1.0 Release Notes
Integrated Data Viewer
Version 6.1u2

The items below reflect changes since the 6.0 release.

1.0 System Changes

1.1. OpenJDK Java Version

Due to the end of Oracle Java free release updates, the IDV project has officially moved from Oracle JDK to OpenJDK packages that receives support via the community. The AdoptOpenJDK provides prebuilt binaries from OpenJDK class libraries. All AdoptOpenJDK binaries and scripts are open source licensed and available for free. The version of the AdoptOpenJDK distributed with the IDV is 1.8.0_282. See the adoptOpenJDK Library for a more details information.

1.2. Latest netCDF-Java Version

The version of the netCDF-Java library currently distributed with the IDV is the 5.5.3. See the netCDF-Java Library for a more details information.

1.3. IDV Appearance Mode

In macOS and Linux users can choose to adopt a light, dark, or IDV regular appearance. The dark appearance, known as Dark Mode, implements an interface style that many apps already adopt. Users can edit the user preference and can choose their interface appearance mode based on ambient lighting conditions.

2.0 Display Changes

2.1. ProbSevere Statistical Model Display

The IDV has developed a new data source type to create a time series display of the ProbSevere Statistical models output that provide probabilistic guidance to forecasters on the likelihood of severe weather occurrence for convection in the near term. Algorithms of ProbSevere incorporate multiple datasets from satellite, radar, total lightning, and NWP into easy-to interpret products. With a direct connection to the NCEP ProbSevere web page to retrieve data of the last 24 hours and the time matching feature of the IDV, it is very easy to integrate ProbSevere model data with other data source types and to assist forecasters in severe weather situations.

2.2. ADT Integration and Development

The Advanced Dvorak Technique (ADT) utilizes longwave-infrared, temperature measurements from geostationary satellites to estimate tropical cyclone (TC) intensity. The Dvorak Technique continues to be the standard method for estimating TC intensity. The ADT is still experimental, and we are keep working on the integration and enhancement of the ADT functionalities for the IDV community.

2.3. Text Html Display

New enhanced Text/Html display avaiable under Displays > Special for displaying straight text or HTML, the display can be added to the view window legend panel for descriptive text about the display.

2.4. Image Capture Quality

When doing the image capture we replaced the original screen capture APIs with Java Canvas3D “OffScreenRendering” to improve the image quality. Keep Java Robot screen capture APIs only when the IDV legend and Full window is needed. Replaced JPEG with PNG as the base image format for the animated movie.

3.0 Jython Changes

3.1. WRF NetCDF Formulas

The original WRF netCDF output is in sigma coordinate. The current grid diagnostic formulas are mostly designed for the isobaric surface parameters. The newly added WRF derived formulas provide functions to directly create the derived parameters such as: Equivalent potential temperature, relative humidity, Saturated Equivalent potential temperature, dewpoint, and others.

4.0 Bug Fixes/Known Problems

4.1. Bug Fixes

We fixed a bug associated with the excessive data loading in this release. Another bug fixed is to handle the redirect of the http urls.

4.2. Known Problems

For a list of outstanding known problems, see the Known Problems page.
