News and Notes

The IEM Webcam Viewer application has gotten a significant update to hopefully make it more useful to folks. The following changes have been implemented:

• The application has two modes it can run in. A "realtime" mode, which dynamically refreshes all content without user intervention. An "archive" mode, which allows the user to set a time and view all data valid at that time.
• Stable website links are generated for viewing archived content.
• The individual NEXRAD sites in Iowa for plotting were removed for the time being as their archive display logic is a bit tricky. This will get added back someday.
• The application is more efficient now with not making duplicate requests for the same content.
• The display should look better now on large screen sizes.
• The listing of "Webcams" applications on the website's header bar has been rearranged and hopefully better labelled.
• Explicit timestamps and labels are shown below the webcam and RADAR displays. Previously you would have to make assumptions about this or attempt to read the small timestamp in the lower left corner of the webcam image.

Here's an example view of the display in "archive" mode:

In the image, you can see the archived webcam image, archived US NEXRAD Composite imagery, the pointing of each webcam at the time, and any NWS warnings active at that time.

As always, let me know of bugs or suggestions you may have.
