I just posted this over at Allisonhouse:
Everyone,
We have just been informed by the National Weather Service that starting in February 2010, and lasting through April, 2010...the National Weather Service will add higher resolution Level3 radar data products, replacing quite a few of the ones you use right now. The legacy products will continue to be sent for 6 months after all of the replacement products have been added, and will be discontinued on December 1, 2010.
What it all means in a nutshell is this:
1. Resolution will increase
2. The number of reflectivity levels will increase to 256 (meaning you will need to have 256 colors in your color palette to display all the intensity levels)
3. The volume of the files will double, on average
4. The Level3 format will change
5. It will be completed by the end of March, 2010...with legacy products ending 12/1/2010.
Allisonhouse will be working closely with its software partners to provide a seamless as possible transition to the newer and better products upon receipt of transmission from the National Weather Service, and we will provide you with more information as it becomes available. Here is the official, techy NOAA announcement.
