Dust RGB captures dust event in the Intermountain West
Tue, 14 April 2015
The MODIS RGB image below captured the dust event in portions of the Intermountain West today, April 14th, as strong winds lifted dust across the drought-stricken region. NWS offices in the region issued high wind warnings and dust storm warnings due to the conditions. Visibilities below one quarter mile in some instances were reported with portions of I-80 closed near Tooele, Utah.
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.

One product SPoRT is providing to the GOES-R Proving Ground is the Geo/Polar hybrid. The resolution of MODIS is similar to the future Advanced Baseline Imager instrument. However, MODIS is a polar orbiting instrument and cannot provide observations in a continuous, looping format like GOES. To address this, SPoRT takes existing GOES data and replaces the portions of the GOES image where MODIS data are available. The result allows the high-resolution MODIS data to be included in an animated loop. The image here from 20 September 2009 shows the 11 micron infrared hybrid product. The MODIS data are to the left of the dashed blue line at 1 km, while the GOES data are to the right at 4 km and shown over the Four Corners region of the southwestern United States.
Ingest and Product Status Pages
Though we're not 24/7, SPoRT strives to provide the most timely and reliable data products to its partners and end users. A system has been developed to monitor the health of our real-time data ingest and availability of LDM and FTP products. Summaries are posted every 10 minutes to the links below.
