Using Blog Posts at the Hazardous Weather Testbed (HWT) to advocate for the GeoXO Sounder

The Hazardous Weather Testbed (HWT) at the Storm Prediction Center offers developers an opportunity to test out products in front of forecasters to gauge their reactions. At the past three HWTs, a modeling system that incorporates Polar Hyperspectral Sounding (PHS) (infrared and microwave) data with Advanced Baseline Imager (ABI) to exploit the excellent spectral resolution of PHS data and the excellent spatio-temporal resolution of the ABI has been shown to NWS forecasters in part to demonstrate to them the benefits of a geostationary hyperspectral sounder as might occur on GeoXO, the next-generation geostationary satellite constellation planned for launch in the mid-2030s. This talk will highlight some of the examples discussed both by forecasters and developers on different blogs, showing how the addition of Polar Hyperspectral data does indeed lead to more accurate forecasts, especially of convective initiation.
