LIS Soil Temperature Observations as More Wintry Precip Moves into the TN Valley
Fri, 20 Feb 2015
Chances for wintry precipitation continue in the Tennessee Valley. This morning and afternoon, another batch of precipitation was moving across areas of the lower to mid Mississippi Valley. Ground reports indicate that much of the precipitation reaching the surface is a mix of snow and sleet in eastern Arkansas and northern Mississippi. Drier air in the lower levels may prevent some of the precipitation from reaching the surface on the northern extent of the precipitation shield. [...]
Evaluation of enhanced high resolution MODIS SSTs and the impact on regional weather forecasts
The NASA Short-term Prediction Research and Transition (SPoRT) Center currently produces a high resolution sea surface temperature (SST) product for use by National Weather Service (NWS) Weather Forecast Offices (WFOs) as an operational diagnostic and also as input for their weather forecast models. This product uses Moderate Resolution Imaging Spectroradiometer (MODIS) data to produce composite SST output with spatial resolution superior to other SST data used to initialize regional weather forecast models. A six month study from February to August 2007 over the marine areas surrounding southern Florida was conducted to compare the use of the MODIS SST composite versus the Real-Time Global SST analysis to initialize the Weather Research and Forecasting (WRF) model.

An observation of the Global Precipitation Measurement satellite's microwave imager showing the 37 GHz Red-Green-Blue composite image in N-AWIPS, available to the National Hurricane Center. This particular image shows Hurricane Gonzala as it approaches Bermuda on 17 October 2014 at 0241 UTC. The composite, which combines the horizontal and vertical polarizations is designed to highlight the main convective regions, which are shown in red.
