1.0 Release Notes
Integrated Data Viewer
Version 5.5

The items below reflect changes since the 5.4 release.


1.0 System Changes

1.1. Latest netCDF-Java Version

The version of the netCDF-Java library currently distributed with the IDV is the 4.6.11. This is a bug fix release. See the netCDF-Java Library for a more details information.


2.0 Display Changes

2.1. Isentropic Analysis

For synoptic scale motions, isentropic surfaces are material surfaces. Atmospheric variables tend to be better correlated along an isentropic surface upstream/downstream. In a 3D visualization space, the new 3D isentropic analysis makes it intuitive to diagnose horizontal and vertical motion of the atmosphere, and helps us better understand the dynamic and stability of weather phenomenons.


2.2. Scatter Analysis

The IDV constructs scatterplots to illustrate different types of direction and strength of relationships of different weather parameters, where the values of one variable are along X axis and the values of the second variable are along the Y axis. The new scatter analysis is used to create a scatter plot to study the relationships between two 2D parameters. A Scatter analysis also provides statistical information about the data as a whole, as well as the subset regions of the data.


2.3. GOES-16 GLM Display

The GLM L2 product consists of geo-located and time-stamped events, groups, and flashes, with associated calibrated optical amplitudes (in units of Joules). The IDV has three new data source types: GLM EVENT Data files, GLM GROUP Data files, and GLM FLASH Data file to view these three GLM products.


2.4. Grid 3D Surface Smoothing

IDV extands the all 2D horizontal smoothing types to 3D gridded parameters. The smoothing is now available on 3D displays like isosurfaces of gridded dataset and level2 radar dataset.


2.5. Authentication logic upgraded

IDV advances its authentication logic to handle the password changed and/or input wrong password.


3.0 Jython Changes

3.1. Basic Grid Math

A collection of Utilites from Mapes IDV collection performs a series of basic grid divide, multiply, modulo, and vertical derivative.


3.2. 3D Scalar Field Horizontal Smoothing

A collection of Utilites from Mapes IDV collection applies a series of horizontal smoothing on 3D field.


3.3. Time Mean and Anomaly

A collection of Utilites from Mapes IDV collection calculates a series of daily, monthly, yearly mean and anomaly.


3.4. Publishing to the RAMADDA

The new ISL publish tag will publish a file to RAMADDA server.


4.0 Bug Fixes/Known Problems

4.1. Bug Fixes

We fixed a long time bug associated with the CAPE/CIN calculation 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.
