Theme
Remote sensing data analyses for Cloud, Water vapor, Aerosol and Solar radiation studies.
Keywords
  • Cloud, Water vapor, Aerosol, Solar radiation
  • Passive optical sensors, Remote sensing data
  • Algorithm development, Data analysis, Look-up table, Inversion
  • Atmospheric science, Radiative transfer theory, Meteorology, Climatology
Facilities and Tools
  • Data analysis system with UNIX on Macintosh computers.
  • Softwares with C, FORTRAN, IDL and so on.
Perspectives
I analyze remote sensing data obtained from satellite, aircraft, and ground-based observations to investigate atmospheric environment in terms of cloud, water vapor, aerosol, and solar radiation.
The spatiotemporal variation of the meteorological elements is fundamental to weather forecasting, for example. Furthermore, the research has been important for application to photovoltaics utilities, because solar radiation at surface strongly depends on the amount of cloud, water vapor, and aerosol.
I utilize computer programming for the data analyses, using C, Fortran, and IDL on UNIX systems, because the earth observation data are usually a large amount of volumes.
Based on the outcomes from the above investigations, I collaborate with space agencies on future observation missions.
Examples
  • Cloud
  • Water vapor
  • Aerosol
