GeoRing-ProxyVisible Satellite Imagery: Turning Night into Day with Machine Learning
Galina Chirokova, CIRA/CSU
Visible satellite imagery from geostationary satellites is used for a variety of applications, including identification of low cloud motions in and around the center of hurricanes. Since visible imagery relies in reflected sunlight, it’s only available during the day. This project seeks to use a machine learning method to bring in information from both geostationary and polar orbiting satellites to approximate visible imagery during the nighttime, then apply it to operational geostationary imagers around the globe. This will provide forecasters with a 24x7 source for both high and low cloud identification.
New Fused GEO+LEO Multi-Satellite Product: Stereo-Winds from Collocated ABI and VIIRS Datasets
Jaime Daniels, NOAA/NESDIS/STAR
The ability to view the same cloud from two different satellites at different look angles allows an accurate estimation of the cloud height using stereo techniques. The same method can be done with a combination of geostationary and low Earth orbiting satellites. This project aims to implement that methodology in regions where GOES-16, GOES-17, and the VIIRS instrument on NOAA-20 and SNPP overlap. The clouds can then be tracked in time to estimate winds with accurate height assignments, which in turn can be assimilated into numerical weather prediction models, leading to better weather forecasts.

Stephanie Stevenson, NOAA/NWS/NHC
This project involves use of the GOES-16/17 Geostationary Lightning Mapper, with the help of machine learning, to better understand the relationship between lightning and tropical cyclone behavior. If successful, the GLM information may improve the prediction of hurricane strength and intensity, which has the potential to save lives of people in hurricane-prone areas
Determination of Exospheric Neutral Hydrogen Density from GOES-R
Janet Machol, Univ. of Colorado
This project will use data from the Extreme Ultraviolet and X-Ray Irradiance Sensors (EXIS) from GOES-16/17 to determine daily neutral hydrogen (H) density distributions of the terrestrial upper atmosphere. Knowledge of the neutral H density distribution at the bottom edge of the exosphere (the exopause) is needed to set the upper boundary for the empirical MSISE model which provides the neutral temperature and densities in Earth's atmosphere from ground to thermospheric heights. MSISE is the international standard model used to estimate satellite drag for orbit calculations. Improved estimates would greatly help satellite operators and atmospheric modeling communities.

This project will use observations from the GOES-16/17 Advanced Baseline Imager to develop a state-of-the-art ice optical property model. This model will then be incorporated into the Community Radiative Transfer Model (CRTM), which is used by NOAA operational models as part of its data assimilation scheme. An improved CRTM will result in better weather forecasts via more accurate numerical weather prediction model forecasts.
Advanced Concepts Enabling Situational and Hazards Awareness via Imagery (ACES HAI)
Steve Miller, CIRA/CSU
This project aims to build on innovative work in imagery visualization techniques using the GOES-16/17 Advanced Baseline Imager. Some of the planned new applications include detection of lofted dust and snow, snow cover at night, improved nighttime low cloud detection, and spatial and temporal sharpening to approximate a mesoscale sector in regions where 1-minute data is not being collected. These improvements in ultimately result in better weather forecasts.

Andy Harris, Univ. of Maryland
This project will use Sea Surface Temperature (SST) data from current state-of-the-art imagers aboard geostationary satellites to develop a model for the daily rise and fall of SST. Frequent observations from geostationary sensors afford this capability. The diurnal heating model will in turn be used for a variety of applications, including applying it to the long-term satellite SST record in order to correct for time-of-day observations. The resulting dataset may be used for climate studies

Tony Wimmers, CIMSS/Univ. of Wisconsin
Aircraft turbulence is an important but difficult phenomenon to anticipate, particularly when it occurs in clear skies and fair weather conditions. This project will apply machine learning to data from the newest images aboard geostationary satellites in order to provide a probabilistic outlook for turbulence. Pilots can then use this information to alter their flight paths and avoid flying through regions where turbulence is expected.

This project involves building on previous work to develop a GOES-R ET and Drought product. The new product can then be used by numerical weather prediction models, resulting in an improved weather forecasts and improved drought monitoring.
Downscaling of GLM Lightning Observations Using ISS-LIS Data
Daile Zhang, Univ. of Maryland
The Lightning Imaging Sensor (LIS) currently rides aboard the International Space Station (ISS) collecting optical lightning data from storms below. At the same time, the GOES-16/17 Geostationary Lightning Mapper (GLM) provides constant hemispheric coverage, though at a more coarse spatial resolution thanks to its farther distance from Earth. This project will use machine learning techniques to combine lightning information from the two sensors when the ISS under-flies GOES-16/17, resulting in more robust and consistent lightning data for use by forecasters.

Martin Snow, Univ. of Colorado
The Extreme Ultraviolet and X-ray Irradiance Sensors (EXIS) aboard the GOES-R series includes a quadrant diode that can be used to estimate Total Solar Irradiance (TSI). Having this capability in geostationary orbit allows for a continuous TSI dataset, avoiding gaps that are necessary with TSI measured by satellites in low Earth orbit. This project will create a long-term dataset of TSI which is important for monitoring climate.

Kyle Hilburn, CIRA/CSU
This project will use data from the GOES-16/17 Advanced Baseline Imager and Geostationary Lightning Mapper to estimate precipitation as indicated by ground-based radar reflectivity. The machine learning technique is trained using radar data and has been shown to produce realistic reflectivity estimates. Reflectivity is currently used to derive latent heating profiles and is assimilated into the RAP/HRRR operational numerical weather prediction model. Satellite estimates of latent heating will allow expanded coverage of the data that is assimilated. The team plans to work toward assimilation into the FV3 model, the future operational NOAA modeling system.
Assimilation of radiance tendency of water vapor bands from geostationary satellites using FV3GFS
Jim Jung, Univ. of Wisconsin
Traditionally, satellite information is assimilated into numerical weather prediction models using the observed radiances. This method requires a bias correction, which can reduce or compromise useful information in the observations. This project involves investigation of assimilating the radiance tendency, or time rate of change of the water vapor channel radiances on the newest generation geostationary imagers. It has the distinct advantage of avoiding the bias correction step, and may lead to more accurate weather forecasts from the models.
