[IDL] RGB Synthesis Using Himawari-8/AHI Weather Satellite Data and Superposition of Aerosol Optical Thickness (AOD) From COMS/MI Weather Satellite Data

Posted at

[Characteristic]

  • Synthesis and superposition techniques are required for the Clianian Satellite 1 (COMS/MI) and Himawari Satellite 8 (Himawari-8/AHI) data, and this program is designed to achieve this purpose.

[Function]

  • Read longitude and binary data for Terra/MODIS data Read Himawari-8/AHI data
  • Read raw data and convert to reflectance for Himawari-8/AHI materials
  • Calculate solar zenith angle (SZA), solar azimuth (SAA), satellite zenith angle (VZA), satellite azimuth (VAA), and relative azimuth (RAA) for RGB composite images
  • Conversion to Red, Green, Blue using reflectance for each channel
  • Read raw data for COMS/MI data and convert to aerosol optical thickness
  • Aerosol Optical Thickness Mapping After RGB Synthesis

[How to]

  • Locate Terra/MODIS data in the same directory
  • Run source code (idl -e Visualization_Using_Terra_MODIS_Data)Check the visualization result
  • Stores Cheonlian Satellite 1 and Himawari Satellite 8 data in the same directory
  • Run source code (idl -RGB_Composite_Image_Using_Himawari8_Data_And_Aerosol_Optical_Thickness_Superimposition_Using_COMS_Data)
  • Check the visualization result

[OS]

  • Linux
  • Window 10

[Language]

  • IDL

[Source Code]

[Result]

  • RGB synthesis using Himawari-8/AHI data and superposition of aerosol optical thickness (AOD) from COMS/MI data image.png
