A New Paradigm in Model Data Fusion for the Atmosphere Observation System Constellation

Author(s): Andrew Gettelman, NCAR, Boulder, CO; and A. M. da Silva, D. J. Posselt, and G. R. Carmichael
Date: 09-Jan-2023
Location: Colorado Convention Center - 505 (Meeting Room Level)Predictions of the Earth system, such as weather forecasts and climate projections, require models informed by observations at many levels. Some methods for integrating models and observations are very systematic and comprehensive (e.g. data assimilation) and some are single purpose and customized (e.g. for model validation).

Boundary-Layer Processes over Sea Ice in Observations and Modeled with an Atmospheric-Ocean Single-Column Model (AOSCM)

Author(s): Gunilla Svensson, Stockholm Univ., Stockholm, Sweden; and K. Hartung, J. I. Holt, M. Tjernstrom, M. Karalis, A. Lewinschal, and H. Struthers
Date: 12-Jan-2023
Location: Colorado Convention Center - 504 (Meeting Room Level)The polar regions are known for their complex small-scale processes that need to be parameterised in models, such as the formation of clouds, boundary-layer mixing in ocean and atmosphere, sea ice formation/melt and the surface energy exchanges.

Comparing Dust Optical Properties in Satellite Aerosol Retrieval Algorithms (Invited Presentation)

Author(s): Robert C. Levy, GSFC, Greenbelt, MD; and P. Castellanos, P. R. Colarco, D. Giles, J. Lee, A. Lyapustin, H. Jethva, Y. Zhou, and R. A. Kahn
Date: 09-Jan-2023
Location: Colorado Convention Center - 203 (Meeting Room Level)Over the last 20+ years, there has been incredible progress in using satellite observations for deriving aerosol optical properties including dust – with reported parameters including aerosol optical depth (AOD), and under favorable retrieval conditions, single scattering albedo (SSA) and aerosol size parameters such as fine mode fraction (FMF) and Angstrom Exponent (AE). Common to many operational retrieval algorithms is the Lookup Table (LUT) approach – LUTs being forward-model simulations of typical aerosol optical properties informed by suborbital aerosol observations and theoretical modeling.

Interrogation of Heterogeneous Atmospheric Structure Through Statistical Signal Processing

Date: 09-Jan-2023
Location: Colorado Convention Center - 702 (Meeting Room Level)Photon counting is commonly employed as an optical detection technique when the instantaneous optical power is very low. This technique is highly sensitive to low light levels. For lidar, photon counting enables the capture of backscatter signals while operating low pulse energy lasers, allowing for the quantitative capture of atmospheric properties with reliable, low-cost, and eye-safe transmitters. It is also an essential technique for capturing targets at large distances and has and will likely continue to be employed in future space-based lidar missions such as AOS/ACCP.

Lidar Data Assimilation and Other Things

Author(s): Angela Benedetti, European Centre for Medium-Range Weather Forecasts, Reading, United kingdom; and W. McLean, K. Henry, J. Letertre-Danczak, and M. P. Rennie
Date: 09-Jan-2023
Location: Colorado Convention Center - 702 (Meeting Room Level)The path of science is often winding. I have started in a lidar group at University of Rome, La Sapienza in the early 90s' and ended up doing lidar data assimilation at the European Centre for Medium-Range Weather forecasts for the last 20 years, passing through Colorado State University for a PhD. I would like to share my experience working with lidar data from the point of view of the user. Examining how each choice has led to the subsequent steps can help young researchers find their own path in the field.

Machine Learning Techniques for Determining Cloud Phase Using Backscatter Lidar: Observations from IMPACTS and Implications for AOS

Date: 09-Jan-2023
Location: Colorado Convention Center - 702 (Meeting Room Level)Clouds play important roles in Earth's climate system and that role is heavily dependent on the height, thickness, and particle properties of clouds in the atmosphere. Liquid water clouds closer to the Earth's surface tend to reflect incoming sunlight, cooling Earth's surface. However, ice clouds can absorb heat emitted from the surface and re-radiate it back down, warming Earth's surface. Thus, determining cloud phase (liquid or ice) is important to understanding cloud impacts on the radiation budget. Cloud-aerosol lidars are important tools for estimating cloud height, thickness, and cloud phase.

The ALICAT Lidar for the Atmospheric Observing System (AOS) Inclined Orbit: Instrument Overview and Projected Performance

Date: 11-Jan-2023
Location: Colorado Convention Center - 702 (Meeting Room Level)The Atmospheric Lidar for Clouds and Aerosol Transport (ALICAT) is a SmallSat elastic backscatter lidar planned to fly in the AOS inclined orbit with an anticipated launch in summer 2028. Providing vertical measurements of attenuated backscatter and volume depolarization ratio at 532 and 1064 nm in an orbit with a 55-degree inclination, ALICAT will provide critical measurements of diurnal variability of clouds and aerosol profiles coincident with other AOS instrumentation, notionally a Ku-band radar and microwave radiometer in the inclined orbit for a planned 3-year lifetime.

Date: 09-Jan-2023
Location: Colorado Convention Center - 203 (Meeting Room Level)NASA's future Earth System Observatory (ESO) will provide key information related to understanding climate change processes, mitigating natural hazards, fighting forest fires, and improving real-time agricultural processes. The Atmosphere Observing System (AOS) constellation is a key component of the ESO, providing the atmospheric part of the ESO and focusing on two of the five designated observables from the 2017 NASA Earth Science Decadal Survey: aerosols and clouds, convection, and precipitation (CCP).

Uncertainty in Observational Estimates of Aerosol Radiative Effects: Current and Future Satellite Capabilities (Invited Presentation)

Date: 11-Jan-2023
Location: Colorado Convention Center - 203 (Meeting Room Level)Aerosols continue to be responsible for the largest uncertainty in determining the anthropogenic radiative forcing of the climate. To both reconcile the large range in satellite-based estimates of the aerosol direct radiative effect (DRE, the direct interaction with solar radiation by all aerosols) and to optimize the design of future observing systems, we build a framework for assessing uncertainty in aerosol DRE and the aerosol direct radiative forcing (DRF, the radiative effect of just anthropogenic aerosols, RF_ari).
