Stacey,

According to my colleague and radar specialist, Ryan May, these derived
(the max in a column AKA composite) data are available from NOAA.

We have them here at

http://thredds-test.unidata.ucar.edu/thredds/catalog.xml

Test Datasets > Multi-radar multi-sensor (MRMS) Analysis > MRMS Radar Analysis

Attached, you will find a bundle for these data.

Please let us know if you have any additional questions.

Best,

Unidata IDV Support
