Spectral Bands & Resolution

GOES-ABI-bands

Data Quality Flag

The Data Quality Flag (DQF) is provided with each radiance file, and shows the following values:

  • 0 --> Good pixel quality
  • 1 --> Conditionally usable pixel quality
  • 2 --> Out of range pixel quality
  • 3 --> No value pixel quality
  • 4 --> Focal Plane Temperature Threshold Exceeded

Working with Level-1B Data

GOES/ABI radiances are provided in $mW/m^2/sr/cm^{-1}$, i.e. the data is normalised to wavenumbers. In order to convert the data to $W/m^2/sr/um$, the data needs to be multiplied by $10^{-7}$; $mW = 10^{-3} W$, $cm^{-1} = 10^4 {um}$.
