    I am a research scientist employed by Columbia University and working at NASA's Goddard Institute for Space Studies (GISS) in New York. My research focuses on remote sensing of ice cloud properties and evaluation of ice formation processes in cloud resolving models.

    Research Interests

    Global observations of the fundamental radiative and microphysical properties of ice clouds

    A continuing area of uncertainty in modeling clouds and consequently their feedbacks is in the radiative properties of clouds and ice clouds in particular. The fundamental radiative properties of ice clouds for global climate model projections can be represented in terms of cloud optical thickness (COT), effective ice crystal size (Reff) and the first moment of the scattering phase function, commonly referred to as the asymmetry parameter. Conventional satellite instruments, such as MODIS, allow global estimates of COT and Reff. However, very little is known about the natural variation of the asymmetry parameter of ice crystals, which is mainly determined by the crystal shape. Moreover, retrievals of COT and Reff depend on the asymmetry parameter of fixed assumed ice properties, leading to uncertainties in both parameters that can exceed 50%. Improved knowledge about the global distribution of ice COT, Reff, asymmetry parameter and particle shape is crucial to better evaluate and advance our current cloud modeling capabilities.

    I recently developed a new technique to infer ice crystal asymmetry parameter and shape characteristics from remote sensing measurements. Natural ice clouds generally contain a virtually unlimited variation of complex, aggregated crystals, which makes remote sensing of the exact shape distributions of ice crystals in tops of clouds essentially impossible. We reduce this retrieval problem by focusing on the retrieval of aspect ratios of crystal elements and crystal distortion or roughness (parameterized as a stochastic large-scale distortion of a collection of ice crystals as by Macke et al. 1996). Essentially, this method uses single hexagonal columns and plates as radiative proxies for more complex shapes. We demonstrated that aspect ratios and distortion parameters can be robustly retrieved from multi-direction polarized reflectance measurements. Subsequently, the ice crystal asymmetry parameter is deduced from the retrieved aspect ratios and crystal distortion values. Moreover, this approach allows for a subsequent retrieval of COT and Reff that is not biased by the use of a predetermined fixed asymmetry parameter.

    We evaluated this retrieval technique using simulated measurements based on state-of-the-art optical properties of complex ice crystal shapes and mixtures (Baum et al., 2011; Yang et al. 2013). The evaluation showed that, for individual measurements, the asymmetry parameter is generally retrieved to within 5%, which is also the limit specified by Vogelman and Ackerman (1995) needed to sufficiently constrain radiative effects of ice clouds on global climate. Furthermore, this approach is evaluated by applying it to measurements of GISS’ airborne Research Scanning Polarimeter (RSP).

    In future work, we aim to document and analyze any observed relationships between ice cloud properties, cloud type and environment. This will be achieved by applying the method to combined measurements of the POLDER and MODIS satellite instruments and to RSP measurements obtained during the SEAC4RS field campaign and other campaigns.

    Evaluation and parameterization of optical properties of ice crystals

    Based on the same principles of using single hexagonal columns and plates as radiative proxies for more complex shapes, I constructed a simple yet flexible parameterization that provides the extinction cross section, single-scattering albedo and asymmetry parameter of ice crystals with any combination of volume, projected area, aspect ratio (of crystal components) and crystal distortion and at any wavelength in the shortwave (van Diedenhoven et al., JAS 2014). The parameterization scheme consists of only 88 coefficients and has comparable or better accuracy than similar other schemes that are more complex and less flexible. This scheme allows calculating ice crystal optical properties that are consistent with any assumptions or predictions of ice crystal shape and sizes of cloud resolving models (CRM) or climate models. A very simple computer code of this parameterization is publically available and the scheme is being implemented in the GISS CRM. I aim to further improve this parameterization where possible and to continue to advocate and advise on the implementation of the scheme in other cloud and climate models and in other projects.

    Addressing concerns about possible biases in ice cloud radiative properties simulations and retrievals related to the use of geometric optics, I recently participated in an investigation into this issue (Bi et al., JQSRT 2013). We demonstrated that such biases are small for most cloud conditions, especially compared to errors and biases resulting from other issues, such as uncertainties in asymmetry parameters. However, errors can be substancial for clouds with low optical thickness and small effective radii.

    Optical phenomena by cloud ice crystals

    I recently demonstrated the persistence of 22-degree halo features in phase functions of mixtures of pristine and distorted crystals. This provides a simple, plausible explanation for why halos at 22 degrees from the sun that result from pristine hexagonal ice crystals are prevalent, although other observations indicate a dominance of non-pristine, roughened and distorted ice crystals in ice clouds (van Diedenhoven, JQSRT, 2014).

    Advancement of hyperspectral and polarimetric measurements for improved Earth observations

    Another objective of my work is the advancement of polarimetry for improved Earth observations in general. As such I am active member of the RSP team and co-I on (funded and proposed) projects that aim to use polarimetry to provide improved atmospheric correction for ocean color retrievals and improved characterization of surface snow. For this, I also draw on my past experiences of working with hyperspectral data, the Oxygen A-band and lidar measurements.

    Current Projects

    Global variation of the fundamental radiative and microphysical properties of ice clouds

    We aim to document and analyze any observed relationships between ice cloud properties, cloud type and environment using total and polarized reflectance measurements. This will be achieved by applying the method to combined measurements of the POLDER and MODIS satellite instruments and to RSP measurements obtained during the SEAC4RS field campaign and other campaigns.

I aim to further improve this parameterization where possible and to continue to advocate and advise on the implementation of the scheme in other cloud and climate models and in other projects.
