MODIS SST feedback

1. I have utilized the MODIS SST to get a feel for warm eddies and the "cooler" shelf waters. Comparing the observed SST values with PORTS data and buoys shows a discrepancy of 4-7 degrees cooler temperatures in the MODIS SST data than the obs over the Gulf and as much as 10 degrees over [...]

NASA Puts the Right Stuff in the Right Hands
April 22, 2009: Imagine a monster tornado is ripping through a neighboring county and bearing down on yours. If you live in north Alabama, your forecasters are well prepared to tell you when to seek shelter. The National Weather Service there shares a building - the National Space Science and Technology Center - with NASA's Short-term Prediction Research and Transition, or SPoRT, Center. SPoRT puts state-of-the-art NASA satellite data directly into forecasters hands, arming them to recognize weather that threatens your safety.

This image shows the response of the low-level atmospheric flow to changes in sea surface temperature (SST). SST differences (in Kelvin) are shown at left, averaged from May 9-19, 2004. 10-m wind convergence differences, shown at right, averaged during the nighttime hours of 05-11 UTC, indicate that the winds slowed down and converged as they moved from the warm Gulf Stream to the cooler coastal waters (see region circled in yellow). This convergence forced vertical atmospheric motion, which encouraged cloud formation.

New River Gauge near Athens
Fri, 03 Jul 2009 13:14:08
A new river gauge has been installed by the USGS on Swan Creek just south of Athens. The actual gauge appears to be on Strain Rd just west of I-65. To access the data, you can check out our Hydrologic Summary, issued daily around 9AM. Or, if you'd prefer to see data closer to real-time, you [...]
