1 SPoRT Activities in Support of the GOES-R and JPSS Proving Grounds Andrew L. Molthan, Kevin K. Fuell, and Geoffrey T. Stano NASA Short-term Prediction Research and Transition (SPoRT) Center Marshall Space Flight Center, Huntsville, AL 2 nd NWS Eastern Region Satellite Virtual Workshop February 26, 2013 transitioning unique NASA data and research technologies to operations

2 Overview of SPoRT PG Activities Goals: Develop new products or provide products from collaborators for evaluation. Expose current forecasters to the capabilities of future instruments. Provide feedback to product developers for improvement. Activities: Development of training modules to accompany a variety of products. Targeted evaluation periods featuring site visits, collaboration calls, and surveys (metrics). GOES-R and JPSS PG Partners as of June 14, 2012 transitioning unique NASA data and research technologies to operations

3 Products Overview Use of MODIS and Meteosat-9/SEVIRI capabilities as a proxy for future GOES-R – Multispectral RGB composites that use standard techniques to emphasize key features. Extension of MODIS capabilities to VIIRS where possible – Additional RGB composites in addition to high resolution visible and infrared – New capabilities using the near constant contrast or day-night band. Development of GLM proxies from lightning mapping arrays – Total lightning – Lightning trends and jumps – Relationships to severe weather and lead time Passive microwave composite products and single channel imagery comparable to capabilities of ATMS and NASAs GPM. Demonstrate products within the AWIPS and AWIPS II decision support systems. AWIPS transitioning unique NASA data and research technologies to operations AWIPS II

4 GOES-MODIS-VIIRS Hybrids The primary challenge in using polar orbiting data is temporal resolution. SPoRT has developed a hybrid technique that replaces GOES pixels with MODIS or VIIRS when those data sets are available. This allows for looping and viewing of higher resolution data comparable to GOES-R. MODIS or VIIRS Current GOES IR Hybrid Example transitioning unique NASA data and research technologies to operations

5 Developing RGB Image Techniques EUMETSAT has developed several multispectral RGB composites from the SEVIRI instrument. CIRA also helped to spur interest in these products by providing them to the NHC in Google Earth format. By combining information from multiple channels, resulting images depict: – Air mass characteristics – Cloud microphysics – Separation of fog, low cloud, snow – Dust and other aerosols SPoRT has provided many of these products to end users in AWIPS and N- AWIPS, and moving to AWIPS II as offices complete their transitions to new systems. MODIS Air Mass in AWIPS SEVIRI Air Mass in N-AWIPS transitioning unique NASA data and research technologies to operations

6 MODIS Color Composites The GOES-R ABI will have additional spectral bands, allowing for new false color composites, which assist with image classification and feature detection. SPoRT provides these products in AWIPS for evaluation and testing. Similar products from SEVIRI have been used extensively by the National Centers. Night Microphysics – Fog Detection R: 12-11 μm, G: 11-3.9 μm, B: 11 μm Combines 3 channels of information. transitioning unique NASA data and research technologies to operations

7 Extension to VIIRS Data VIIRS has many capabilities similar to MODIS, with the exception of water vapor bands. SPoRT is providing additional false color composites from VIIRS with minor adjustments to accommodate differences from MODIS. Greater swath coverage and swath edge resolution improves usefulness. MODIS Algorithm Applied to VIIRS Corrected Algorithm to VIIRS Data MODIS VIIRS Improved use of VIIRS RGB products by adjusting to be equivalent in appearance to MODIS transitioning unique NASA data and research technologies to operations

8 Day-Night Band Examples The Day-Night band offers a variety of new opportunities to apply visible-light imagery at night. In this example, combinations of DNB and infrared imagery are performed similar to NRL techniques. transitioning unique NASA data and research technologies to operations

9 Day-Night Band Examples DNB imagery also identifies city lights, changes following disasters, fires, and other features when moonlight is not available. In this example, city lights coverage decreases following Hurricane Isaac. transitioning unique NASA data and research technologies to operations

10 Lightning Demonstrations for GLM The Geostationary Lightning Mapper (GLM) will assist in the detection and prediction of severe weather. As a demo for GLM capabilities, SPoRT provides data from lightning mapping arrays: – North Alabama (NALMA) – Washington, D.C. (DCLMA) – NASA Kennedy Space Center – Other networks are available in CONUS and data are requested These LMAs are used to develop products comparable to future GLM capabilities. land Possible GLM Coverage and 95-05 Lightning Climatology LMA Coverage transitioning unique NASA data and research technologies to operations

11 Utility of Lightning Data In addition to public safety, lightning data provides information related to storm strength and intensification. The lightning jump technique has been used to predict severe weather. Future GLM capabilities may provide similar datasets for jump detection over CONUS. land Updraft Intensifies Vortex Spin-up transitioning unique NASA data and research technologies to operations

12 The SPoRT Pseudo-GLM Product Serves as a placeholder until the official GLM proxy is available. Evaluated as part of the SPC Hazardous Weather Testbed Spring Experiment. Receives CONUS LMA datasets as inputs and downscales to a resolution (8 km) comparable to the GLM capabilities. Future GLM flash rates will help to identify updraft centers within other satellite imagery. transitioning unique NASA data and research technologies to operations

13 New Tools for AWIPS II Applications SPoRT is developing new tools to help forecasters analyze lightning trends as a precursor to an official jump algorithm. The tool allows for semi- automated tracking of individual cells and reports lightning trends, and could also be extended to other products: cloud top cooling rate, etc. Example of an AWIPS II developed by SPoRT/NWS to allow interactive lightning tracking over time. transitioning unique NASA data and research technologies to operations

14 Summary SPoRT participates in the GOES-R and JPSS Proving Grounds, developing products for real- time use that are comparable to future capabilities through demonstrations using MODIS, VIIRS, and SEVIRI. – Emphasizes collaborative partnerships with WFOs, focused on their forecast challenges. Ongoing activities in 2012/2013 will emphasize developing of AWIPS II capabilities and continued, targeted evaluations of products with the end user community. transitioning unique NASA data and research technologies to operations
