Research Interests

  • Scientific computation and applications, including instrument modeling and calibration, passive infrared and microwave sounding, radiative transfer calculations, and parallel and distributed processing.

Projects

  • Calibration analysis of CrIS, the Cross-track Infrared Sounder, a hyperspectral infrared sounder for the NPOESS next-generation weather satellite. This involves analyzing gas cell and laser calibration test data to verify the spectral calibration of the instrument, reading telemetry packets, processing these to produce observed spectra, modeling self-apodization and other optical and interferometric effects, and comparing observed and calculated spectra.

  • Administering and maintaining a computing cluster and data system with 6 RAID servers, 90 Tbytes of RAID, a web/FTP/gateway server, 28 dual-processor cluster nodes, and assorted desktop machines. Also, providing user support for the system.

  • Managing large databases for atmospheric science, including scripts and tools to automate downloads from NASA and NOAA archives and tools for indexing and querying large local data sets.

  • Developing and parallelizing applications to run on our cluster, including the calculation and analysis of upwelling radiance from the data sets mentioned above, and the periodic refinement and recalculation of the tabulated compressed optical depths used for those radiative transfer calculations.

  • Calibration and validation studies of AIRS, the Atmospheric Infrared Sounder, including detailed instrument modeling, analysis of pre-launch calibration measurements, and the comparison of calculated and observed spectra after launch.

  • Statistical and physical temperature and humidity profile retrievals with simulated AIRS infrared radiances, and statistical temperature and humidity profile retrievals with microwave data from SSM-T/T2/I sounders.

Software

  • A package for radiative transfer calculations from compressed tabulated optical depths (a Matlab version of "kcarta"), and tools and scripts for building a database of compressed tabulated optical depths from HITRAN data.

  • Tools and sample applications for gridded analysis of profile and radiance data for very large data sets; demo applications of VIS and MODIS image manipulation and mapping, and demo applications of eigenvector compression and filtering of AIRS radiance data.

  • The RTP (Radiative Transfer Profile) package, an HDF 4 data format and application interface for storage and manipulation of atmospheric profiles and associated spectra. Also assorted Matlab HDF 4 tools, including a Matlab RTP interface.

  • HITRAN IR cross section tools--Matlab procedures to read and manipulate IR cross section data, including a procedure to return absorptions calculated from interpolation or extrapolation of HITRAN tabulated cross-section data. Also, tools to access and manipulate manipulate HITRAN-format data.
