1555 - default output is 0.2 second wind gust;

Tropical Cyclone Risk Model - Minor fixes for individual simulations

This release fixes two minor errors. One prevented the tcevent.py script executing if the 'akima' module could not be imported. The second stopped PlotInterface.plotTimeseries() from executing, due to a deprecated keyword argument when reading the time series data files.

Tropical Cyclone Risk Model - TCRM version 1.0

This is the first release of the Tropical Cyclone Risk Model, for estimating the wind hazard from tropical cyclones. The model is under active development by Geoscience Australia.

A benchmark event set generated with this version of the model is available through the National Computational Infrastructure Data Collections, as part of the Australian Natural Hazards Data Archive, where the data can be accessed via HTTP, OPENDaP, WMS, NCML, NetCDFSubset services and others.

• Reduce memory overhead when extracting timeseries data from scenario simulations;
• Fix incorrect wind speed calculations arising from spurious pressure rates of change;
