Volcanic Ash Product Suite    
     
• Chile's Puyehue-Cordón Caulle Volcano erupted on June 4, 2011, forming a tall ash plume above the Andes Mountains.
   
• The GOES-R Proving Ground provides near real-time volcanic ash retrieval products (using Meteosat SEVIRI data as a proxy for the GOES-R Advanced Baseline Imager) to identify a significant volcanic ash plume emerging over the Atlantic Ocean impacting aviation operations with many cancelled flights.
   
• Similar data was provided by STAR to the London Volcanic Ash Advisory Center (VAAC) during the eruption of Eyjafjallajökull in Iceland in May 2010.

Fog Detection (Future Capability)

The GOES-R fog detection product will significantly improve geostationary satellite fog monitoring capabilities:

• Improved algorithm technology - the GOES-R algorithm provides quantitative information on fog probability, while heritage GOES fog detection products are more qualitative in nature
• Improved sensor technology - the ABI has greatly improved spectral information, spatial resolution, and temporal resolution

Clear Air Turbulence
• Clear Air Turbulence can be a significant aircraft hazard, occasionally causing injuries and long delays.
   
• At the upper-tropospheric boundary between air masses, vertical shearing at the jet stream combined with the ageostrophic convergence of polar, subtropical and stratospheric air produces a region known for its potential for clear air turbulence called a “tropopause fold.”
   
• Water vapor imagery can be used to infer large changes in vertical motion that can herald the presence of turbulence in the atmosphere.
   
• The Tropopause Folding Turbulence Prediction (TFTP) product locates these regions in the atmosphere and identifies the sections most likely to produce turbulent flight conditions for aircraft.
