Spring High Terrain New Mexico Snow Event
Mon, 20 Mar 2015
An upper level closed low near Baja and a backdoor front combined to bring considerable precipitation to New Mexico during the day and overnight period of March 19, 2015. Ample moisture surged northward over New Mexico ahead of the closed low, and precipitable water as measured by the soundings at Albuquerque, NM and El Paso, TX tied for the fourth highest value for March since 1950 (at both locations).

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.

The MODIS instrument has several methods for detecting snow cover. The first and most obvious is the Natural Color Composite on the left. However, with the naked eye it can be difficult to differentiate between snow cover and cloud cover. An alternate method is the Snow/Ice Composite, at middle. Compare its results to the EOS Snow Map, at right. Each produces a more accurate and readable picture of the extent of snow cover on the ground. (January 29, 2004, 1620 UTC)
